Example of elaborate aerosols parameters  

In the following we present several examples of aerosol retrievals mainly optical thickness and angström exponent. All these retrievals are performed by an algorithm developed by F. Waquet (PhD student). In fig. 9 (click for a full size picture) are presented microPOL retrievals on a short transect (~30 km) over the North Sea close to Dunkerque City.

Figure 10 : Retrieved optical thickness over Mediterranean Sea (October 11th 2001) during the FRENCH experiment. Simultaneous lidar profil is also presented as well as comparison with Modis-Terra retrievals and sunphotometer
