Abstract
This paper focuses on detection of the cloud coverage and its thermodynamic phase using the combined data derived from POLDER and OCTS on board the satellite ADEOS. The POLDER has provided polarization information with multi-angle viewing. This directional information is closely related to the scattering behavior of cloud particles in light scattering simulations. Thermal data given by OCTS infrared channels is available to determine the cloud top temperature. Our basic idea to detect the cloud thermodynamic phase is based on the combination of polarization from POLDER and brightness temperature from OCTS. It is shown that our algorithm has improved the distinction of water/ice cloud.
