From: A new simple concept for ocean colour remote sensing using parallel polarisation radiance
The reflectance of the upward total radiance and PPR at 670 nm measured by POLDER at the 12th observing angles on 10 July 2003.
The reflectance is defined as R = πL/F0 cos(θ0), where L, F0 and θ0 are the total radiance (or PPR), extra-terrestrial solar irradiance and solar zenith angle, respectively. (a) Reflectance of total radiance, (b) reflectance of PPR, (c) reflectance of total radiance with solar zenith angle larger than 35°. The maps were generated by the Microsoft Visual C++ 6.0 and Adobe Photoshop CS softwares.
