Photoacoustic spectroscopy was used to analyze the transport of ozone through the air/water interface. Experimental results showed that the ozone transport rate is similar to rates measured for other gases of low solubility and low reactivity. The transport rate increases with increasing pH. The decomposition rate of ozone was studied in solutions. The decomposition rate also depends on the pH of the solution, and in high pHs both the deposition velocity and the decomposition rate constant of ozone have larger values. The value of the deposition velocity (Kd) is 3.7 ± .9 x 10-3 cm/sec and the decomposition rate constant is 5.3 ± 0.6 x 10-5 sec-l for distilled water. For ocean water, the respective values are 5.2 ± 0.4 x 10-3 sec-l and 7.8 ± 0.4 x 10-4 cm/sec respectively.

Meteorological variables such as temperature, wind speed, wind directions, and Planetary Boundary Layer (PBL) heights have critical implications for air quality simulations. Sensitivity simulations with five different PBL schemes associated with three different Land Surface Models (LSMs) were conducted to examine the impact of meteorological variables on the predicted ozone concentrations using the Community Multiscale Air Quality (CMAQ) version 4.5 with local perspective. Additionally, the nudging analysis for winds was adopted with three different coefficients to improve the wind fields in the complex terrain at 4-km grid resolution. The simulations focused on complex terrain having valley and mountain areas for ozone SIPs (State Implementation Plans). The ETA M-Y (Mellor-Yamada) and G-S (Gayno-Seaman) PBL schemes were identified as favorite options and promote O3 formation causing the higher temperature, slower winds, and lower mixing height among sensitivity simulations in the area of study. It was found that PX simulation did not always give optimal meteorological and CMAQ model performances at mountain sites. The results of nudging analysis for winds with three different increased coefficients’ values (2.5, 4.5, and 6.0 x 10-4 per second) over seven sensitivity simulations show that the meteorological model performance was enhanced due to improved wind fields, indicating the FDDA (Four Dimensional Data Assimilation) nudging analysis can improve model performance considerably at 4-km grid resolution. Specifically, the sensitivity simulations with the coefficient value (6.0 x 10–4) yielded more substantial improvements than with the other values (2.5 and 4.5 x 10-4). Hence, choosing the nudging coefficient of 6.0 x 10-4 per second for winds in MM5 may be the best choice to improve wind fields as an input, as well as, better model performance of CMAQ in the complex terrain area. The sensitivity of RRFs (Relative Response Factors) to the PBL scheme may be considerably significant with about 1-3 ppb in difference in determining whether the attainment test is passed or failed. Finally, a finer grid resolution was necessary to evaluate and access of CMAQ results for giving a detailed representation of meteorological and chemical processes in the regulatory modeling.

A ground-based, zenith-sky, UV-visible triple grating spectrometer was installed at the Polar Environment Atmospheric Research Laboratory (PEARL) in the Canadian High Arctic during polar springtime from 2004 to 2007 as part of the Canadian Arctic ACE (Atmospheric Chemistry Experiment) Validation Campaigns. From the solar spectra, ozone, NO2, and BrO vertical column densities (VCDs) have been retrieved using the DOAS (Differential Optical Absorption Spectroscopy) technique. This spectrometer, the UT-GBS (University of Toronto Ground-Based Spectrometer), was also deployed as part of the fourth Middle Atmosphere Nitrogen TRend Assessment (MANTRA) campaign in Vanscoy, Saskatchewan in August and September 2004. A near-identical spectrometer, the PEARL-GBS, was permanently installed at PEARL in August 2006 as part of the refurbishment of the laboratory by CANDAC (Canadian Network for the Detection of Atmospheric Change). Since then, the instrument has been making continuous measurements, with the exception of during polar night. Vertical columns of ozone and NO2 can be retrieved year-round. During the 2007 sunrise campaign, differential slant column densities (DSCDs) of OClO and VCDs of BrO were also retrieved. Ozone and NO2 DSCDs and VCDs from the UT-GBS were compared to the DSCDs and VCDs from three other UV-visible, ground-based, grating spectrometers that also participated in the MANTRA and Eureka campaigns. Two methods developed by the UV-visible Working Group of the NDACC (Network for the Detection of Atmospheric Composition Change) were followed. During MANTRA, the instruments were found to partially meet the NDACC standards. The comparisons from Eureka were an improvement on the MANTRA comparisons, and also partially met the NDACC standards. In 2007, the columns from the UT-GBS and PEARL-GBS were compared, and were found to agree within the NDACC standards for both species. Ozone and NO2 VCDs from the ground-based instruments were also compared to integrated partial columns from the ACE-FTS (ACE-Fourier Transform Spectrometer) and ACE-MAESTRO (ACE-Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) on board the ACE satellite. ACE-FTS partial columns were found to agree with the ground-based total columns, while the ACE-MAESTRO partial columns were found to be smaller than expected for ozone and larger than expected for NO2.

