Only quality-screened Level 2 data were included, applying optimized filtering criteria to ensure data reliability. Monthly Level 3 products were produced by spatial binning onto a regular latitude–longitude grid using an area-weighted averaging approach. The weighting and count vectors are used to consistently apply this weighted averaging during the Level 3 gridding, enabling the calculation of mean values and associated uncertainties.\r\n\r\nDetailed information on the Level 3 algorithm can be found in the Algorithm Theoretical Basis Document (ATBD).\r\n\r\nThe version number is 1.0. The data are provided in NetCDF format.","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}],"acquisitionComponent":[{"ob_id":45756,"independentInstrument":[],"instrumentplatformpair_set":[{"ob_id":14667,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/846/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/8029/?format=json","relatedTo":{"ob_id":45756,"uuid":"7ce156c23f104701a9cf9f08c5bc6ea2","short_code":"acq"}}]}],"identifier_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/218653/?format=json"]}
