        dct:description         "GOSAT-GW/AMSR3 L2 Sea Ice Concentration 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 2 products store various geophysical parameters related to water using the Level 1 products as inputs.This product includes Sea Ice Concentration (SIC). SIC product stores percentage of sea ice coverage within target ocean area. There is no sea ice within pixel area when sea ice concentration is 0%, and all pixel area is covered by sea ice when it shows 100%. We can learn distribution of sea ice immediately using this product, and it become more and more important because of recent decrease of Arctic sea ice cover.The provided format is NetCDF4. The current version of the product is Version 01A. The physical quantity unit is [%]. The generation unit is scene (defined as a half orbit). The sampling resolution is 15 km." ;
