Except sea ice areas. The goal accuracy is defined for the wind speed more than 17 m/s.
It was released to the public on Oct. 6, 2015.
10-GHz (high-resolution) SST SST Ocean 30 ±0.8℃ 9 - 35℃ available
(included in standard product Ver. 2.1 and Ver. 3.0)
Except sea ice and precipitating areas.
It is already contained in the standard SST product (Ver. 2.1 and Ver. 3.0)
Soil moisture (SMC) and vegetation water content (VWC) based on the land data assimilation methodology LDA land over the continents of Africa and Australia 25 SMC: ±8%
VWC: ±1kg/m²
0 - 100%
0 - 2kg/m²
Profiles are retrieved for SMC.
Land surface temperature LST Land 15 Forest: ±3K

(Ver. 100)
Temperature at a canopy top is defined as land surface temperature.
Vegetation water content VWC Land 10 ±1kg/m² 0 - 4kg/m² under
Advanced (high-resolution) sea ice concentration ASI Ocean at high latitudes 5 ±15% 0 - 100% under
Accuracy is expressed in absolute value of sea ice concentration (%).
