Wet Bulb Globe Temperature (WBGT) is used to assess categorical heat stress risk factors for individuals working in outdoor environments and to provide guidelines for work/rest ratios and water intake. The variables required to compute WBGT are used by meteorologists for many purposes and are available through the Copernicus Program which was implemented by European Centre for Medium-Range Weather Forecasts (ECMWF) to provide users access to ECMWF Re-Analysis (ERA) historical database. WBGT values for Tennessee during National Weather Service (NWS) issued excessive heat warnings were calculated to determine the need for additional advisories based on WBGT guidelines. Monthly average WBGT values suggest work/rest ratio thresholds were exceeded in areas with no active heat warnings during the same time. Site assessment for an improved weather station infrastructure was conducted to determine favorability for placement of additional instrumentation to benefit forecasters and general public with greater data availability on a temporal scale.

abstract: Exertional heat stroke continues to be one of the leading causes of illness and death in sport in the United States, with an athlete’s experienced microclimate varying by venue design and location. A limited number of studies have attempted to determine the relationship between observed wet bulb globe temperature (WBGT) and WBGT derived from regional weather station data. Moreover, only one study has quantified the relationship between regionally modeled and on-site measured WBGT over different athletic surfaces (natural grass, rubber track, and concrete tennis court). The current research expands on previous studies to examine how different athletic surfaces influence the thermal environment in the Phoenix Metropolitan Area using a combination of fieldwork, modeling, and statistical analysis. Meteorological data were collected from 0700–1900hr across 6 days in June and 5 days in August 2019 in Tempe, Arizona at various Sun Devil Athletics facilities. This research also explored the influence of surface temperatures on WBGT and the changes projected under a future warmer climate. Results indicate that based on American College of Sports Medicine guidelines practice would not be cancelled in June (WBGT≥32.3°C); however, in August, ~33% of practice time was lost across multiple surfaces. The second-tier recommendations (WBGT≥30.1°C) to limit intense exercise were reached an average of 7 hours each day for all surfaces in August. Further, WBGT was calculated using data from four Arizona Meteorological Network (AZMET) weather stations to provide regional WBGT values for comparison. The on-site (field/court) WBGT values were consistently higher than regional values and significantly different (p<0.05). Thus, using regionally-modeled WBGT data to guide activity or clothing modification for heat safety may lead to misclassification and unsafe conditions. Surface temperature measurements indicate a maximum temperature (170°F) occurring around solar noon, yet WBGT reached its highest level mid-afternoon and on the artificial turf surface (2–5PM). Climate projections show that WBGT values are expected to rise, further restricting the amount of practice and games than can take place outdoors during the afternoon. The findings from this study can be used to inform athletic trainers and coaches about the thermal environment through WBGT values on-field. / Dissertation/Thesis / Masters Thesis Geography 2020

<p dir="ltr">Robust and actionable information regarding how heat stress will change as climate warms is essential for informing impact assessments and heat mitigation and adaptation strategies. In meeting this demand, this dissertation has two mutually reinforcing goals: to improve heat stress prediction through a more comprehensive account of human heat stress, and to advance our understanding of the driving mechanisms of model-predicted heat stress changes.</p><p dir="ltr">As the initial step in achieving the first goal, we adopt the wet-bulb globe temperature (WBGT) as our preferred metric for heat stress. Then we (i) develop a fast, scalable Python implementation of the “gold standard” physics-based WBGT model, (ii) devise a straightforward, yet effective statistical bias-correction approach, and (iii) generate a global dataset of bias-corrected heat stress prediction at fine spatial and temporal resolutions based on a CMIP6 model ensemble. </p><p dir="ltr">To achieve our second goal of understanding the driving mechanisms of WBGT changes, we take advantage of the underlying physical relationship between WBGT and the simpler, wet-bulb temperature to gain insights into WBGT by first (i) investigating the soil moisture control of wet-bub temperature under present conditions and (ii) using CMIP6 results to understand future changes of wet-bulb temperature. Then, (iii) we develop a linear sensitivity framework that is used to disentangle WBGT changes into contributions from changes in temperature, humidity, wind, solar radiation and surface pressure. This disentanglement enables us to leverage existing theories and methods to understand the driving mechanism of WBGT changes.