Global Attributes:	title: ESA CCI snow SWE product level L3C daily institution: FMI source: SSMI brightness temperature data from 19 & 37GHz channels. WMO synoptic in-situ snow depth measurements, daily averages history: 20200403T171406Z: ESA snow_cci SWE processing line, version 1.0 references: http://snow-cci.enveo.at/ tracking_id: 79e70190-0424-4d30-9bc9-edbda1ff1942 Conventions: CF-1.7 product_version: prototype format_version: CCI Data Standards v2.1, 2019 summary: The ESA CCI Snow SWE product provides daily information on mass of the snow cover. Snow water equivalent (swe) is measure of the ammount of water contained within a snow pack and is provided in mm, similar to precipitation information. The product is based on low resolution passive microwave satellite data combined with in-situ snow depth measurements and is provided resampled to 0.25 degree latitude longitude grid. Information is provided on all land areas on Northern hemisphere excluding mountainous regions, glaciers and Greenland that have been masked from the product. The SWE estimates are complemented with statistically derived accuracy estimate accompanying each SWE estimate (on a pixel level). keywords: SSMI, snow water equivalent, DMSP id: 19910326-ESACCI-L3C_SNOW-SWE-SSMI-DMSP-fv1.0.nc naming_authority: fi.fmi keywords_vocabulary: NASA Global Change Master Directory (GCMD) Science Keywords cdm_data_type: grid comment: The following auxiliary datasets are used for product generation: ESA CCI Land Cover from 2000: water bodies aggregated to the pixel spacing of the SWE product and, providing percentage (0-100)% of water within pixel, with 50% threshold used for this version of the product.
