Note: this dataset is generated as part of the ESA GHG-CCI project and is still under validation.
The retrievals are performed between 60°S and 70°N.
Important information for the users
When comparing the IASI CH4 or aerosol product with a high resolution profile (aircraft profiles, model data, lidar profile..), the sensitivity of the (low resolution) IASI profiles needs to be taken into account.
This can be done by smoothing the high resolution profile with the IASI averaging kernel :
: the smoothed (aircraft or model) profile
: the IASI CH4 a priori profile
: the IASI CH4 averaging kernel
: the high resolution (aircraft or model) profile
Note, the averaging kernel is given in vmr/vmr units.
The IASI dust aerosol product is also available through the Copernicus Climate Data Store, in a limited version containing the dust AOD and the dust mean altitude as daily and monthly averages (level 3 data). To access that product, use the link here above then in the "download data" section, algorithm subsection, select "MAPIR (Mineral Aerosol Profiling from thermal Infrared Radiances)". Then only the other selections compatible with that choice will be available. The interested user will also see other dust aerosols product in the Climate Data Store.
