> Hello, We have been trying to map the Fire emissions from prescribed burning and wildfires from the 2020 NEI files from July 01, 2020 to July 10, 2020. However we are not getting any emission data as every species (pm2.5, ch4, co, etc) of all the days mentioned above at all hours are zeros. Has anyone encountered issues with using NEI Fire emissions? Or did anyone work with these specific dates for prescribed burning and/or wildfires? Thank you!
