README -- Describes contents of HEMCO/CEDS/v2023-04 directory
6 Apr 2023


Overview:
==============================================================================

Global anthropogenic emissions from the Community Emissions Data System (CEDS)
inventory. Emission species include aerosol (BC, OC) and aerosol precursor and
reactive compounds (SO2, NO, N2O, NH3, CH4, CO, NMVOC) and CO2.

For more information see the CEDS wiki:

   https://github.com/JGCRI/CEDS/wiki

Original data were downloaded from

   https://data.pnnl.gov/group/nodes/dataset/13488

and were processed for GEOS-Chem. The processing scripts can be found in the
scripts/ subdirectory. 

Notes:
===============================================================================
Original NOx emissions from CEDS have been converted to NO
