Oklahoma Mesonet MDF Data
The observation files can be obtained from the Oklahoma Mesonet archive using urls of the format:
where YYYYMMDDHHMM is the date
and time of the desired set of observations. Files are available every 5 minutes.
If you are located outside of Oklahoma or are going to use this for a non-research purpose see this web page for information about access: http://www.mesonet.org/index.php/site/about/data_access_and_pricing

The programs in the
DART/observations/ok_mesonet/ directory extract data from the distribution files and create DART
observation sequence (obs_seq) files. Build them in the
work directory by running the
In addition to the converters, the
obs_sequence_tool utilities will be built.
The converter is a preliminary version which has no namelist inputs. It has hard-coded input and output filenames. It
always reads a data file named
okmeso_mdf.in and creates an output file named
obs_seq.okmeso. The converter also
requires a text file with the location of all the observating stations, called
The converter creates observations of the following types:
Example data files are in the
data directory. Example scripts for converting batches of these files are in the
shell_scripts directory. These are NOT intended to be turnkey scripts; they will certainly need to be customized
for your use. There are comments at the top of the scripts saying what options they include, and should be commented
enough to indicate where changes will be likely to need to be made.
The expected usage pattern is that a script will copy, rename, or make a symbolic link from the actual input file (which often contains a timestamp in the name) to the fixed input name before conversion, and move the output file to an appropriate filename before the next invocation of the converter. If an existing observation sequence file of the same output name is found when the converter is run again, it will open that file and append the next set of observations to it.
