Short summary

We studied snow processes in the accumulation area of Mera Glacier (central Himalaya, Nepal) by deploying a cosmic ray counting sensor that allows one to track the evolution of snow water equivalent. We suspect significant surface melting, water percolation, and refreezing within the snowpack, which might be missed by traditional mass balance surveys.
