The ICARE Thematic Center was created in 2003 by CNES, CNRS, the Nord-Pas-De-Calais Regional Council, and the University of Lille, to provide various services to support the research community in fields related to atmospheric research, such as aerosols, clouds, radiation, water cycle, and their interactions. ICARE's initial emphasis is the production and distribution of remote sensing data derived from Earth observation missions from CNES, NASA, and EUMETSAT. One of ICARE's main components is the Data and Services Center, located at the University of Lille, which develops science algorithms and production codes, building on the expertise from various partner Science Computing Facilities, and distributes products to the users community.


New product announcement – October 2014
MODIS-like SEVIRI cloud product:
public beta release for evaluation purposes

A new SEVIRI cloud product has been developed in the framework of a joint project between scientists and data experts from NASA, NOAA, LOA, and ICARE. This new dataset, called SEV06-CLD, is derived from the MSG/SEVIRI instrument observations using an algorithm that replicates the retrieval core of the Collection 6 MODIS Level-2 cloud product (MOD06_L2 and MYD06_L2) augmented with NOAA GOES-R cloud height product. Moreover, several ancillary datasets are used to produce SEV06-CLD including the SAFNWC cloud type product.

The project team is pleased to announce the public release of the SEVIRI SEV06-CLD beta product at ICARE for evaluation purposes. Users are invited to provide feedback and comments on product quality.

For detailed information on the product, data access and availability, and data use restrictions, please refer to the SEV06-CLD Cloud Product Technical Document. More information will soon be available on the ICARE web site.

PARASOL Level-1 and Level-2 data reprocessing underway
September 2014


The PARASOL Level-1 data and all atmosphere products are currently being reprocessed from the beginning of the mission onward using revised algorithms. The Level-1 reprocessing, performed by CNES, began in April 2014 and new files are transferred to ICARE for Level-2-and-up products reprocessing. As of September 1, 2014, PARASOL data from March 2005 to mid-2008 are available at ICARE. The reprocessing of the whole PARASOL archive (until October 2013) is expected to be completed by the end of 2014.
Changes to the Level-1 algorithm include improved radiometric calibration. For aerosol products over ocean, changes include the calculation of uncertainties, improvement of aerosol non-spherical models and cloud mask, and the implementation of a sea-ice mask. Over land, changes include the use of a higher resolution land biome map and the retrieval of the altitude of the aerosol layer. For cloud and radiative budget products, the solar irradiance was updated.

Data services related to PARASOL will switch to the latest version of all products (L1_B.v03.02, OC2.v11.11, LS2.v10.11) when the reprocessing is complete.

1st circular
3rd International A-Train Symposium
Southern California
Postponed to a later date to be determined (originally scheduled 4-6 March 2015)


The A-Train is now celebrating its 8th anniversary. The 3rd International A-Train Symposium will be an opportunity to learn more about A-Train scientific breakthroughs and to highlight how Earth science has benefitted from multi-sensor data and the growing length of the data records. The 3rd Symposium follows on previous A-Train Symposia held in Lille, France in 2007 and in New Orleans in 2010. The Symposium will provide a forum for exchanging information on the latest scientific advancements made possible by multi-sensor measurements.
