This dataset contains the output of a gapfilling algorithm applied to MODIS snow products for the Pyrenees mountains as presented by Gascoin et al. (2015) and updated to the period 2000-Sep-01 to 2015-08-31 (15 hydrological years) Pirineos_gapfilled.tif: a multiband geotiff raster file in WGS84 UTM30N (EPSG:32630) at 500 m resolution with values 200 (snow) or 25 (no snow); Corner Coordinates: Upper Left ( 607750.000, 4789250.000) ( 1d40'21.72"W, 43d14'54.08"N) Lower Left ( 607750.000, 4665250.000) ( 1d41'46.55"W, 42d 7'55.05"N) Upper Right ( 973750.000, 4789250.000) ( 2d49'18.48"E, 43d 6'27.65"N) Lower Right ( 973750.000, 4665250.000) ( 2d43' 8.76"E, 41d59'47.87"N) Center ( 790750.000, 4727250.000) ( 0d32'47.24"E, 42d38'34.10"N) Pirineos_gapfilled_dates.csv: a csv file indicating the date corresponding to each band (year, month, day) dem_Pirineos_UTM30_px500.tif: a geotiff raster of the elevation in WGS84 UTM30N (input of the gap-filling algorithm) with the same extent and resolution as 1. aspect_Pirineos_UTM30_px500.tif: a geotiff raster of the slope aspect in WGS84 UTM30N (input of the gap-filling algorithm) with the same extent and resolution as 1.
