    "title": "AATSR Multimission land and sea surface data, 4th Reprocessing",
    "abstract": "Advanced Along-Track Scanning Radiometer (AATSR) mission was funded jointly by the UK Department of Energy and Climate Change  External Link (DECC) and the Australian Department of Innovation, Industry, Science and Research External Link (DIISR).  This dataset collection contains data from the 4th reprocessing of the AATSR data.  This was done to make the data format consistent with that of the later Copernicus Sentinel data.\r\n\r\nThe Envisat AATSR Level 1B Brightness Temperature/Radiance product (AT_1_RBT) contains top of atmosphere (TOA) brightness temperature (BT) values for the infra-red channels and radiance values for the visible channels, on a 1-km pixel grid. Values for each channel and for the nadir and oblique views occupy separate NetCDF files within the Sentinel-SAFE format, along with associated uncertainty estimates. Additional files contain cloud flags, land and water masks, and confidence flags for each image pixel, as well as instrument and ancillary meteorological information.\r\n\r\nThis AATSR product [ENV_AT_1_RBT] in NetCDF format stemming from the 4th AATSR reprocessing, is a continuation of ERS ATSR data and a precursor of Sentinel-3 SLSTR data.  It has replaced the former L1B product [ATS_TOA_1P] in Envisat format from the 3rd reprocessing.  Users with Envisat-format products are recommended to move to the new Sentinel-SAFE like/NetCDF format products.  The 4th reprocessing of Envisat AATSR data was completed in 2022.\r\n\r\nThe instrument uses thermal channels at 3.7, 10.8, and 12 microns wavelength; and reflected visible/near infra-red channels at 0.555, 0.659, 0.865, and 1.61 microns wavelength.  Data is available from 2002 to 2012.\r\n\r\nThe data were acquired by the European Space Agency's (ESA) Envisat satellite, and the Centre for Environmental Data Analysis (CEDA) mirrors the data and allows for access via JASMIN.",
