From TERRA / AQUA images toward monthly average maps of albedo fiso, fvol, fgeo:

MODIS images =>    MCD43C1 et C2 product  => Monthly means (lefèvre et al. 2013) for McClear on 2004-2011 of fiso, fgeo, fvol
   

0.05° spatial resolution (approx. 5.6 km at the equator), 3600 by 7200 images. Produced every 8 days with 16 days of acquisition, worldwide inland only

C2= snow free version from C1

  How to compute rho_white_sky and rho_black_sky from these three monthly parameters

Content: Presentation of the monthly maps of MODIS parameters (fiso, fvol and fgeo) used to generate albedo for each instant in the year, derived from holy maps of collected MODIS maps (holes due to clouds).
