China Ocean Colour and Temperature Scanner

Missions → HY-1D (Operational) , HY-1C (Operational)

Ocean-colour and temperature scanner flown on HY-1D.

Sensor

The China Ocean Colour and Temperature Scanner (COCTS) is a spaceborne passive optical radiometer covering 10 spectral bands from 402 nm to 12,500 nm, providing simultaneous ocean-colour and sea-surface temperature measurements.[1] Ground sampling distance is approximately 1,100 m.[1] COCTS has flown on HY-1A, HY-1B, HY-1C, and HY-1D.[1]

Swath coverage has increased across mission generations. On HY-1A the swath was 1,400 km.[2] HY-1B achieved approximately 2,800 km through an extended scan geometry.[3] On HY-1C and HY-1D the swath reached approximately 2,900 km.[1]

The band configuration has a minor difference between HY-1C and HY-1D. Band 7 spans 730-770 nm (40 nm bandwidth) on HY-1C, and 734-754 nm (20 nm bandwidth) on HY-1D;[4][5] all other bands are nominally identical across the two satellites. The instrument is demonstrated for ocean-colour water-leaving radiance retrieval and sea-surface temperature retrieval.[1]