</p><p dir="ltr">Through this work we find several noteworthy conclusions, which is explained in depth in the rest of the dissertation, but we briefly summarize here. Wide-spread positive coupling between soil moisture and wet-bulb temperature are found over previously identified land-atmosphere coupling hotspots due to the effective control of soil moisture variations on surface energy partition and boundary layer dynamics. This implies that drying-induced amplified warming may be counteracted by relative humidity reductions, and a potential mismatch between relative hotspots of warming and intensifying heat stress. We confirm this hypothesis by showing distinctly different scaling patterns (with global warming) between dry-bulb temperature and WBGT based on a CMIP6 model ensemble. Regionally amplified warming in northern hemisphere mid-latitudes and the Amazon correspond to muted increases in WBGT. The central Sahel emerges as a strong local hotspot of WBGT scaling.</p><p dir="ltr">The sensitivity framework predicts close similarity between the scaling of black globe and natural wet-bulb temperature (two major components of WBGT) and that of dry- and wet-bulb temperature, if wind speed and solar radiation changes have a minor impact. This is confirmed to be the case in a CMIP6 model ensemble, with WBGT scaling primarily influenced by temperature and humidity changes. </p><p dir="ltr">Combining these results together holistically, we reach the following conclusions. Although the widely used and empirically well validated WBGT heat stress metric is a complex function of four environmental variables, as climate changes, the changes in WBGT predicted by climate models can be mostly understood in terms of changes in near-surface air temperature and humidity. Furthermore, the linear sensitivity framework and scaling analyses developed here allow us to partially attribute the WBGT scaling pattern to regional drying or wetting trends, and associated changes in surface energy balance and boundary layer dynamics. Thus, accurate prediction of WBGT changes is to first order largely a matter of getting those temperature and humidity correct and improvements to theories and models for those fields will directly translate to improvements in WBGT prediction as well. </p>

In all the experiments were used with roofing cement tile, new, no asbestos cement, with 4.0 mm thick. The first experiment was conducted at the Universidade Estadual do Maranhão (UEMA), campus of São Luís, where were tested five types of coverage: 1 - no shading, no paint (STSP - control), 2 - with shading 0.05 m in height tile, unpainted (CT5SP) 3 - with shading 0.05 m in height tile with painting (CT5CP) 4 - with shading 0.08 m in height tile, unpainted (CT8SP) and 5 - with shading 0.08 m height of the tile with painting (CT8CP). Were evaluated the index of black globe temperature and humidity (BGTHI), the Heat Load (HL) and the specific enthalpy (H). The readings of meteorological variables (black globe temperature, dry bulb, wet bulb temperatures and wind speed) were measured during 12 experimental days (from nov. 4th to 15th, 2009) at 10:00, 12:00, 14: 00 and 16:00 hours. The type of coverage CT5SP had the lowest values for BGTHI (79,81) and H (78,84 KJ.Kg-1 dry air). The best result for CTRcorr (480,12 W.m-2) was presented by treatment CT5CP. The second experiment was conducted at Universidade Estadual Paulista (UNESP), campus of Jaboticabal, where were tested the same types of coverages of Experiment 1. The collection and recording of meteorological variables were performed for 40 days (from feb. 13th to 24th, 2010), at the same times of Experiment 1. The type coverage that provided smaller results for the BGTHI (83,86) and H (86,41 KJ.Kg-1 dry air) was CT8CP. The lower HL (549,52 W.m-2) was verified with the coverage CT5CP. The third experiment aimed at assessing the effect of two types of shading screens (50 and 80%) on the thermal comfort...

