How can I adjust black carbon surface mass air pollution concentrations (ug/m3) for rainfall effects?
Specifically, I have monthly and daily averaged black carbon pollution data (i.e. 2.0ug/m3 Jan 2016, Feb 2016, etc) obtained from MERRA-2 reanalysis dataset. I also have averaged monthly rainfall data (i.e. cm per month).
Generally, the air pollution decreases in the higher rainfall months and increases during dry months. I'm interested to remove the rainfall effect from the air pollution values. The end goal is to compare the different months to explore biomass burning effects.
Any suggestions would be greatly appreciated.
