AMSR2 was launched on 18 May 2012, onboard the Global Change Observation Mission - Water (GCOM-W) satellite developed by the Japan Aerospace Exploration Agency (JAXA). The GCOM-W mission aims to establish the global and long-term observation system to collect data, which is needed to understand mechanisms of climate and water cycle variations, and demonstrate its utilization. AMSR2 onboard the first generation of the GCOM-W satellite will continue Aqua/AMSR-E observations of water vapor, cloud liquid water, precipitation, SST, sea surface wind speed, sea ice concentration, snow depth, and soil moisture. AMSR2 is a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. The antenna of AMSR2 rotates once per 1.5 seconds and obtains data over a 1450 km swath. This conical scan mechanism enables AMSR2 to acquire a set of daytime and nighttime data with more than 99% coverage of the Earth every 2 days. The “Final” SSTs are processed when RSS receives the atmospheric model National Center for Environmental Prediction (NCEP) Final Analysis (FNL) Operational Global Analysis. The NCEP wind directions are particularly useful for retrieving more accurate SSTs and wind speeds. onGoing NASA/JPL/PODAAC > Physical Oceanography Distributed Active Archive Center, Jet Propulsion Laboratory, NASA distributor https://sextant.ifremer.fr/geonetwork/srv/api/records/eed8c4c5-9d71-4406-b398-bae66fde62fb/attachments/AMSR2-REMSS-L2P-v8.2.jpg Oceanographic geographical features GEMET - INSPIRE themes, version 1.0 2018-01-01 publication 2018-07-27T14:39:48 publication geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme Ocean Temperature Cersat - Parameter 2024-07-26 publication 2024-07-26 publication geonetwork.thesaurus.local.theme.cersat_parameter GHRSST Cersat - Project 2025-07-31 publication 2025-07-31 publication geonetwork.thesaurus.local.theme.cersat_project Less than 24 hours Cersat - Latency 2024-07-26 publication 2024-07-26 publication geonetwork.thesaurus.local.theme.cersat_latency /Ocean Temperature/Sea Surface Temperature Cersat - GCMD parameter 2024-01-04 publication 2024-01-04 publication geonetwork.thesaurus.external.theme.GCMDparameter Centre de données ODATIS 2024-10-16 publication 2024-10-16 publication geonetwork.thesaurus.local.theme.odatis_centre_donnees Variables ODATIS 2023-10-13 publication 2023-10-13 publication geonetwork.thesaurus.local.theme.odatis_variables /Observational data/satellite Type de jeux de donnée ODATIS 2024-10-15 publication 2024-10-15 publication geonetwork.thesaurus.local.theme.type_jeux_donnee Sea temperature ODATIS aggregation parameters and Essential Variable names 2025-07-29 publication 2025-07-29 publication geonetwork.thesaurus.external.theme.NVS.OD1 None grid 25 oceans -180.00 180.00 -90.00 90.00 2012-07-02 L2P https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/ghrsst/open/docs/GDS20r5.pdf WWW:LINK User guide /home/datawork-cersat-public/provider/ghrsst/satellite/l2p/gcom_w1/amsr2/remss-l2p-amsr2/8.2/data/dm/ NETWORK:LINK Local path on Datarmor Local path https://cmr.earthdata.nasa.gov/virtual-directory/collections/C2596983413-POCLOUD/ WWW:LINK HTTPS PODAAC https://doi.org/10.5067/GHAM2-2PR82 DOI Digital Object Identifier (DOI)
