This report analyzes the challenges faced by small-scale farmers and explores potential solutions to help them adapt to new technologies while maintaining their traditional farming practices. The research delves into the daily life journey of small-scale farmers, including their agricultural practices and the rural community. The author conducted 20 days of field research in a rural area of China and discovered that many of these small farms operate on a tight budget, and farmers rarely use machines to cultivate their land. The thesis project offers a complete solution with a weather station, soil sensor, and app. The weather station is shared by the entire village and provides real-time weather data to farmers. Soil sensors, owned by farmers and placed near crops, provide real-time data on soil moisture, temperature, and nutrient levels. The app provides a user friendly interface for farmers to access the data collected by both the soil sensor and weather station. This project provides a vision to help farmers manage their crops better and accurately forecast their crop yield.

В данной выпускной квалификационной работе стоит цель разработать антенную систему МС, в которую войдут одна антенна: секторная или кольцевая ФАР, с возможностью сканирования пространства в горизонтальной плоскости в диапазоне от 0 до 360 градусов. Обязательное требование, предъявляемое к антенне с электронным сканированием – при отклонении ДН на определённый угол уровень равносигнального направления между соседними ДН не должен быть ниже -2 дБ. Это позволит стабилизировать связь при переключении между соседними каналами с метеорологическим зондом, который может находиться в любом направлении относительно стационарного пункта наблюдения на МС. / In this final qualifying work is the aim to develop an antenna system MS, which will include one antenna: sector or ring of lights, with the ability to scan space in a horizontal plane in the range from 0 to 360 degrees. Mandatory requirement for the antenna with electronic scanning – rejecting days to a certain angle the level of the equisignal direction between adjacent days should not be below -2 dB. This will allow to stabilize the connection when switching between adjacent channels with a meteorological probe, which can be in any direction relative to a stationary point of observation on the MC.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / During engine and airfield performance testing it is often necessary to acquire weather data at the airfield where the test is being conducted. The airborne data acquisition system (DAS) acquires data associated with flight parameters. A separate system records airport weather conditions. Many times the separate system is an Automated Terminal Information Service (ATIS) or the ground crew relaying wind speed, wind direction and temperature from a weather station. To improve this system, the weather station is designed to acquire and store the data in memory. Utilizing a second DAS that is remote to the airborne DAS poses several problems. First, it is undesirable to have many different data acquisition systems from which to process data. The problem then develops into one of integrating the ground weather DAS with the existing airborne DAS. Other problems of system integrity, compatibility and FCC licensing exist. Complete system integration while maintaining integrity and compatibility is overcome by controlling signal format, flow and timing and is discussed in detail. Further discussion of the issue of transmission is overcome by a technique called spread-spectrum and is used in accordance with FCC rules and regulations.

In this project, we analyse the ability of two regional climate models to simulate meteorological conditions on Nordenskiöldbreen, a glacier in Svalbard. To do so, regional climate model output is compared with in situ measurements from an automatic weather station. Detailed information about the weather conditions on Nordenskiöldbreen is important for simulating the glacial mass balance in a changing climate. The parameters analysed were the following: temperature, air pressure, relative humidity, precipitation, cloud cover, wind speed and wind direction. The weather station did not measure all parameters, cloud cover was instead estimated through the incoming longwave radiation and temperature, while precipitation was calculated from snow depth. The results show that the models represent certain parameters better than others. Temperature, air pressure and wind speed and direction are found to be simulated with high precision. Poorest agreement is found for precipitation, which appears to be both difficult to simulate and observe. Relative humidity and cloud cover show average agreement with the station. The conclusion of the project is that the estimation of some of the parameters is satisfactory, while others are lacking. None of the models can be determined to have performed significantly better than the other. / I det här projektet analyserades två regionala klimatmodellers förmåga att simulera meteorologiska förhållanden på Nordenskiöldbreen, en glaciär på Svalbard. Detta gjordes genom jämförelser av data från regionala klimatmodeller mot lokala mätningar från en automatisk väderstation. Detaljerad information om väderförhållandena på Nordenskiöldbreen är viktigt för att kunna simulera glaciärens massbalans i ett föränderligt klimat. Parametrarna som jämfördes var temperatur, lufttryck, relativ luftfuktighet, nederbörd, molntäcke samt vindhastighet och vindriktning. Stationen mätte inte alla parametrar, molntäcket uppskattades istället genom inkommande långvågig strålning och temperatur, medan nederbörd beräknades via snödjup. Resultatet visar att modellerna representerar vissa parametrar bättre än andra. Temperatur, lufttryck, vindhastighet och vindriktning simuleras med hög precision. Parametern med lägst samband är nederbörd, somverkar vara svår både att simulera och observera. Relativ luftfuktighet och molntäcke har ett medelmåttigt samband till stationen. Slutsatsen av projektet är att modellernas uppskattning av några parametrar är tillräckligt bra, medan andra är bristfälliga. Ingen av modellerna kan bedömas ha presterat signifikant bättre än den andra.

Weather conditions have significant impact on road safety and roadway maintenance operations. Road Weather Information Systems (RWIS) play a significant role in providing weather and surface conditions to transportation agencies to monitor weather events. Fixed installations of RWIS are used for weather and pavement surface monitoring. However, permanent fixture installations may not be feasible due to reasons such as cost, accessibility to the site, siting concerns, and terrain. Portable RWIS provide a cost-effective solution in areas where permanent weather station installation is not possible. This study discusses use and benefits of the portable RWIS and outlines the issues involved in building them. This thesis presents the system design for building prototypes of two portable RWIS systems to be used by Massachusetts Department of Transportation (MassDOT). Portable RWIS consist of weather sensors and pavement sensors installed on a trailer-based platform and operate on solar power. The RWIS equipment mounted on trailers consists of non-invasive pavement sensors, wind sensor, precipitation sensor, atmospheric pressure sensor, humidity and dew point sensor and data logger to transmit data from the sensors to a central server. RWIS equipment from two different manufacturers have been selected. The two systems have been evaluated for their cost, operability, ease- of-use and deployability. A field study of two portable RWIS has been conducted to test accuracy of the data collected by these systems and the results have been evaluated. Characterizing the issues involved in developing such portable systems provide insights into situations where these systems may be most applicable.
