This sensor measures precipitation volumes with the tipping technique, where each signal is a fixed volume of water. It is located in the main Langtang Valley floor, located at an old Yak pasture. It is not operational anymore.

Digital polygon data of Glaciers of Bhutan in 1990. This dataset is created using Landsat MSS, imageries of 1990. The glacier outlines was derived semi-automatically using object-based image classification (OBIC ) method separately for clean ice and debris cover and further editing and validation was done carefully by draping over the high resolution images from Google Earth.

Digital polygon data of Glaciers of Bhutan in 2010. This dataset is created using Landsat TM and ETM+, imageries of 2010. The glacier outlines was derived semi-automatically using object-based image classification (OBIC ) method separately for clean ice and debris cover and further editing and validation was done carefully by draping over the high resolution images from Google Earth.

This dataset provides discharge measurements at the outlet or the terminus lake at Lirung Glacier in Langtang Valley. The station is no longer operational. Discharge calculated from stage height measurements over multiple years, based on a rating curve developed locally with rhodamine dilution. At the location of the station is now the inlet for the hydropower plant.

Landslide data of Koshi basin is digitized from topo sheets published in 1990s.

Digital polygon data of Glaciers of Nepal in 1980. This dataset is created using Landsat MSS, imageries of 1980. The glacier outlines was derived semi-automatically using object-based image classification (OBIC ) method separately for clean ice and debris cover and further editing and validation was done carefully by draping over the high resolution images from Google Earth.

This sensor measures precipitation volumes with the tipping technique, where each signal is a fixed volume of water. It is located next to a large Pluviometer on the left moraine (looking up-valley) or Langshisha Glacier in the Langtang Valley. It is no longer operational.

This sensor measures precipitation volumes with the tipping technique, where each signal is a fixed volume of water. It was located at the hydropower plant in Syafru Besi but is no longer operational.

Digital polygon data of Glaciers of Nepal in 1980, 1990, 2000 and 2010. This dataset is created using Landsat MSS,TM and ETM+ imageries of four respective decades. The glacier outlines were derived semi-automatically using object-based image classification (OBIC ) method separately for clean ice and debris cover and further editing and validation was done carefully by draping over the high resolution images from Google Earth. Moreover, the glacier outlines for 2000, 1990 and 1980 were derived manually modifying the glacier outlines of 2010 by overlaying separately the images of respective decades.
