Abstract

The paper compares the results of two alternative methods for studying glacier variations in Mt. Naimona'Nyi in the western Himalayas on Tibet. This paper describes a grid method for studying multi-temporal glacier variations from space. By combining glacier spatial data from various satellite images or maps at sequential times, the grid method allows us to detect both dynamic variation and random noise in glacier distribution among the sequential data sets due to different data sources. Our results show that random noise, equal to 5.5% of the total glacier area in the Mt. Naimona'Nyi region, as taken from individual classification results by bands algorithms, was much larger than that of the measurement uncertainty calculated by sensor resolution and co-registration error. Glaciers in the region both retreated and advanced during the last several decades. Retreat dominates, however, and accelerates. Most of the glacier retreat area occurs at the termini of glaciers in the southeastern slopes of the two regions, whereas most of the glacier advance area occurs at the termini of glaciers in the northwestern slopes. The glacier recessions in the Mt. Naimona'Nyi of the Himalayan regions are dramatic compared with Mt. Geladandong region in the central Tibetan Plateau.
