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.
Release of CALIPSO Lidar Level-2
Polar Stratospheric Cloud (PSC) data product
The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission team announces the release of a new data product CAL_LID_L2_PSCMask-Prov-V1-00
This new ensemble CALIPSO Lidar Level-2 Polar Stratospheric Cloud (PSC) data product describes the spatial distribution and optical properties of PSC layers observed by the CALIPSO lidar. The product contains profiles of PSC presence, composition, optical properties, and meteorological information along CALIPSO orbit tracks. Data from all nighttime orbit segments from a single day are reported on a 5-km (horizontal) by 180-m (vertical) grid. This new product is available beginning with data date June 13, 2006 (start of the mission).
Release of standard and expedited IIR Level-2
Track and Swath data products
The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission team announces the release of the following standard and expedited data products:
Public release of Megha-Tropiques SAPHIR and ScaRaB Level-2 products
Update on Level-1 products and MADRAS status
- SAPHIR L2-UTH: Upper Tropospheric Relative Humidity from SAPHIR
- ScaRaB L2-FLUX: Top-of-the-Atmosphere shortwave and longwave unfiltered Radiances, Flux and Albedo products
- ScaRaB L2B-FLUX: 1-degree gridded version of the L2-FLUX shortwave and longwave Flux and Albedo products
Concerning the Level-1 products, the mission group has decided that orbit-wise products require further evaluation and should no longer be distributed to the public until further notice. The segment-wise Level-1 products are available in version 1.06.
Concerning MADRAS, ISRO and CNES announced in a joint communiqué in September 2013 that the MADRAS instrument has been declared non-operational. As of January 26, 2013, MADRAS Level-1 data is not valid and will not be disseminated to users. The 16-month archive of valid data (from launch to January 26, 2013) are currently restricted to the Science Team members and to other accredited users. MADRAS data are expected to be released in 2014.
