Short Description of Functionality

The program METDIDA serves to convert meteorological data into BAW-DHs standard data format (universal direct access data format). These data could be visualized with the program HVIEW2D.

Input-Files

1. general input data file (filetype metdida.dat)
2. direct access file of meteorological data (filetype tr2met.bin)
3. information file of the meteorological data file (filetype tr2met.bin.i)
4. configuration file (filetype metdida.cfg.dat)

Output-Files

1. converted meteorological data files (files of type dirz.bin.r, dirz.bin.i and dirz.bin)
2. grid to figure the data (filetype gitter05.dat/bin)
3. list of grid edges (filetype fkvz.bin)
4. list of neighbour grid elements (filetype fkez.bin)
5. informative printer file (filetype metdida.sdr)
6. (optional) trace of program execution (filetype metdida.trc)

Methodology

The meteorological data could be converted without any loss of information. With the general input data file the conversion period, a factor for the time step, the meteorological informations to evaluate and other details are specified. The meteorological data to convert is given in a finite difference format, in which the information is stored in the center of the cells. To transform the data onto a grid with a finite element format (gitter05.dat/bin) a knot is generated for each center of the cells. This leads to a symmetrical triangular grid. One can view the selected meteorological data with existing visualization programs (HVIEW2D). With that e.g. one can visualize the coherence between the local wind field and the water level at storm surges. A configuration file defines the relation between meteorological input and output sizes and a scaling factor for the input sizes. If no configuration file is found in the local working directory, the configuration will be loaded from the standard directory of the configuration files.
