description: GOSAT-GW/AMSR3 L2 Total Precipitable Water 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 2 products store various geophysical parameters related to water using the Level 1 products as inputs.This product includes Total Precipitable Water (TPW). TPW product represents amount of vertically accumulated water vapor (H2O in gaseous state) in the atmosphere, and defined as amount of water per unit area. Total precipitable water is one of essential hydrological parameters describing state of the atmosphere along with precipitation and cloud liquid water.The provided format is NetCDF4. The current version of the product is Version 01A. The physical quantity unit is [kg/m2]. The generation unit is scene (defined as a half orbit). The sampling resolution is 15 km.
