MODIS albedo data from the MOD10A1 snowcover product have been aggregated to the 25 km resolution grid of the Modèle Atmosphérique Régionale (MAR) regional climate model for comparison and data assimilation purposes. MOD10A1 data have been reprojected to the MAR v3.2 grid, and have been assigned to the closest MAR grid box based on distance from the center of each grid box. The yearly files are labeled in the following format: MOD10A1.Ayyyy.005.MAR.best.mat and MOD10A1.Ayyyy.005.MAR.allq.mat Within each yearly file, data are provided for the period beginning April 1 and ending September 31. The files ending with ".best.mat" were produced only with data flagged as "good quality" within the MODIS product, while all albedo data provided the MCD43A3 product were used to produce the files ending with "allq.mat". The files contain the following variables average (average MODIS value within each grid box) median (median MODIS value within each grid box) n (number of good MODIS values within each grid box) number (number of MODIS grid boxes assigned to the MAR grid box) stdev (standard deviation of MODIS data assigned to each grid box) The variables each have the dimensions (110 x 60 x ddd), where 110 is the MAR y-coordinate, 60 is the MAR x-coordinate, and ddd is the Julian day for a particular year.
