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.




Release of CALIPSO V4.20 Lidar Level 2 products
October 2018


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 an update to the standard Level 2 lidar data products:

  • CAL_LID_L2_01kmCLay-Standard-V4-20
  • CAL_LID_L2_333mMLay-Standard-V4-20
  • CAL_LID_L2_05kmMLay-Standard-V4-20
  • CAL_LID_L2_05kmALay-Standard-V4-20
  • CAL_LID_L2_05kmCLay-Standard-V4-20
  • CAL_LID_L2_05kmAPro-Standard-V4-20
  • CAL_LID_L2_05kmCPro-Standard-V4-20
  • CAL_LID_L2_VFM-Standard-V4-20
The V4.20 CALIOP Level 2 products contain new laser energy science data sets. These science data sets provide information for filtering out low laser energy shots, a phenomenon which has impacted CALIOP data quality in the South Atlantic Anomaly region since mid-2017. A technical advisory of this phenomenon, and the recommended courses of action for mitigating its impact on science analyses, was posted on the CALIPSO website in June of 2018. In that advisory, it was noted that the existing V4.10 CALIOP Level 2 dataset did not contain enough information to identify low laser energy shots without having to access the corresponding V4.10 CALIOP Level 1 files. In order to provide a simpler method to exclude affected level 2 data, the new V4.20 CALIOP Level 2 files now includes science data sets for both 532 nm single shot energy (directly from the Level 1 product) and the minimum 532 nm laser energy for each 80 km chunk. This avoids the necessity to download both the CALIOP Level 1 and Level 2 data products in order to exclude affected profiles. All other science data sets within the V4.20 Level 2 products are identical to those of the V4.10 Level 2 products.
The product is available beginning with data from January 1, 2017 and as of this announcement, through May 31, 2018. Remaining data will be available as it is produced, starting with most recent and working backwards through the mission.




CALIPSO orbit change
September 2018


calipso_expedited/Logo_Calipso.jpg

On September 13, 2018 CALIPSO will begin lowering its orbit from 705 km to 688 km to resume formation flying with CloudSat. The sequence of maneuvers is expected to take about a week and the payload instruments will be turned off (Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC)). Normal science operations are anticipated to begin in late September with public data availability around October 10, 2018.

First announcement
2nd Workshop CGMS International Cloud Working Group
29 October-2 November 2018, Madison, Wisconsin, USA


workshop_2018_first_announcement/madison.jpg

The 2nd Workshop of the International Cloud Working Group (ICWG) will be held in Madison, Wisconsin, USA from 29 October to 2 November 2018. The workshop aims at enhancing cloud retrieval schemes and their applicability and a better characterization of their validity. Experts working with cloud parameter retrieval schemes from passive imagers, passive microwave, and lidar and radar observations are invited to participate in the workshop and to contribute to the workshop’s cloud parameter inter-comparison and validation activities. More information on registration and submitting abstracts will follow in the second announcement.

Release of CALIPSO V1-00 Lidar Level-3 Ice Cloud product
July 2018


calipso_expedited/Logo_Calipso.jpg

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission team announces the release of a new CALIOP Level 3 Ice Cloud Product: CAL_LID_L3_Ice_Cloud-Standard-V1-00
The CALIOP Level-3 Ice Cloud monthly product reports global distributions of ice cloud extinction coefficients and ice water content histograms on a uniform spatial grid. All parameters are derived from the latest version 4 CALIOP Level-2 5 km cloud profile product. The monthly product is available beginning with data from June 13, 2006 through December 31, 2016.

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


calipso_expedited/Logo_Calipso.jpg

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.




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.
