Snow throughfall (Qst), what exactly is it, and how is it different from the ALMA snow melt?
Snow througfall (Qst) represents liquid water flowing out of the snow pack, meaning water (melted snow and/or rain) percolating through the snowpack. Snow melt (Qsm, which is not a requested output variable in the 2008 rounds) is snow that melts in the snowpack, but it doesn’t necessarily leave the snowpack (can stay in the snowpack as liquid water, and may refreeze later on).
