Rich,

We're in the process of updating some of the data and a draft paper
describing it.

Attached is the draft as it is now.....

origin of BELD3 land use data?









Hi Chris,

As part of a regulatory impact analysis workshop last week, I was asked
about the "vintage" of the BELD3 land use data we used for biogenic
emissions.  Can you point me to a reference for this data?

From what I can tell. there is updated biogenics land use data (which we
were not aware of), as this BELD3 data appears to be 1990's in origin:

Any information you can send would be great.  Thanks!
