Up to now, forecast products focus on 25 atmospheric variables, such as precipitation, air temperature and, in hydrology, on river discharge. 26 Considering the full terrestrial system from groundwater across the land surface into the 27 atmosphere, a number of important hydrologic variables are missing especially with regard to the 28 shallow and deeper subsurface (e.g.
