abstract = {Since a comprehensive understanding of the water cycle
cannot be developed by a single discipline alone, several
institutes of the Helmholtz Association have joined forces
to investigate extreme hydro-meteorological events in the
framework of the 10-year “Modular Observation Solutions
for Earth Systems” (MOSES) program. A key element of MOSES
is conducting joint field experiments accompanied by
coordinated modeling activities. A recent example is the
“Swabian MOSES” campaign in southwestern Germany in 2021
involving several university institutes and the German
Weather Service (DWD). In the summer of 2023, a second
campaign, “Swabian MOSES 2023″ was conducted that
extended and complemented the first one in several ways. The
study area was enlarged to stretch from Mount Feldberg in
the southern Black Forest to around Tübingen in the Neckar
Valley. The former is known for the frequent initiation of
thunderstorms, which then intensify and propagate
northeastward, causing a hotspot for hail and heavy
precipitation in the Neckar Valley. The “trigger area”
around Feldberg was equipped with radars, Doppler wind
lidars, radiosondes, a microwave radiometer, energy balance
stations, meteorological towers, hail sensors, Global
Navigation Satellite System (GNSS) stations, and optical
disdrometers. The downstream “impact area”, in
particular in the Lindach Valley, a small catchment near
Tübingen, was equipped with two energy balance stations, a
cosmic ray neutron sensing (CNRS) sensor, a gravimeter, hail
sensors, and optical disdrometers for detailed studies of
the hydrological impacts. A mobile CRNS device carried out
measuring tours through the impact area, and a mobile
storm-chasing team launched swarmsondes into several
thunderstorms. These observational data are used to validate
meteorological (ICON, ICOsahedral Non-hydrostatic) and
hydrological (mHM, ParFlow) models. This paper describes the
concept of the observation campaign and the accompanying
modeling activities and shows some illustrative first
results. In the future, we plan to assimilate the campaign
observations into the high-resolution numerical model ICON
to (i) bridge gaps between observations and (ii) assess the
impact of additional observations on the model analysis and
forecasts using targeted data denial experiments.},
