description: GOSAT-GW/AMSR3 L3 Soil Moisture Content (EG, 25 km, 1-Day) 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 Earthâs 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 averaged Soil Moisture Content (SMC). SMC product represents the wetness of the soil near the ground surface. Soil moisture near the coastline, around large lakes and marshes, and in areas with large areas of dense forest cannot be estimated. Because microwave radiometers can acquire data at a high frequency and on a regular basis, this product is being used for monitoring large cultivated areas on continents.The provided format is NetCDF4. The current version of the product is Version 01A. The physical quantity unit is [%]. The generation unit is global. The sampling resolution is 25 km. The projection method is EG.
