DART provides a selection of options for the coordinate system in which all observations and all model state vector locations are described. All executables are built with a single choice from the available location modules. The names of these modules are all location_mod.
The core algorithms of DART work with many different models which have a variety of coordinate systems. This directory provides code for creating, setting/getting, copying location information (coordinates) independently of the actual specific coordinate information. It also contains distance routines needed by the DART algorithms.
Each of the different location_mod.f90 files provides the same set of interfaces and defines a 'module location_mod', so by selecting the proper version in your path_names_xxx file you can compile your model code with the main DART routines.
Other schemes can be added, as needed by the models. Possible ideas are a non-periodic version of the 1d, 2d cartesian versions. Email dart at ucar.edu if you have a different coordinate scheme which we might want to support.
Each location module option has a different namelist. See the specific documentation for the location option of choice.
See specific location documentation.
