GOSAT-GW/AMSR3 L3 Snow Depth (1-Month,25km,EG)

GOSAT-GW/AMSR3 L3 Snow Depth (EG, 25 km, 1-Month) dataset is obtained from the AMSR3 sensor onboard GOSAT-GW and produced by the Japan Aerospace Exploration Agency (JAXA).GOSAT-GW was launched by the H-IIA Launch Vehicle No. 50 (H-IIA 50) at 01:33 a.m. on Jun 29th, 2025 (Japan Standard Time, JST). GOSAT-GW equipped with AMSR3 takes measurements at multiple microwave frequencies and multiple polarizations of weak electromagnetic waves in the microwave band radiated from the Earth’s surface and the atmosphere. AMSR3 has swath of 1535 km and 11 microwave bands. The observation data will enable the creation of long-term trustworthy data sets of global physical amount.Level 3 products are gridded data. They store the brightness tempreture or physical parameters data converted using grid processing and temporally statical processing.This product includes monthly mean Snow Depth (SND). SND product stores depth of snow cover over land surface.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 provided format is NetCDF4. The current version of the product is Version 01A. The physical quantity unit is [cm]. The generation unit is global. The sampling resolution is 25 km. The projection method is EG.