As there has been an increase in the insertion of technological innovations of communication and information (news ICT) in educational institutions, which can contribute to the increase in thermal radiation, it is therefore important to investigate how this increase in these environments may interfere with the comfort and performance of students. In the equation formulated by Fanger (1970), the thermal radiation factor is represented by the mean radiant temperature (Trm), but its impact on thermal comfort is often ignored. The globe temperature (Tg) is one of the variables of the equations for the calculation of the mean radiant temperature. It corresponds to the temperature that allows evaluating the level of thermal radiation of the existing surfaces in an environment where a significant difference between the globe temperature and the temperature of the air can demonstrate some increase of thermal radiation in the work environment. Objective: To investigate if the behavior of the globe temperature in relation to the air temperature (Tg-Ta), observing the variation of the mean radiant temperature, could have repercussion in the performance of students in intelligent teaching environments in areas of the Brazil's regions. Methods: The methodological procedures adopted in this work consisted of the following steps: analysis of thermal variables: Trm and (Tg-Ta); analysis of students' performance, analysis of architectural elements and construction of the mathematical model. The study was carried out in computerized laboratories with News ICT in the following institutions: UFPI, Teresina-Piauí (A); UFSC, Florianópolis-Santa Catarina (B); UnB, Brasília-Federal District (C); UNIVASF, Petrolina-Pernambuco (D); ICMC, São Carlos-SP (E); UFAM, Manaus-Amazonas (F); CE of the PM, João Pessoa, Paraíba (G). The students answered a questionnaire adapted from the Bateria de Provas de Raciocínio (BPR-5) on three consecutive days at different temperatures, while the thermal conditions were measured and the design and architectural elements were analyzed. Results: It was verified that in the three consecutive days, there was no heat exchange by radiation between the student and his environment in the laboratories of institutions C and F, demonstrating that in the other laboratories of institutions A, B, E and G there was heat exchange by radiation. It is noteworthy that in the laboratory of institution G this heat exchange was more pronounced, such that the mean radiant temperature at any given time exceeded the globe temperature at 2.25°Chcg/ 𝜀𝑔𝜎. However, their architectural analysis signaled that the design was adequate. So probably, the heat sources inside the laboratory should have provided increased thermal radiation, given that the number of students and laptops were representative. Thus, in the sense of confirming these findings, it was verified through the mathematical modeling that with each increase of one degree in the difference between the globe temperature and the air temperature (Tg-Ta), the students' performance in the computer laboratory of the Institution G decreased by around 29%. Therefore, the higher the mean radiant temperature, the higher the thermal radiation in this laboratory, and this increase may compromise student performance. Conclusion: Productivity may change due to changes in air temperature in air-conditioned teaching environments, as has already been demonstrated by international publications. In this specific case, if Tg >> Ta, the thermal radiation may possibly interfere with the performance of people present in environments equipped with technological innovations in communication and information (News ICT). / Introdução: As alterações climáticas do planeta poderão elevar ainda mais a temperatura média em todas as regiões do Brasil, e como tem havido um crescimento da inserção de inovações tecnológicas de comunicação e informação (news ICT) em ambientes de ensino, o que pode colaborar para o aumento da radiação térmica, torna-se assim importante investigar como esse aumento nesses ambientes poderá interferir no conforto e desempenho de estudantes. Na equação formulada por Fanger (1970), o fator de radiação térmica é representado pela temperatura radiante média (Trm), mas seu impacto sobre o conforto térmico é muitas vezes ignorado. A temperatura de globo (Tg) é uma das variáveis das equações para o cálculo da temperatura radiante média e a mesma corresponde a temperatura que permite avaliar o nível de radiação térmica das superfícies existentes em um ambiente donde uma diferença significativa entre a temperatura de globo e a temperatura do ar pode demonstrar certo aumento da radiação térmica no ambiente de trabalho. Objetivo: Investigar se a relação entre a temperatura de globo e a temperatura do ar (Tg-Ta), observando a variação da temperatura radiante média, poderá ter repercussão no desempenho de estudantes em ambientes inteligentes de ensino (News ICT) em áreas das regiões brasileiras. Métodos: Os procedimentos metodológicos adotados neste trabalho consistiram nas etapas: análise das variáveis térmicas: trm e (tg-ta); análise do desempenho dos estudantes, análise dos elementos arquitetônicos e construção do modelo matemático. O estudo foi realizado em laboratórios de informática climatizados com News ICT nas seguintes instituições: UFPI, Teresina-Piauí (A); UFSC, Florianópolis-Santa Catarina (B); UnB, Brasília-Distrito Federal (C); UNIVASF, Petrolina-Pernambuco (D); ICMC, São Carlos-SP (E); UFAM, Manaus-Amazonas (F); CE da PM, João Pessoa, Paraíba (G). Os estudantes responderam a um questionário adaptado da Bateria de Provas de Raciocínio (BPR-5) em três dias consecutivos a diferentes temperaturas, enquanto as condições térmicas eram medidas e o projeto e elementos arquitetônicos eram analisados. Resultados: Constatou-se que nos três dias consecutivos só não houve troca de calor por radiação entre o estudante e seu ambiente nos laboratórios das instituições C e F, demonstrando que nos outros laboratórios das instituições A, B, D, E e G houve troca de calor por radiação. Ressalta-se que no laboratório da instituição G essa troca de calor foi mais acentuada, tal que a temperatura radiante média em dado instante superou a temperatura de globo em 2,25 °C hcg/ 𝜀𝑔𝜎. Entretanto, sua análise arquitetônica sinalizou que o projeto tinha mais aspectos positivos.Logo, provavelmente as fontes de calor no interior do laboratório devem ter proporcionado aumento da radiação térmica, haja vista que o número de estudantes e laptops eram representativos. Assim, no sentido de confirmar esses achados, constatou-se através da modelagem matemática que a cada aumento de um grau na diferença entre a temperatura de globo e a temperatura do ar (Tg-Ta), o desempenho dos estudantes no laboratório de informática da instituição G diminuía em torno de 29%, constatando que, quanto maior a temperatura radiante média, maior será a radiação térmica nesse laboratório, e esse aumento poderá comprometer o desempenho dos estudantes. Conclusão: Como a produtividade pode sofrer alterações devido às mudanças de temperatura do ar em ambientes de ensino climatizados, conforme já comprovado por publicações internacionais, neste caso específico, se Tg>>Ta, possivelmente a radiação térmica poderá interferir no desempenho das pessoas presentes em ambiente providos de inovações tecnológicas de comunicação e informação (News ICT).

