The recommended AATSR Level 3 products for Land Surface Temperature (LST) applications are the Level 3 products that have been produced by the University of Leicester (UOL).
These Level 3 products have been generated from Level 2 UOL LST products which use the same LST retrieval method as the Gridded Surface Temperature (ATS_NR__2P) products. However, significantly improved auxiliary data sets for land cover, green vegetation fraction and total column water vapour are also applied (see "Available Resources" section below for details). In addition to LST, the UOL LST products contain the aforementioned auxiliary information, LST uncertainty estimates, NDVI and quality control flags.
The Level 3 products are provided in NetCDF-4 format, and have been generated from the 3rd reprocessed AATSR dataset by the LST project team at the University of Leicester funded by ESA and NCEO.Further documentation is available via the NEODC website.
