Hot spot of PM2.5 in Kansas

Hi All,
I run WRF/Chem with NEI 2017 processed by SMOKE with the default setting. A PM2.5 hot spot (red circle on the figure) in Kansas in April 2017 confused me a lot. Do you have any suggestions or assumptions about how it could happen? Thanks so much.

This is in Kansas. They have prescribed burning of grasslands every April.


Hi Alison, Thanks so much for helping me out with this. :grinning:
