Cryosphere Field Work in the Langtang Valley, Nepal


A team from the Cryosphere Initiative at the International Centre for Integrated Mountain Development (ICIMOD) will head to the Langtang valley and the Yala glacier for a spring field expedition. The expedition is part of a long-term field data collection project carried out in collaboration with Utrecht University, the Department of Hydrology and Meteorology Nepal at Kathmandu University, and the Norwegian Water Resources and Energy Directorate. 

Activity details:

1. Glacier mass balance, Yala glacier:

  • Maintain stake network on the Yala glacier to measure biannual glacier mass balance. 
  • Measure snow accumulation, including snow-pit observations with density measurements.
  • Download ground temperature data.

2. Hydro-met fieldwork, Langtang valley:

  • Maintain automatic weather stations (AWS), tipping buckets, and temperature loggers.
  • Maintain and improve seasonal snow observations.
  • Maintain and reinstall hydrological stations and measure discharge. 
  • Measure biannual surface lowering of debris-covered glaciers with an unmanned aerial vehicle (UAV).
  • Obtain samples for black carbon and dust in seasonal snow.
