| Abstract | Sulfur budget estimation for Bangkok was assessed in this study through the source, deposition and transboundary fluxes of sulfur in the area for the year 2000. The box model and ATMOS2 were applied to simulate the atmospheric concentration and deposition of sulfur within the modeling domain which covers BMR and nearby provinces. The SO2 emission data were taken from The University of Iowa. The meteorological data were obtained from the NOAA-Climate Diagnostics Center in netCDF/IOAPI reanalysis format. ATMOS was calibrated appropriately to calculate the atmospheric concentration and total deposition from all sources in the domain with the estimated boundary conditions. Model performance was evaluated by comparison between model outputs of SO2 concentration and sulfate wet deposition with the corresponding monitoring data at the thirteen SO2 monitoring stations and three wet deposition observation sites. The performance criterions include the temporal, spatial distribution and correlation coefficient between the simulated and observed values. Even though, the correlation between the gridded average monitoring data and the model output was not high, the model outputs are agreed reasonably with the monitoring data according to time series analysis and the spatial distribution. The maximum annual average concentration of SO2 and SO42- were 11 and 5 g/m3, while the maximum wet and dry deposition were 716 and 208 mgS/m2/year, respectively. Both the highest SO2 concentration and sulfur deposition were obtained in the Bangkok center. The most deposition in Bangkok was a consequence of the emission in the city itself. The budget calculation has shown that Bangkok is the significant source of sulfur transported to the vicinity area. The sulfur budget estimation also provides the information of sulfur fluxes within Bangkok for development of sulfur deposition management strategies. |
