ICARE Highlights



Release of CALIPSO IIR V4.20 L2 Product
April 2020


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 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.



Release of SODA V2-20 and V2-21 products
January 2020


calipso_expedited/Logo_Calipso.jpg

AERIS/ICARE is pleased to announce the release of the latest version of the CALIPSO/CloudSat SODA products, giving access to the aerosol and semi-transparent cloud optical depths from the analysis of surface and dense clouds returns. This product originates from the collaboration between IPSL/LATMOS, NASA LaRC, and AERIS/ICARE Data and Services Center. The whole CALIPSO/CLOUDSAT period has been reprocessed.
This version uses the latest version of the algorithm (v2.3.0) and the latest input data available at the moment (CALIOP level 1 V4-10 and level 2 V4-20, CLOUDSAT R05, MODIS C6, ASMR_E v7, AMSR2 v8). The difference between the V2-20 and V2-21 versions comes from the AMSR data used:

  • For V2-20: AMSR_E from 2006-06-15 to 2012-06-30
  • For V2-21: AMSR2 since 2012-07-01
Please note that for the 2011-11-04 to 2012_07_01 period, there is no AMSR data available.
A full documentation will be available soon.



CATS L1B V3-00 and L2O V3-01 data products available
July 2019


201907_cats/cats-logo-150px.png

NASA’s Cloud-Aerosol Transport System (CATS) is a lidar remote sensing instrument on the International Space Station (ISS). During its life span of 33 months, from 25 March 2015 through 29 October 2017, CATS provided measurements of cloud and aerosol profiles similar to CALIPSO.
CATS Level-1B Version 3-00 and Level-2O Version 3-01 data are now available both in the ICARE archive and at NASA/ASDC.

Workshop announcement:
International Satellite Cloud Climatology Project ­– Next Generation
EUMETSAT, 28-30 October 2019 (invitation only)


workshop_201910_ISCCP/ISCCP.png

The workshop will be held to discuss priorities for the future direction of the International Satellite Cloud Climatology Project ­– Next Generation (ISCCP-NG). The Earth observing capabilities from geostationary orbit have advanced substantially over recent years. With the launch of GOES-17 in 2018, the global geostationary constellation is now comprised of sensors with 10 or more channels, viewing the earth at sub-hourly time scales and with resolutions finer than 5 km. With the launch of Meteosat Third Generation (MTG) in 2021, the global geostationary constellation will have 10 common spectral channels. There is a clear need to exploit this new Earth observing capability. The primary goal of the workshop is to define the scientific scope and the technical contents and methods needed for ISCCP-NG.
The registration deadline is September 30, 2019.



Release of CALIOP V1-00 Level 1.5 product
April 2019


calipso_expedited/Logo_Calipso.jpg

The CALIPSO mission team, in collaboration with the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center and AERIS/ICARE Data and Services Center, announces the release of a new CALIOP Level 1.5 Product:
CAL_LID_L15-Standard-V1-00
The CALIOP Level 1.5 data is a continuous segment of calibrated, geo-located, cloud-cleared, and spatially averaged profiles of lidar attenuated backscatter. These profiles are derived via a synthesis of the CALIOP V4.10 Level 1B profile and V4.20 Level 2 Vertical Feature Mask data products.
The product is available beginning with data from June 13, 2006 and as of this announcement, through December 31, 2018.

Order tool for geostationary data
October 2018


201810_order_interface_geo/order_tool_400.png

A new order tool was developed by AERIS/ICARE Data and Services Center to retrieve geostationary data sets from the ICARE archive.
Click here to access the tool.
Users can combine various selection criteria (satellite(s), data set(s), geographic region, date range, time range, etc.) to place custom orders. Orders can mix different satellites and data sets. Reprojection on a standard geographic grid is offered as an option, along with geographic subsetting. The tool generates a download script based on the users selection, such that users can retrieve complex and/or massive orders offline automatically. The service is open to all registered users.
Users are invited to provide feedback and comments to contact@icare.univ-lille1.fr.
