pixel radiance simulation differing by one order in case of ocean BRDF

[Srinivas Kolluru]

Hello,

I am trying to perform 6sv simulation to generate top-of-atmosphere pixel radiance with following parameters,

Ground.Reflectance.HomogenousOcean(3.73,0,35,3.78)

aot550=0.12

AeroProfile.PredefinedType(AeroProfile.Maritime)

AtmosProfile.PredefinedType(AtmosProfile.MidlatitudeWinter)

s.geometry.solar_z=33.42 #actual value 33.42
s.geometry.solar_a=71.95 #actual value 71.95
s.geometry.view_z=22.14 #actual value 22.144
s.geometry.view_a=34.2 #actual value 34.2
s.geometry.day=15
s.geometry.month=12

The pixel radiances i obtain with py6s are of the order 1-4 w/m2/sr/mic.

However, for similar conditions, i found that the L_Top-of-Atmosphere is between 10-60 mW/m2/nm/sr. I am not sure why there is one order of difference between the 6sv simulated pixel radiance and actual L_TOA.

Please help.
