- About us
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:
Release of SEVIRI AERUS-GEO aerosol product – January 2015
MSG/SEVIRI AERUS AOD 0.63 µm observed by SEVIRI
Image credit: CNRM-GAME/ICARE.
A new SEVIRI aerosol product has been developed in the framework of a joint collaboration between Meteo France (CNRM-GAME) and ICARE. The new daily (daytime) aerosol optical depth product (SEV_AERUS-AEROSOL-NRT-D3) is public (click here to access the data from the archive interface (current version: v1.01, year 2014 until present)).
The AERUS-GEO (Aerosol and surface albEdo Retrieval Using a directional Splitting method-application to GEOstationary data) product is derived from observations from the Meteosat Second Generation (MSG) geostationary satellite covering Europe, Africa, and part of Asia and South America. The retrieval method exploits the directional information contained in the series of 96 MSG observations per day of the Earth’s disk to derive a daily mean AOD and an Angström exponent. Detailed description of the algorithm and evaluation studies are available in Carrer et al. 2010 (JGR) and Carrer el al., 2014 (see Publications). A reprocessing of the whole SEVIRI archive (2004-present) will be available soon.
2e atelier TRATTORIA: "Transfert Radiatif
dans les ATmosphères Terrestres pour les ObseRvations spatIAles"
2nd workshop on "Radiative transfer in the atmosphere for spatial observations”
23-25 March, 2015, Polytech’Lille, University of Lille 1
Le CNES organise, avec l’Université Lille 1, la seconde édition du workshop TRATTORIA. Cet atelier sur les codes de transfert radiatif atmosphérique sera l’occasion de dresser un panorama des codes utilisés dans les différentes communautés scientifiques françaises et de discuter des évolutions attendues pour les prochaines années, particulièrement pour les missions spatiales d’observation de la Terre. A la suite de tables rondes thématiques, des recommandations seront émises pour orienter les travaux futurs autour des codes de transfert radiatif. Cet atelier se déroulera du 23 au 25 mars 2015 à Polytech’Lille, à l’Université Lille 1. Les inscriptions sont gratuites, mais le nombre de participants est limité à 100.
The CNES and the University of Lille 1 are organizing the second workshop on Radiative transfer codes in the atmosphere. It will be held at the University of Lille 1, 23-25 March, 2015. The aim of the workshop is to provide an overview of the radiative codes used by the French science community, to foster exchanges between research scientists from multiple disciplines and to discuss perspectives for the coming years regarding spatial remote sensing. Registration to the workshop is free but seating is limited.
CALIOP V4 Level-1 Product Release
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 data product: CAL_LID_L1-Standard-V4-00
This updated version of the CALIOP Level-1 data product substantially improves both the 532nm and 1064nm calibration accuracies. Changes to the calibration techniques were firmly rooted by a thoroughly documented and peer-reviewed approach.
The version 3.x (3.01, 3.02 and 3.30) CALIOP Level-1 data product will continue to be generated and made publically available, with version 4.0 running in parallel. Unlike version 3.x, which is released continuously following 2-3 day latency from downlink, new releases of the version 4.0 product will be made periodically in discrete blocks.
The product is available beginning with data from June 13, 2006 (following CALIOP first light), and as of this announcement, through December 31, 2013. Remaining data will be available as it is produced.
