Product	Product ID	Areas	Grid (km)	Goal Accuracy	Range	Status	Remarks
All-weather sea surface wind speed	ASW	Ocean	60	±7m/s	0 - 70m/s	available (Ver.301)	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℃	-2 - 35℃	available (included in standard product Ver. 2.1 or later)	Except sea ice and precipitating areas. It is already contained in the standard SST product (Ver. 2.1 or later)
Multi-band SST	SST	Ocean	30-50	±0.8℃	-2 - 35℃	available (included in standard product Ver. 4 or later)	Except sea ice and precipitating areas. It is already contained in the standard SST product (Ver. 4 or later)
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	SMC: 0 - 100% VWC: 0 - 2kg/m²	under development	Profiles are retrieved for SMC.
Land surface temperature	LST	Land	15	Forest: ±3K Low vegetation: ±4K	0 - 50℃	available (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 development	-
High Resolution Sea Ice Concentration	HSI	Ocean at high latitudes	5	±15%	0 - 100%	available (Ver. 100)	The accuracy is evaluated as sea ice concentration (%).
Detection of thin sea ice	TSI	Okhotsk Sea Bering Sea Hudson Bay	15	80%	N/A	available (Ver. 100)	Sea ice area (≦ 30 cm) is defined as thin ice area. A flag representing whether thin ice area is dominant in a pixel is stored in a product. Accuracy is expressed in right answer rate (%).
Sea ice motion vector	SIM	Ocean at high latitudes	50	±6cm/s in latitude and longitude	0 - 40cm/s	available (Ver. 100)	-
Total Precipitable Water over Land	PWL	Land	15	±6.5kg/m²	0 - 70kg/m²	available (Ver. 100)	Vertically integrated (columnar)
Sea Ice Thickness (< 20cm)	SIT	Polar region,over ocean	15	Thin solid ice:±10cm Active frazil:±3cm	0 - 20cm	under development
Sea Ice Thickness (>= 20cm)	SIT	Polar region,over ocean	15	±20cm	0.2 - 1.2m	under development