A groundbased instrument to measure the Atmospheric airglow of the molecular oxygen infrared atmospheric band emission was designed, built, tested and operated. The two channel photometer constructed was based on the original design by Evans (1967) that had been used in balloon experiments. The two channel photometer system specifications are presented. The major difference between the presented design and the earlier two channel photometers is the detector. An Indium Gallium Arsenide (InGaAs) photodiode provided better signal to noise in the conversion of the infrared light signal to an electronic signal than the previously used Lead Sulphide (PbS) detectors. The completed instrument was tested to determine its performance characteristics. Through these tests it was found that the photometer output offset is sensitive to ambient temperature fluctuations. An analysis of the instrument noise was done in an attempt to explain this sensitivity. The output noise performance was characterized and is presented together with the absolute brightness and wavelength calibrations. Data was collected with the instrument in Saskatoon, SK and Eureka, NU. After an initial observation campaign in the high arctic (Eureka, NU) modifications were made to the environmental housing of the instrument in order to improve the scientific value of the data collected. The collected data was processed and a simple analysis performed to demonstrate the capability of the photometer to measure the infrared atmospheric airglow. The collected data can be used to determine the mesospheric ozone height profile. The required data analysis to do so is beyond the scope of this presentation. However, the presented data does demonstrate that the designed and constructed two channel photometer can make the necessary measurements.

Measurements by OSIRIS, an infrared imaging system that measures emission from excited-state molecular oxygen, are used to retrieve mesospheric ozone through a photochemical model. The design of the model and the spectral data used in the calculation of pho- tochemical production coe±cients are presented. The model has been run in a variety of modes to provide comparisons with measurements of excited-state molec- ular oxygen; it has been found that the model results are in excellent agreement with measurements. The model is used in conjunction with a retrieval scheme to estimate the con- centrations of mesospheric ozone from measurements made on a satellite platform. An analysis of the sensitivity of retrieved ozone to key model parameters is done, and it is shown that uncertainty in several kinetic reaction rates can signi¯cantly change the retrieved results. Comparisons are made for the ozone retrieved in this work and that from several other instruments that make similar measurements. The retrieved concentrations are shown to be in excellent agreement with results from other instruments. The present work provides a climatological database of mesospheric ozone and will provide useful comparisons with concurrent measurements of mesospheric ozone. The new data obtained in this work are in good agreement with expected results, and it is shown that the unprecedented high-spatial resolution of OSIRIS reveals interesting features that should be further investigated.

AbstractThe bactericidal effect of ozone at concentrations of 1 and 2 p.p.m. by volume, was tested on separately atmized resting cell suspensions of Aerobacter aerogenes, Bacillus megathreium, and Escherichia coli B impinged on Millipore filters. The exposure of each species required the use of 18 randomly selected filters containing impinged organisms. Of the 18 filters, 6 were used in the control. The temperature and the relative humidity of the ozone flow were approximately 25ºC and 20 per cent, respectively, while the flow-rate across each filter was 3 liters per minute. It was found that all of the organisms tested were completely destroyed by both 2 and 2 p.p.m. ozone within 2 minutes of exposure.Ball State UniversityMuncie, IN 47306

When modelling pollutants in the atmosphere, it is nearly impossible to get perfect results as the chemical and mechanical processes that govern pollutant concentrations are complex. Results are dependent on the quality of the meteorological input as well as the emissions inventory used to run the model. Also, models cannot currently take every process into consideration. Therefore, the model may get results that are close to, or show the general trend of the observed values, but are not perfect. However, due to the lack of observation stations, the resolution of the observational data is poor. Furthermore, the chemistry over large bodies of water is different from land chemistry, and in North America, there are no stations located over the great lakes or the ocean. Consequently, the observed values cannot accurately cover these regions. Therefore, we have combined model output and observational data when studying ozone concentrations in north eastern North America. We did this by correcting model output at observational sites with local data. We then interpolated those corrections across the model grid, using a Kriging procedure, to produce results that have the resolution of model results with the local accuracy of the observed values. Results showed that the corrected model output is much improved over either model results or observed values alone. This improvement was observed both for sites that were used in the correction process as well as sites that were omitted from the correction process.
