#### Description

This product is the temperature of sea surface.

For data after 2021-11-28, see [the V3 dataset](https://developers.google.com/earth-engine/datasets/catalog/JAXA/GCOM-C/L3/LAND/SST/V3).

GCOM-C conducts long-term and continuous global observation and data collection to elucidate the
mechanism behind fluctuations in radiation budget and carbon cycle needed to make accurate
projections regarding future temperature rise. At the same time, cooperating with research
institutions having a climate numerical model, it contributes to reduction of errors in
temperature rise prediction derived from the climate numerical model and improvement of accuracy
of prediction of various environmental changes. SGLI mounted on GCOM-C is the succession sensor
of the Global Imager (GLI) mounted on ADEOS-II (MIDORI II) and is the Imaging Radiometer which
measures the radiation from near-ultraviolet to thermal infrared region (380 nm-12 um) in 19
channels. Global observation of once for approximately every two days is possible at
mid-latitude near Japan by observation width at ground greater than 1,000 km. In addition, SGLI
realizes high resolution than the similar global sensor and has a polarized observation function
and a multi-angle observation function.
