🌡️ Early results show isotopes can trace sublimation during snowfall-free periods, a key step in improving climate and water predictions.

Recent milestones in the Chalong River catchment and Panikhar include:
📈 Installation of stream gauge and turbidity sensors in the Chalong River / Panikhar
🌡️ Deployment of an automatic weather station (AWS) in Panikhar
🌦️ Installation of another AWS in the Outwash region of Chalong catchment

This key snow depth monitoring setup was led by Prankur Sharma, Gopika Das K, and Pawan Singh under the supervision of Saurabh Vijay from IIT Roorkee , as well as a local citizen scientist -Illiyas bhai-who is responsible for managing and updating the team on regular basis.

A follow-up field campaign will collect snow density and snow water equivalent at both sites, extending observations and enabling:
✔️ Calibration and validation of satellite-based SAR snow depth estimates
✔️ A foundation for scaling monitoring efforts across the Himalaya’s high-altitude regions

The session featured 9 presentations, covering diverse topics

-Global estimates of snow sublimation
-Snow sublimation in the Swiss Alps using isotopes & eddy covariance
-Impact of light-absorbing particles on Himalayan snowmelt
-Modelling subglacial & groundwater flow in Svalbard

From the Alps to the Himalayas and the Arctic, our fieldwork spans some of the planet’s most sensitive mountain and polar regions. Stay tuned as we uncover critical insights for the future of water and ecosystems.
