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.
