    CryoVEx 2016 Spring

    The CryoVEx 2016 campaign was primarily carried out to follow up on a recommendation given within ESA CryoVal Land Ice project (2014-2015), where it was found that the traditional under-flights of the CryoSat-2 satellite were inadequate.

    CryoVEx ASIRAS 2014

    The CryoVEx 2014 airborne campaign was conducted as two separate operational periods. The sea ice activities covering large parts of the western Arctic Ocean were planned to take place early in the season to make sure the weather was stable.

    CryoVEx ICESat-2 Summer 2019

    The ESA CryoVEx/ICESat‐2 summer campaign 2019 is an add‐on to the campaign carried out in the spring 2019, which did not cover all the flights that were planned due to weather obstacles.

    CryoVEx/KAREN Antarctica 2017/18

    ESA’s CryoVEx/Karen 2017‐18 campaign took place in Antarctica in from Dec 2017 to Jan 2018. The campaign was composed of an airborne and in‐situ campaign and acquired extensive data sets of scanning lidar, Ku‐ and Ka‐band nadir‐looking radar, and auxiliary imagery for validation of the ESA CryoSat‐2 satellite (Ku‐band radar altimetry) and the French‐Indian AltiKa mission (Ka‐band radar altimetry).

    CryoVEx KAREN 2016 Fall

    The CryoVEx-KAREN 2016 Fall Campaign in Ilulissat, Greenland had the goal to collect unique measurements to help us better understand how snow and ice on the Greenland ice sheet is changing over time, and help ESA design future space missions to monitor the changing climate in our polar regions.

    ERS-1/2 ATSR Averaged Surface Temperature [AT1/AT2_AR__2P]

    The Averaged Surface Temperature Product (AST) contains averaged geophysical data at two different resolutions, and with respect to two different averaging schemes: measurement data sets at resolutions of 0.5 by 0.5 degrees and 10 by 10 arcmin with respect to a latitude/longitude grid; other data sets contain data averaged over equal area cells of 50 by 50 km and 17 by 17 km aligned with the satellite ground track. Both top-of-atmosphere and surface data sets are provided. The surface temperature data sets provide, for sea cells, nadir and dual view sea surface temperatures, and for land cells, land surface temperature (currently 11 micron BT) and NDVI. Cloud data is also included. No ADS are included in the AST product; auxiliary data is contained within the MDS. The data sets of the AST product are arranged by surface type and resolution. The 3rd reprocessing of ATSR data was performed in 2013; the processing updates that have been put in place and the scientific improvements are outlined in full in the User Summary Note for the Third ERS ATSR Reprocessing.

    ERS-1/2 ATSR Meteo Product [AT1/AT2_MET_2P]

    The data is a fast delivery Meteo product designed for use by meteorological offices, and contains averaged BT and SST at 10 arc minute resolution. The single MDS comprises the fields of MDS#3 (SST record, 10 arc min cell) of the AST product, with the addition of Average Brightness Temperature (ABT) fields (BT/TOA sea record, 10 arc min cell) to make it more self-contained. The 3rd reprocessing of ATSR data was performed in 2013; the processing updates that have been put in place and the scientific improvements are outlined in full in the User Summary Note for the Third ERS ATSR Reprocessing.

    ERS-1/2 ATSR ARC L2P/L3U [UPA-L2P_GHRSST/L3U_GHRSST]

    The L2P product contains full resolution dual-view Sea Surface Temperature (SST) values. These SST use the ARC SST retrieval and cloud screening which differ from the methods used to produce the Gridded Surface Temperature (ATS_NR__2P) products. In addition to SST, the L2P products contain the ATSR Saharan Dust Index (ASDI) and the clear-sky probability estimated by the ARC cloud detection algorithm. The L2P processor also generates L3U products; these are the L2P products averaged onto a regular grid at 0.1 degree resolution (they are therefore similar to the AR / Meteo Envisat-format products). The L2P and L3U products are provided in NetCDF-4 format following GHRSST Data Specifications (GDS) v2. The L2P/L3U archive has been reprocessed with a new processor based upon the ARC SST; the changes are outlined in full in the L2P Reprocessing User Note.
