In this week’s Video of the Week, an automatic weather station (AWS) is installed on Yala Glacier in Nepal, one of the world’s most studied glaciers. In the video shared by the International Centre for Integrated Mountain Development (ICIMOD) on October 16, a young researcher, Anushilan Acharya, is identified with the hashtag #girlsonice.
The installation is part of a push by ICIMOD to increase data collection on glaciers in the Hindu Kush Himalaya. Of the 54,252 identified glaciers in the HKH, only seven are monitored by ICIMOD researchers. The information is essential to understanding how climate change might affect the region’s water resources.
The weather stations provide data points for glacier monitoring. Last year, GlacierHub reported on a study which found approximately 21 percent of Yala’s annual snowfall was returned to the atmosphere via sublimation, a rate higher than most glaciers on Earth’s tallest mountain ranges.
Fieldwork on Yala is notoriously difficult. The glacier is a four-day hike from the start of the Langtang Valley, which is a day’s drive from Kathmandu. In the sublimation study, an eddy covariance system was installed to measure the rate of snow loss to the atmosphere. The instruments required so much energy to power that the team had to lug a car battery up the glacier to ensure it would have sufficient energy to run during the research.
