Concentration Grid Size Sensitivity

Load captex_control.txt and captex_setup.txt
Change the grid size to 0.05 and name output file captex2fg.bin
and then run the simulation


Extract the time series at Little Valley, NY


Create the statistical output

Although the statistical metrics showed that the fine grid simulation was similar to the coarse grid simulation, the time series at Little Valley showed much lower concentrations than were measured.

Alternate approach edit and run the batch files:
conc_cexp.bat, conc_util.bat, and conc_stat.bat


Extract the time series at Little Valley, NY


At this location, using the 9 km meteorology showed a much better fit with the measured time series as well as a slight improvement in the overall statistical results.
