Cryosphere
Langtang Valley
23 April 2016 to 13 May 2016
Background
Researchers from the Cryosphere Initiative of the International Centre for Integrated Mountain Development (ICIMOD) leave for Langtang Valley and Yala Glacier this spring for routine maintenance of meteorological stations, data collection, and mass balance measurements in selected research areas. Langtang Valley is a core research area for ICIMOD. Since 2012, the centre monitors the operation of meteorological and hydrological stations. Repeat monitoring of two debris-covered glaciers in the valley with unmanned aerial vehicles (UAV) has provided a unique data for examining the evolution of debris-covered glaciers and the role of ice cliffs and ponds in total glacier melt.
Yala Glacier’s length and mass balance have been monitored since 2011 resulting in important climate indicators on the impact of climate change for water resource management. The research is carried out in collaboration with Kathmandu University (KU), Tribhuvan University (TU) and the Department of Hydrology and Meteorology, Government of Nepal (DHM, GoN) in the framework of the Nepal Cryosphere Monitoring Programme. Snow samples will be collected and used to measure atmospheric pollutants like black carbon (BC). Ground surface temperatures are recorded to learn more about high altitude permafrost.
Details of activities during the expedition are provided below:
25th of April to 06 of May Place: Melamchi, Gangja La Pass Group lead:
Maxime Litt, Glaciologist.
Snow Accumulation and Melt Processes in Himalayan Catchment (Snow-AMP)’ project installed four snow monitoring automatic weather stations in Langtang Valley September 2015. The stations provide accurate measurements of snow height and snow water equivalent. Snow-AMP is a collaboration between ICIMOD, the Norwegian Water Resources and Energy Directorate (NVE), Norway, the Department of Hydrology and Meteorology (DHM), Government of Nepal, Kathmandu University (KU) and Tribhuvan University (TU), Nepal.
Researchers will visit four snow stations conducting instrument maintenance, download pictures from time lapse cameras, and measure snow density and depth manually (for comparison with instruments).
Date: 27 April, 2016 to 10 May, 2016 Places to cover: Lirung Glaciers, Kyanging and Langtang Group Lead:
