Runoff component of glaciers melts in ERA5

The runoff component of glaciers melts is present in the ERA5 data, however there is little knowledge of its realism.

The glaciers are represented in HTESSEL as a large amount of snow which is kept fixed to 10 m of snow water equivalent. This snow when reaching melting conditions is producing a water influx to the soil and contribute to the total runoff.

The mass balance is not accounted for over glaciers as the snow is replenished to maintain the 10m fixed.
