GCOM-W was launched by the H-IIA Launch Vehicle No. 21 (H-IIA F21) at 1:39 a.m. on May 18th, 2012 (Japan Standard Time, JST) and inserted into a planned position on the \"A-Train\" orbit. GCOM-W equipped with AMSR2 takes measurements at multiple microwave frequencies and multiple polarizations of weak electromagnetic waves in the microwave band radiated from the Earthâ\u0080\u0099s surface and the atmosphere. AMSR2 has swath of 1450 km and 7 microwave bands. The observation data will enable the creation of long-term trustworthy data sets of global physical amount. Level 2 products calculates various geophysical parameters related to water using the Level 1B or 1R products as inputs. This dataset includes Snow Depth (SND), depth of snow cover over land surface. Coverage of the product is over land only, and unit is [cm]. We do not provide snow cover over the sea ice surface. Snow depth parameter is closely related to climate variation, and this product enables us to figure out changes in distribution of global snow cover. The Pixel_Data_Quality is quality flag stored for each observation point. The provided format is HDF5. The Sampling resolution is 30 km. The current version of the product is Version 2. The Version 1 is also available. The generation unit is scene (defined as a half orbit).", "type": "Collection", "title": "GCOM-W/AMSR2 L2 Snow Depth 2021-04", "license": "other", "assets": { "metadata_ogc_17_069r3": { "roles":