Exposure to high heat and humidity can lead to serious health risks, including heat exhaustion and heat stroke. Wet Bulb Globe Temperature (WBGT) and heat index have historically been used to predict heat stress events, but individualized factors are not included in the measurement. It has been shown that there is a relationship between cardiovascular measurements and heat stress, which could be used to measure heat stress risk on an individual level. Research has been done to find relationships between cardiovascular metrics in a workplace environment, however the study did not include the use of a controlled environment as a baseline. This study provides measurements of transepidermal water loss (TEWL), heart rate, body core temperature, and blood pressure in a controlled environment when human subjects are exposed to high heat and humidity. Thirty subjects (n=17 females, 13 males) were asked to self-express their activity level (active vs. sedentary), gender, and age. The subjects performed a 30-minute moderate exercise routine on a stationary stepper machine in a heated environmental chamber (average WBGT of 26ºC). TEWL, heart rate, tympanic temperature, and blood pressure were recorded at every 10-minute increment of the exercise protocol per subject. The data was analyzed using JMP® software to find significant (P

Teplota vzduchu je nejčastěji používaná k posouzení tepelného stavu vnitřního prostředí. Avšak teplota vzduchu sama o sobě, je v mnoha případech pro toto posouzení nedostatečná. Hlavním cílem disertační práce je vyhodnotit tepelný stav vnitřního prostředí a specifikovat parametry, které na něj mají vliv. Teplota vzduchu, střední radiantní teplota, rychlost vzduchu a vlhkost vzduchu jsou čtyři základní parametry, které určují tepelný stav vnitřního prostředí. Vzhledem k tomu, že tepelný stav prostředí závisí na mnoha aspektech, byly odvozeny veličiny, které zahrnují kombinovaný účinek několika nebo všech těchto parametrů k určení tepelného stavu prostředí. Jedná se např. o efektivní teplotu, teplotu kulového teploměru, operativní teplotu, ekvivalentní teplotu, PMV a PPD indexy... aj. V dnešní době existuje spousta vysoce přesných senzorů, které mohou zhodnotit tepelný stav vnitřního prostředí. Z důvodu jejich vysoké ceny jsou používané převážně pro účely výzkumu. Předkládaná práce se převážně soustředí na vývoj kompaktního deskového senzoru pro vyhodnocení tepelného stavu vnitřního prostředí. Zaměřuje se hlavně na nízkou cenu senzoru společně s dostatečnou přesností. K dosažení cíle této práce jsou provedeny následující postupy: • Analýza environmentálních faktorů ovlivňujících tepelný stav prostředí. • Studium dopadu teploty vzduchu, střední radiantní teploty a rychlosti proudění vzduchu na tepelné indexy: teplotu kulového teploměru a operativní teplotu. • Teoretické porovnání teploty kulového teploměru a operativní teploty. • Navržení, rozvoj a konstrukce nového deskového senzoru pro posouzení tepelného stavu vnitřního prostředí. • Navržení a konstrukce testovací komory pro porovnávání senzorů tepelného stavu prostředí. • Kalibrace zkonstruovaného senzoru měřením fyzikálních veličin charakterizujících tepelný stav prostředí. • Testy směrové závislosti vyvinutého deskového senzoru a porovnání s kulovým teploměrem v testovací komoře. • Srovnání teoretických řešení s provedenými měřeními v testovací komoře. Výsledkem této práce je vlastní teoretické srovnání teploty kulového teploměru a operativní teploty ve vybraném rozsahu teploty vzduchu, střední radiantní teploty a rychlosti vzduchu pro možnost hodnocení tepelného stavu vnitřního prostředí pomocí kulového teploměru. Hlavním výstupem je však navržení a zhotovení jednoduchého deskového senzoru, který by byl dostatečně přesný pro měření tepelného stavu prostředí. V rámci disertace byla postavena také testovací komora a bylo provedeno testování vyvinutého senzoru pomocí měřicího systému INNOVA.
