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

Fine Grid StatA results


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



All the statistical metrics showed that the fine grid simulation was inferior to the coarse grid simulation (e.g. correlation decreased from 0.67 to 0.47). The coarser grid compensated for random errors when model predictions are paired with observations in both space and time.
