Assimilation in the CAMS project

http://www.gmes-atmosphere.eu/d/services/gac/nrt/nrt_fields/

IASI and MOPITT are currently both being assimilated to produce chemical forecasts of CO fields (Inness et al., 2013).

Atmosphere Monitoring

Long-range transport of Canadian wildfire emissions to Europe

• Long-range transport of wildfire CO emissions in the free troposphere (averaged between

approx. 3 and 8 km) from North America to Europe.

• CAMS analysis fields including assimilated CO observations from MOPITT and IASI.

IASI and IASI-NG time coverage

Depending on the way we treat the data : filtering or not, weigthed means or not, taking only morning or evening overpasses, results will be very different !

No filtering and regular averages following Van Damme et al. 2017 recommandations.

Filtering and weigted averages following Van Damme et al. 2014 recommandations.
