Note that the RADIANCE reported in the above LUT IS NOT DIVIDED BY PI. To convert it to the NORMALIZED RADIANCE, one needs to divide it by PI. 

n_wv = number of wavelengths: 3 (354, 388, 388) 
n_hgt = number of aerosol layer heights: 5 (for sulphate-urban/industrial model its peak aerosol height is at surface-0 km with an exponential distribution)
n_model = number of models: 7
