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
