COCTS
 

   COCTS (Chinese Ocean Color and Temperature Scanner) is a medium-resolution optical imager developed by SITP (Shanghai Institute of Technical Physics) of CAS (China Academy of Sciences), China. The objective of the radiometer is global ocean color monitoring for the study of biological oceanography, including chlorophyll concentration, suspended sediment concentration, dissolved organic matter, pollutants, as well as sea surface temperature. COCTS consists of the following subsystems: optics, scanner, FPA (Focal Plane Array) and an electronics box. Imagery is provided in 8 VNIR (Visible Near Infrared) and in two TIR (Thermal Infrared) bands with a spatial resolution of 1.1 km. The swath width is ~1600 km. The instrument data rate is 0.67 Mbit/s.

The design characteristics of COCTS are similar to those of SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) flown on the OrbView-2 mission of ORBIMAGE (launch Aug. 1, 1997), and to those of OCTS (Ocean Color and Temperature Scanner) flown on ADEOS (launch Aug. 17, 1996).
