Re: Number Concentration from MERRA-2

Hello,

This is the reply from our MERRA-2 data team:
"The current MERRA-2 aerosol model doesn’t include aerosol-cloud interactions, and thus doesn’t produce the parameters such as the aerosol number concentrations."

Re: Magnitude and Unit of PM2.5, MERRA-2: Conversion Necessary?

From our data specialist: "I am glad that my previous response was helpful. The MERRA-2 reanalysis, including aerosol reanalysis, is not pure observation. It results from assimilating various observations into a model, i.e., the NASA GEOS model. Thus, you can use PM2.5 from the dataset M2TMNXAE...
