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

  2. I. Process chain • Target period for the statistics: DOY (209-249) (i.e. August -early Sep) • Target region: P41R28 (same with the investigation using our temporal Landsat albedo) • Visually selected the most-clear day in late August for each year during 2000-2012 • MCD43A3.2000249.Albedo.bin MCD43A2.2000249.bin 2000 • MCD43A3.2001241.Albedo.bin MCD43A2.2001241.bin 2001 • MCD43A3.2002241.Albedo.bin MCD43A2.2002241.bin 2002 • MCD43A3.2003233.Albedo.bin MCD43A2.2003233.bin 2003 • MCD43A3.2004241.Albedo.bin MCD43A2.2004241.bin 2004 • MCD43A3.2005233.Albedo.bin MCD43A2.2005233.bin 2005 • MCD43A3.2006241.Albedo.bin MCD43A2.2006241.bin 2006 • MCD43A3.2007241.Albedo.bin MCD43A2.2007241.bin 2007 • MCD43A3.2008241.Albedo.bin MCD43A2.2008241.bin 2008 • MCD43A3.2009241.Albedo.bin MCD43A2.2009241.bin 2009 • MCD43A3.2010233.Albedo.bin MCD43A2.2010233.bin 2010 • MCD43A3.2011233.Albedo.bin MCD43A2.2011233.bin 2011 • MCD43A3.2012225.Albedo.bin MCD43A2.2012225.bin 2012 • 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 • 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 • Consistent trend, but a little bit lower than the generation from Landsat albedo

  3. I. Temporal plots of Landsat-scale-like MCD43A Black Sky Albedo (BSA) using Mask1

  4. I. Temporal plots of Landsat-scale-like MCD43A Black Sky Albedo (BSA) using Mask1 (Cont.)

  5. Big jump of highFire BSA at age-28 in the temporal plots BSA difference (day2012225-2011233) Scale factor 0.001 MCD43A-BSA(day 2011-233) MCD43A3-BSA (day 2012-225)

  6. II. Temporal plots of Landsat-scale-like MCD43A Black Sky Albedo (WSA) using Mask2

  7. II. Temporal plots of Landsat-scale-like MCD43A White Sky Albedo (WSA) using Mask2 (cont.) Note: To avoid illumination direction effect in BSA, WSA is better for the cross comparison of trends between the generation from MODIS and Landsat

  8. II. Temporal plots of Landsat-scale-like MCD43A BSA & WSA combination (WSA) using Mask2 (cont.)

  9. II. Temporal plots of Landsat-scale-like MCD43A Black Sky Albedo (BSA) using Mask2

  10. III. Temporal plots of Landsat-scale-like MCD43A WSA &BSA using Mask2
