This study investigates spatial patterns in glacier characteristics and area changes at decadal scales in the eastern Himalaya - Nepal (Arun and Tamor basins), India (Teesta basin in Sikkim) and parts of China and Bhutan - based on various satellite imagery: Corona KH4 imagery, Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and Advanced Spaceborne Thermal Emission Radiometer (ASTER), QuickBird (QB) and WorldView-2 (WV2). We compare and contrast glacier surface area changes over the period of 1962-2000/2006 and their dependency on glacier topography (elevation, slope, aspect, percent debris cover) and climate (solar radiation, precipitation) on the eastern side of the topographic barrier (Sikkim) versus the western side (Nepal). <br /> Glacier mapping from 2000 Landsat ASTER yielded 1463 +/- 88 km(2) total glacierized area, of which 569 +/- 34 km(2) was located in Sikkim and 488 +/- 29 km(2) in eastern Nepal. Supraglacial debris covered 11% of the total glacierized area, and supraglacial lakes covered about 5.8% of the debris-covered glacier area alone. Glacier area loss (1962 to 2000) was 0.50 +/- 0.2% yr(-1), with little difference between Nepal (0.53 +/- 0.2% yr(-1)) and Sikkim (

When the program ran, from its start year to the latest document year. A hatched bar means the start is our estimate.
Axis: award years, end from years in documents. The start year comes from award fiscal year; the end is the latest document year, so the program may have run longer.

DEC topic and subject tags. They describe the documents, not what the program was. Each tag opens its evidence in the drawer.
Programs worth reading next, by topic, implementer, country and years. Similar by facets (topic, implementer, country, years) and, when available, description. It says the programs look alike, not how they are related in time. Source: catalog facets
