with either v < 3.5 or v > 4.0 and the oceanic model are difficult to satisfy the observed reflectance 
data. 
3. CONCLUSIONS 
In this paper we have made an analysis of the airborne POLDER data over the sea by the 
multiple scattering model. Our conclusions based on this study are summarized as follows: 
1) . We found Junge type aerosol models with their ranges of the refractive index ( 1.33 ^ n ^ 
1.50, and 0 ^ k ^ 0.01 ) and Junge's index of 3.5 ^ v ^ 4.0 and the water soluble model with 
(n ~ 1.5, and k ~ 0.01 ) are the candidate model from the analysis of Medimar data. 
2) . The range of the wind field was also estimated to be 9.0 m/s ^ V ^ 14.0 m/s and 215" ^ 
W d ^ 240° , which are reasonably close to the observed wind field.
