Dear all, 

Does anyone know what happened with the 4km SMOKE output for NEI?

It becomes a myth that many people tell me it exist(ed) but they can't find it online either. If it was taken down for whatever reason, would it be possible for someone to share a copy with me?

Thanks a lot, 

Xinjie

Hi Xinjie

the NEI emissions we provide on our website are at 12 km resolution and I am not aware of where you could get 4km NEI emissions from. 
For higher spatial resolution you might want to check out the NOAA GRAPES (https://csl.noaa.gov/groups/csl4/gra2pes/) or the NEMO inventory (https://www.nature.com/articles/s41597-022-01790-9).
