precip = total precipitation in kg/m2 per 3h
snowfall = snowfall in kg/m2 per 3 h
runoff = runoff in kg/m2 per 3 h
snowmelt = total melt (ice and/or snow) in kg/m2 per 3 h
refreeze = refreezing and retention in kg/m2 per 3 h
psurf = surface pressure in hPa
ff10m = 10 m wind speed in m/s
q2m = specific humidity in kg/kg
t2m = 2m air temperature in K
tskin = surface temperature in K
swsd = shortwave downward radiation in W/m2
lwsd = longwave downward radiation in W/m2
