New parameters in dissemination
Mass density of air
At the moment almost all of the chemical and aerosol species we disseminate and archive are expressed as mass mixing ratios. While this might be sufficient for most of the users, some would prefer to use mass concentration values.
The conversion formula is simple and we are now providing air density as a new parameter in the CAMS global dissemination streams (CAMS_NREALTIME/CAMS_GLOBAL). The parameter is available on pressure and model levels in both GRIB and NetCDF format. The new files are named as follows:
