Dear all,

I want to extract the NOX emissions from soil surface from the BEIS sector’s emissions in the EPA’s 2020 emissions modeling platform. I notice that there are 286 land use categories contained in BELD4. Do you know which land use type should be considered as soil surface in BELD4? Much appreciated for your help!

Best wishes,
Lingyun
