Deposition data

Should total MERRA-2 black-carbon surface deposition be calculated from four variables (BCDP001/002 + BCWT001/002), or should BCSD001/002 sedimentation also be included, and would including them cause double counting?

Dear User,

Here is a response from the GMAO team:

Total loss = BCDP001 + BCDP002 + BCSD001 + BCSD002 + BCWT001 + BCWT002 + BCSV001 + BCSV002.

Nothing is double counted by using all of the terms in this equation for the total loss.

IS deposition equivalent to total loss ?
isnt total loss means total removal of the particles from the environment
and deposition mean the actual presence of particles on the surface of the glacier/land ?

Dear user,

The previous equation sent should be considered as the total loss of the aerosols from the atmosphere to the surface. In the real world, there could be a loss in aerosol due to chemical processes however that isn't accounted for in the model.
