What's the difference to CarbonTracker(CT)-Asia for CT-North America(NAM)?
CT-Asia uses a nested grid to provide enhanced transport resolution over Asia instead of over North America (NAM).
Vertical diffusion scheme of CT-Asia has been changed to YSU PBL scheme. YSU has greater vertical mixing, diffusing CO2 in the PBL instead of trapping it in the surface layer.
CT-Asia uses Japan Meteorological Agency (JMA) CO2 observations which were not assimilated in CT-NAM.
