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

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
