README -- describes contents of CAC_200801 directory 31 Jul 2013 GEOS-Chem Support Team geos-chem-support@g.harvard.edu bpch files: ----------- CanadaMask.geos.1x1 : Geographic mask to define Canada region CAC2002-CO.geos.1x1 : Anthro CO emissions [kg/yr], base year 2002 CAC2002-NH3.geos.1x1 : Anthro NH3 emissions [kg/yr], base year 2002 CAC2002-NOx.geos.1x1 : Anthro NOx emissions [kg/yr], base year 2002 CAC2002-SO2.geos.1x1 : Anthro SO2 emissions [kg/yr], base year 2002 CAC2005-CO.geos.1x1 : Anthro CO emissions [kg/yr], base year 2005 CAC2005-NH3.geos.1x1 : Anthro NH3 emissions [kg/yr], base year 2005 CAC2005-NOx.geos.1x1 : Anthro NOx emissions [kg/yr], base year 2005 CAC2005-SO2.geos.1x1 : Anthro SO2 emissions [kg/yr], base year 2005 Original Data Files: -------------------- CAC emission data files (bpch format) were put together by Aaron van Donkelaar. Emissions are all placed on the global 1x1 GEOS-Chem grid. Source data : see http://www.ec.gc.ca/pdb/cac/cac_home_e.cfm Bob Yantosca (yantosca@seas.harvard.edu) maintains the archive of the files obtained from Aaron van Donkelaar. The netCDF files were created from these bpch files with IDL routine "make_cac_nc.pro" (which is simply a wrapper for GAMAP routine "bpch2coards.pro". NOTES: ------ (1) The NH3 data files in this directory are superseded by the NH3 data files in ../CAC_201307. The NH3 data files in this directory have have a bug that that prevents NH3 from varying with season. -- Bob Yantosca, 31 Jul 2013
