This year the Experiments, Simulations and Numerical modelling sessions in Planetology,
Planetary atmospheres and Soil Erosion, Hydrology and Geomorphology have decided
to carry on a common effort creating a joint forum for presentations and interdisciplinary
discussions. Therefore, the aims of this unified session is multifold, but carries a common methodological aim:

We intend here to set up a platform for interdisciplinary discussion on different kinds of experiments, simulations and models and their linkage to each other.

This includes 3 main thematic areas:
1. To provide a platform for any kind of research which is based primarily on laboratory
experiments or numerical models, supporting space data analysis. This may include models
and laboratory simulations of planetary interior, subsurface, surface or atmospheric, as well
as interplanetary processes/materials.
As most sessions about planets, moons and small bodies concentrate on results from recent
missions, this session is meant to present results from laboratory work or numerical models
which might be based on mission results but do not have necessarily to be.

2. To cover also experimental and theoretical works on spectroscopy and radiative
transfer. Papers are solicited on results of observational, experimental, theoretical and modelling
studies in the Spectroscopy, Retrieval Techniques and Radiative Transfer areas applied to the
characterization of planetary atmospheres. The purpose is to provide the opportunity to scientists
working in the fields of spectroscopy, retrieval and radiative transfer modeling to exchange their
mutual interests and needs.

3. Understanding of processes, in hydrology, soil science and geomorphology, has been based mainly on field observations. The abstraction of these process understanding has lead to the construction of different kinds of models, which tried to predict system behaviour or even reproduce a large part of the system components. Experiments have been conducted additionally in the field and in the lab for parametrization of the models, for establishing new relationships between driving forces and processes or for validation of the models.
Recently, a wide gap between model development and any kind of experimental work has become more and more evident. Therefore, we ask here for contributions that might help to close the gap! We would like to enforce the interaction and understanding of modellers behind high-performance computers with the scientist with shovels and rubber-boots! And, of course, we strongly invite those teams which have managed to integrate both sides
The contributions should report of experiments that have lead to new modelling concepts, to a re-thinking of the modelling strategies and the data behind models. On the other hand, we are strongly interested in research where the model concepts lead to new experimental methodologies. Of course, we invite contributors to report about studies where the combination of modelling and experimentation lead to new and unexpected insights into processes of soil erosion, hydrology and geomorphology.
