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.

HIGHLIGHTS


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 algorithm, 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.




Release of CALIPSO V4-10 Level-1 and Level-2 Lidar products
November 2016 – Updated March 2017

Update of previous highlight posted in November 2016.
The CALIPSO mission announces the release of new versions of its standard Level-1 and Level-2 lidar data products. These products are available through the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center and the French AERIS/ICARE Data and Services Center in Lille, France. The new data products consist of the Version 4.10 Lidar Level-1 Products and Version 4.10 Lidar Level-2 Products. The V4.10 CALIOP Level 2 data products are the first major revision to the Level 2 product suite since May 2010. The extensive improvements made in this new release correct numerous artifacts and significantly enhance the content and quality of the science data. In addition to the substantial updates made to all existing Level 2 products, V4.10 introduces a new merged layer product that reports the spatial and optical properties of cloud and aerosol layers in a single file.
Users are instructed not to use Version 4.00 Lidar Level 1 product any longer and to use instead the Version 4.10 for science use. The product is available beginning with data from June 13, 2006 (following CALIOP first light), and as of this update, through July 31, 2016. Remaining data will be available as it is produced. The product is now available on all currently existing standard order tools as well as the CALIPSO Search/Sub-setter application.
Version 4.00 Lidar Level 1 will be deleted from the AERIS/ICARE archive in a couple of months.

The 705-km Afternoon (A-Train) Satellite Constellation brings together a rich array of instruments to better understand Earth’s changing climate and environment. The 3rd International Symposium on the A-Train Satellite Constellation is an opportunity to learn more about the evolving capabilities of the A-Train system, and to engage other colleagues with similar interests.
To see the second official circular, click here.
Registration and abstract submission are now open. The deadline for abstract submission has been extended to December 16, 2016. There is no registration fee to attend. Additional information regarding the meeting is available on the symposium web site: https://atrain2017.org/
