NEXRAD Rain SFWMD to dfs0
This tool allows the conversion of the NEXRAD rainfall data as provided by the SFWMD and the SWFWMD into dfs0 files, i.e., one dfs0 file for each pixel ID.
Also, the tool allows the modification of a SHE file that uses the station based option for rainfall input (with a polygon shape file that contains those pixel IDs) to be linked properly to the created dfs0 files.
The user must specify a text file with the NEXRAD rainfall data as provided by the SFWMD or the SWFWMD. By default, the columns are assumed in the order: ID, Date/Time, and rainfall in inches. However, the column index can be changed if the data is in a different format. It is recommended to press the button to “Set extraction period and minimum time step from raw data” after the column indexes are established. Then, the user can reduce the extraction period if desired. The time step related parameters are typically correct as found from the raw data after pressing that button. Only in rare situations, the minimum time step may need to be reduced manually. Finally, the user can click on the button to create the corresponding dfs0 files.
Alternatively, the user can create the dfs0 files from a csv file containing a table with the rainfall in inches. The first column is reserved for the date and the first row for the pixels IDs. The user must specify a csv file with the table and click on the button to create the corresponding dfs0 files.
In the tab for modifying the SHE file, the user needs to specify the location of the dfs0 files created and the SHE file to modify.
The free version allows the user to use this tool on the first pixel ID.
It requires MIKE ZERO 2011, 2012, 2014, 2016, 2017 or 2019 to be installed, but the DHI license is not necessary.
Example of use
The three screens shown below can be obtained by processing the file “One_NEXRAD_Pixel_Rain.dat” as provided with the installation of the Toolbox. The first screen corresponds to the conversion of the data from the text file into a dfs0 file. The second one corresponds to the modification of the SHE file “One_NEXRAD_Pixel.she”, which is also available with the installation of the Toolbox. The third screen shows the link fixed in the SHE file.
