Weekly Percent Saturated Surface Soil Moisture Anomalies This data product represents the weekly volumetric soil moisture (percent saturated soil) for the surface layer, expressed as a difference from the long term average. The average is calculated from all available years for each location and each time period, based on the length of the satellite data record. Values higher than zero represent areas that are wetter than the long term average, and areas lower than zero represent areas drier than the long term average. The data is produced from passive microwave satellite data collected by the Soil Moisture and Ocean Salinity (SMOS) satellite and converted to soil moisture using version 6.20 of the SMOS soil moisture processor. The data are produced by the European Space Agency and obtained under a Category 1 proposal for Level 2 soil moisture data. The data are gridded to a resolution of 0.25 degrees. Data quality flags have been applied to remove areas where rainfall is present during the acquisition, where snow cover is detected and when Radio Frequency Interference (RFI) is above an acceptable threshold. 2015-12-21 2018-07-10 Agriculture and Agri-Food Canada agri-geomatics-agrog@agr.gc.ca Form DescriptorsNature and EnvironmentScience and TechnologyDrainageSatellitesWaterSoilSoil qualityRemote sensingHydrology Data Product Specification (English)PDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcPsssm/en/ISO_19131_Percent_Saturated_Surface_Soil_Moisture_Data_Product_Specification.pdf Data Product Specification (French)PDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcPsssm/fr/Pourcentage_de_saturation_en_eau_de_la_surface_du_sol_ISO_19131.pdf The SMOS Soil Moisture Retrieval AlgorithmPDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcPsssm/en/Kerr2012_TGRS.pdf Pre-packaged GeoTIF filesGeoTIF http://www.agr.gc.ca/atlas/data_donnees/geo/aafcPsssm/tif/anomaly/ Pre-packaged MapsPDF http://www.agr.gc.ca/atlas/maps_cartes/aafcPsssm/anomaly/ Weekly Percent Saturated Surface Soil Moisture AnomaliesWMS https://www5.agr.gc.ca/atlas/services/imageservices/psssm_weekly_anomaly/ImageServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png Weekly Percent Saturated Surface Soil Moisture AnomaliesWMS https://www5.agr.gc.ca/atlas/services/servicesimage/psess_hebdomadaire_anomalies/ImageServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png Percent Saturated Surface Soil Moisture from SMOS Satellite DataHTML http://www.agr.gc.ca/atlas/psssm Percent Saturated Surface Soil Moisture from SMOS Satellite DataHTML http://www.agr.gc.ca/atlas/psess Weekly Percent Saturated Surface Soil Moisture AnomaliesESRI REST https://www5.agr.gc.ca/atlas/rest/services/servicesimage/psess_hebdomadaire_anomalies/ImageServer Weekly Percent Saturated Surface Soil Moisture AnomaliesESRI REST https://www5.agr.gc.ca/atlas/rest/services/imageservices/psssm_weekly_anomaly/ImageServer
