해양관측위성 2호 공간해상도에 대한 초기 광학 설계

Abstract

The GOCI is one of the three payloads of the COMS satellite. It acquires data in 8 visible spectral bands with a spatial resolution of about 500 m over the Korean sea. The ocean data prooducts that can be derived from the measurements are mainly the chlorophyll concentration, the optical diffuse attenuation coefficients, the concentration of dissolved organic material or yellow substance, and the concentration of suspended particles in the near-surface zone of the sea. In operational oceanography, satellite derived data products are used in conjunction with numerical models and in situ measurements to provide forecasting and now casting of the ocean state. For the next generation GOCI, the baseline instrument concept is a compact TMA telescope or Korchy type, and in this research, for focusing on the GSD as a spartial resolution, we approached two design concept with 250m and 100m GSD.re mainly the chlorophyll concentration, the optical diffuse attenuation coefficients, the concentration of dissolved organic material or yellow substance, and the concentration of suspended particles in the near-surface zone of the sea.
