Landscape scale surface albedo in Idaho/Montana from 2000-2012 MCD43A products

1. Target period for the statistics: DOY (209-249) (i.e. August -early Sep) 2. Target region: P41R28 (same with the investigation using our temporal Landsat albedo)3. Visually selected the most-clear day in late August for each year during 2000-2012

4. Mosaic (since p41r28 cover two corners of h10v04 and h09v04), Reprojection (SIN to UTM) and Resample (469.56m to 30m using NN) Via MODIS Tools-MRT plus script

5. Make the mask of clear region over the 13-year Landsat-scale-like MCD43A3 and MCD43A2 data track• Mask1: Only In terms of MCD43A2 (QA=0 or 1) and MCD43A3 ( BSA &WSA !=32767 FillValue) • Mask2: Further apply the 23-clear-day mask that used in Landsat’s landscape albedo statistics

6. Consistent trend, but a little bit lower than the generation from Landsat albedo

Note: To avoid illumination direction effect in BSA, WSA is better for the cross comparison of trends between the generation from MODIS and Landsat
