Coronavirus: Important notice (Mars 17, 2020)
Due to current COVID-19 lockdown in France, ICARE Data and Services Center will be operated by teleworking only beginning March 16, 2020. Data services will keep running on a best effort basis. Some delays in resolving technical incidents and processing users requests may be expected.
Information regarding this situation will be posted on our covid-19-lockdown page. Thank you for your understanding.

ICARE

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. ICARE is one of the 4 centers of AERIS, the French Data Infrastructure for Atmosphere created in 2014.

Satellite images reveal the extent of Australia's wildfires

Australia was hit by a catastrophic fire season with massive wildfires torching the country from September 2019 to February 2020. The devastating fires posed severe safety and environmental problems, killing at least 33 people and an estimated 1 billion animals, and destroyed thousands of buildings and millions of hectares of land. Besides damages on the ground, the wildfire emitted important quantity of particles in the atmosphere, which caused widespread air quality issues for extended periods. The smoke was so abundant that it reached unusual heights in the atmosphere and even traveled around the world.

Release of CALIPSO IIR V4.20 L2 Product
April 2020

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center and the French AERIS/ICARE Data and Services Center in Lille, France, in collaboration with the CALIPSO mission team announce the release of a new version of the CALIPSO IIR Level-2 Track and Swath products.
The V4.20 IIR Level-2 track and swath data products are the first major revision to the products since Version 3 released in May 2011. They are named after the V4.20 CALIOP 5-km cloud and aerosol layer data products, which are used in synergy with the IIR calibrated radiances reported in the V2.00 IIR Level-1 data product. The V4.20 IIR Level-2 data products include a refined CALIOP-based scene classification, an updated radiative transfer model analysis for clear air reference, improved optical and microphysical properties of ice and water clouds, both over ocean and over land, in particular for thin clouds and for multi-layered cloud systems.
The products released are available in the ICARE archive and on the new ASDC site:



New insights into cloud microphysical processes from combined POLDER-MODIS Level-2 observations "PM-L2" – March 2020


202003_PM-L2/Illustration_VanDiedenhovenCoopman.png

New insights into cloud microphysical processes were inferred from the combined POLDER-MODIS dataset developed by LOA and produced and distributed by AERIS/ICARE. Two recent studies investigated cloud microphysical processes that are critical to understand for a correct representation of cloud feedback in numerical weather and climate models. The results are detailed in two recent papers using the PM-L2 Version 3.00 data sets globally. (click here for details).



Release of CALIPSO LIDAR Level-3 GEWEX Cloud Standard Product
December 2019


calipso_expedited/Logo_Calipso.jpg

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center and the French AERIS/ICARE Data and Services Center in Lille, France, in collaboration with the CALIPSO mission team announce the release of a new CALIPSO lidar level-3 (L3) Global Energy and Water cycle Experiment (GEWEX) Cloud product. This new data product is a reformatted version of CALIPSO's contribution to the GEWEX cloud assessment of global cloud datasets from satellites (https://climserv.ipsl.polytechnique.fr/gewexca/index.html).

The data submitted by the CALIPSO team for this project had to conform to a very specific format; yearly netCDF files organized by parameter. In order to be compatible with other publicly orderable lidar L3 CALIPSO aerosol and cloud products, which are reported as monthly HDF files, this new lidar L3 CALIPSO GEWEX cloud product was created. These files report global distributions of cloud amount and cloud top as averages and histograms on a uniform 2-dimentional (2D) spatial grid. All level-3 parameters are derived from the CALIPSO version 4.x level-2 5 km cloud merged layer products, with a temporal averaging of one month.

CAL_LID_L3_GEWEX_Cloud-Standard-V1-00 DOI: 10.5067/CALIOP/CALIPSO/LID_L3_GEWEX_Cloud-Standard-V1-00

The monthly products are available beginning with data from June 2006 through December 2016.
