3MI Cloud

This project, led by Atmospheric Optics Laboratory, provides support to the development of cloud property retrieval algorithms from the 3MI instrument on EUMETSAT Polar System – Second Generation (EPS-SG), in particular those which take advantage of the unique characteristics of 3MI as compared to METimage, namely the multi-angular viewing and the measurement of polarisation.

HYGEOS is responsible for the validation: it includes defining the method, performing the analysis and reporting the results. This task implies the generation of new synthetical data for 3MI using the simulator developped for the 4MSDS project. The new synthetic data will have to be even more realistic to comply with the testing of surface reflectance algorithm. HYGEOS takes also part in the Look-Up Table optimization and computation.

3MI synthetic data. Left panel is 865 nm total intensity. The Right panel is 865nm polarized intensity. G, CB and BS stand for Glitter, Cloud Bow and Back-Scattering, respectively. Contour lines show the scattering angle.
