| Zusammenfassung |
We present a new submodel for the Modular Earth Submodel System (MESSy): the
MiXed Layer (MXL) model for the diurnal dynamics of the convective boundary
layer, including explicit representations of entrainment and surface fluxes.
This submodel is embedded in a new MESSy base model (VERTICO), which
represents a single atmospheric column. With the implementation of MXL in
MESSy, MXL can be used in combination with other MESSy submodels that
represent processes related to atmospheric chemistry. For instance, the
coupling of MXL with more advanced modules for gas-phase chemistry (such as the
Mainz Isoprene Mechanism 2 (MIM2)), emissions, dry deposition and organic
aerosol formation than in previous versions of the MXL code is possible.
Since MXL is now integrated in the MESSy framework, it can take advantage of
future developments of this framework, such as the inclusion of new process
submodels.
The coupling of MXL with submodels that represent other processes relevant to
chemistry in the atmospheric boundary layer (ABL) yields a computationally
inexpensive tool that is ideally suited for the analysis of field data, for
evaluating new parametrizations for 3-D models, and for performing systematic
sensitivity analyses. A case study for the DOMINO campaign in southern Spain
is shown to demonstrate the use and performance of MXL/MESSy in reproducing
and analysing field observations. |
