Aquarius L3 Weekly Polar-Gridded Landscape Freeze/Thaw Data V005

공공데이터포털

This Level-3 (L3) data set includes weekly Northern Hemisphere landscape freeze/thaw (FT) data derived from L-band radiometer brightness temperature observations, acquired by the Aquarius sensor on board Argentina's Satélite de Aplicaciones Científicas (SAC-D) satellite. The data are distributed on the Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0), with a spatial resolution of 36 km. The SAC-D satellite was developed collaboratively between NASA and Argentina's space agency, Comisión Nacional de Actividades Espaciales (CONAE).

MEaSUREs Polar EASE-Grid 2.0 Daily 6 km Land Freeze/Thaw Status from AMSR-E and AMSR2, Version 2

공공데이터포털

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, reports the global, daily freeze/thaw status of the landscape at 6 km resolution on EASE-Grid 2.0 Northern Hemisphere and Southern Hemisphere polar grids. The data are derived from observations acquired by the Japan Aerospace Exploration Agency's (JAXA) Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2).

VIIRS/JPSS1 Ice Surface Temperature Daily L3 Global 750m EASE-Grid 2.0 Day V002

공공데이터포털

This data set reports sea ice surface temperature (IST) derived from radiance data acquired by the Visible Infrared Imager Radiometer Suite (VIIRS). Following the approach used by MODIS, the algorithm converts VIIRS calibrated radiances into brightness temperature and computes IST using a split-window technique. VIIRS flies on board the Joint Polar Satellite System 1 (JPSS-1), also known as NOAA-20.

SMAP L3 Radiometer Global and Northern Hemisphere Daily 36 km EASE-Grid Freeze/Thaw State V004

공공데이터포털

This Level-3 (L3) product provides a daily composite of landscape freeze/thaw conditions retrieved by the Soil Moisture Active Passive (SMAP) radiometer from 6:00 a.m. descending and 6:00 p.m. ascending half-orbit passes. SMAP L-band brightness temperatures are used to derive freeze/thaw state and transition data, which are then resampled to both an Earth-fixed, Northern Hemisphere azimuthal 36 km Equal-Area Scalable Earth Grid (EASE-Grid 2.0), and to an Earth-fixed global 36 km EASE-Grid 2.0.
