It forms part of the first version of their Climate Research Data Package (CRDP v1). It is derived from a thermal model driven and constrained by satellite data. Grid products of CDRP v1 are released in annual files, covering the start to the end of the Julian year. This corresponds to average annual ground temperatures and is provided for specific depths (surface, 1m, 2m, 5m , 10m).\r\n\r\nCase A: It covers the Northern Hemisphere (north of 30°) for the period 2003-2017 based on MODIS Land Surface temperature merged with downscaled ERA5 reanalysis near-surface air temperature data.\r\nCase B: It covers the Northern Hemisphere (north of 30°) for the period 1997-2002 based on downscaled ERA5 reanalysis near-surface air temperature data which are bias-corrected with the Case A product for the overlap period 2003-2018 using a pixel-specific statistics for each day of the year.","keywords":"Permafrost, CCI, Ground Temperature","publicationState":"citable","dataPublishedTime":"2020-11-02T15:42:25","doiPublishedTime":"2020-11-02T16:04:55","updateFrequency":"notPlanned","status":"superseded","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/31973/?format=json","dataPath":"/neodc/esacci/permafrost/data/ground_temperature/L4/area4/pp/v02.0","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":33756960822,"numberOfFiles":23,"fileFormat":"Data are in NetCDF format"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/8767/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/2567/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/27732/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50547/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50548/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/62645/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/70622/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92060/?format=json"],"dataLineage":"Data have been produced by the ESA CCI Permafrost project as part of ESA's Climate Change Initiative programme","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/10789/?format=json"],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/29966/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/31981/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/141415/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141414/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141416/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141417/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141418/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141419/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141438/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141439/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141420/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141421/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141422/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141423/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141424/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141425/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141426/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141427/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141428/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141429/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141430/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141431/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141432/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141433/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141434/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141435/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141436/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/141437/?format=json"],"procedureAcquisition":null,"procedureCompositeProcess":null,"procedureComputation":"https://catalogue.ceda.ac.uk/api/v2/computations/31971/?format=json","permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2596/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"https://artefacts.ceda.ac.uk/licences/specific_licences/esacci_permafrost_terms_and_conditions.pdf","licenceClassifications":"any"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
