We would like to inform you that the latest upgrade (U4) to the CAMS European air quality forecasts model has been implemented.
The main features introduced in the upgrade include:
1)Implementation of CAMS-REG emission including condensable PM (REF2) based on the reference year 2017.
2)Deletion and replacement of PM2.5 elemental carbon species.
The following parameters have been deleted:
Particulate matter d < 2.5 µm - anthropogenic fossil fuel carbon only
Particulate matter d < 2.5 µm - anthropogenic wood burning carbon only
The following two species have been added as replacements:
Particulate matter d < 2.5 µm - anthropogenic total carbon only
Particulate matter d < 2.5 µm - anthropogenic residential carbon only
3) Addition of Mugwort pollen for surface NRT forecasts.
The new source term consists of the addition in one parameter of 5 different Mugwort pollens, which cannot be clearly differentiated by observations.
Please see CAMS Regional: European air quality analysis and forecast for documentation

Your sincerely,
