The geostationary ocean color imager (GOCI), as the world’s first operational sensor, is aiming at monitoring short-term and small-scale changes of waters over northwestern Pacific Ocean. Before assessing its capability detecting subdiurnal seawater properties, a fundamental understanding uncertainties normalized water-leaving radiance (nLw) products introduced by atmospheric correction algorit...

We developed a principal-component based inversion approach – CIMAP, to retrieve aerosol properties from AERONET measurements of optical depths (AODs) and sky radiances. Capitalizing on the correlation in properties, CIMAP reduces retrieval parameter space saves time by more than 80% adopting 7-8 principal components process, compared retrievals regular space. As algorithm test, is implemented ...

Radiative transfer in the Earth’s atmosphere under clear-sky conditions strongly depends on turbidity due to aerosols and hydrometeors. It is therefore important know its temporal radiative properties for a given site when objective optimize solar energy that collected there. Turbidity can be studied via measurements models of global radiation reaching ground cloudless conditions. These general...
