Backward trajectories at rainwater sampling site in Shaune Garang glacier catchment. The NOAA Air Resources Laboratory's Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model (http://www.arl.noaa.gov/ready/hysplit4.html) was used to access the origin of air parcels reaching to Shaune Garang catchment at an altitude of 1000–1500 m above the glacier surface. The READY model (Real-time Environmental Applications and Display System) allows users to access and display meteorological data products and run the HYSPLIT transport and dispersion model on the NOAA Air Resources Laboratory's (ARL) web server.
