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.

CALIPSO IIR Level-1 V2-00 Release Announcement
July 2017

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission announces the release of the following data product: CAL_IIR_L1- Standard-V2-00
Version 2.00 of the IIR Level-1 product is the first major revision since the initial release in 2006. The calibration procedure has been adjusted to reduce known small seasonal calibration biases in the Northern Hemisphere, which were caused by thermal drifts synchronized with the elapsed time since the night-to-day transition. The product is available from June 13, 2006 to current. The Version 1 standard and expedited data products will continue to be generated and provided to the public. There is no expedited version of the V2.00 IIR Level-1 planned for this release.

We are pleased to announce the release of the daily cumulated surface rainfall products and associated uncertainties. This so-called TAPEER-BRAIN product is available for the period from October 2011 till end of December 2016 at the resolution of 1°/1day, and are archived at the AERIS/ICARE data center.
To access the data, users must register. Registered users can access the data through the Archive Web Interface and the FTP server. See the Data Access section for details on access procedures and data policy.

POLDER/PARASOL full reprocessing and
new multi-sensor synergistic products – April 2017


symposium_2017_first_announcement/PARASOL_product_suite_600.png

At the end of the PARASOL mission, CNES completed the final reprocessing of Level-1 data in 2014. ICARE completed the reprocessing of the PARASOL Level-2 and Level-3 products in 2015, using revised science codes as well as new codes provided by the French science team at LOA (University of Lille).
In addition to the HDF5 version of the products, released in 2016, global gridded Level-2 and Level-3 products are also available now in HDF5 format.
The Level-2 and Level-3 products are generated from the Level-1 data alone or in combination with other data sets. PARASOL stand-alone products include the Level-2 and Level-3 data sets and the PARASOL "CALTRACK" product (subset colocated with the CALIPSO/CALIOP subtrack).
More recently, an innovative !lgorIthl, called "GRASP" (Generalized Retrieval of Aerosol and Surface Properties), has been developed to retrieve simultaneously many more parameters compared to the standard product. Finally, the unique synergistic "PM-L2” Level-2 product is derived from combined PARASOL and Aqua/MODIS observations.
