  1. MODIS Observed Surface and Atmosphere Characters over Tibetan Plateau Menglin Jin, PhD

  2. Glaciers as a Harbinger of Global Change • Glacier National Park • 110 glaciers have disappeared in the past 150 years • 37 remaining glaciers expected to disappear within 25 years • Mt. Kilimanjaro • All glaciers likely to disappear within 20 years • 160,000 glaciers worldwide being monitored by satellites (especially Landsat 7/ETM+ and Terra/ASTER) Gangotri Glacier, Himalaya Bhutan-Himalaya

  24. Auqa-Terra Cloud Fraction, January 2005

  25. Diurnal, seasonal, and inter-annual variations of rainfall, clouds, and water vapor over the Tibetan Plateau are examined using the most advanced satellite observations. Such understanding is critical for further modeling this regions. • Land Information System for easier accessing and analyzing MODIS land observations is desired Summary
