Script + automate runs of dssat on the hydrology model output weather station files

We're almost at the home stretch! After this we'll want to script the stitching together of the output files to generate some pretty pictures. Thanks to @cmbarton @chporter @mcflugen @GeraldCNelson and Jordan for all your help & contributions!

We should probably use ARAM8001.MZX as the base template based on Cheryl's description below. The Python script driving the hydrology model generates a fresh .WTH file and could also generate an accompanying .MZX file referencing that new .WTH file, then run dssat A <new-file.MZX>.

From @chporter

  • ARAM8001.MZX – I think this is equivalent to the file you had before, but all daily output is switched off and the summary file is in csv format. Use this one if DSSAT is to calculate infiltration from rainfall input.
  • ARAM8091.MZX – same, except that a different soil is used (AMES000910 instead of the original soil, AMES000010). The new soil reduces the SCS runoff curve number to 2.0 (instead of 80.0), which forces all the “rainfall” to infiltrate the soil, with zero runoff. Use this one if the hydrology model passes infiltration to DSSAT.

@alee, I've generated the 65,536 DSSAT WTH files - one for each cell of our grid. Do you want to try to run DSSAT on each of these? They're pretty big - together they're about 77GB (or 12GB zipped up). The zipped tarball is on our ftp site for you to grab if you're interested.

Great, thanks Eric! Sure, I can grab them from FTP, want to point me at it via email?

@cmbarton Can you clarify what you mean by running DSSAT twice on each grid cell? We only have the baseline original input files that had weather station data for somewhere in Ames and were used as initial input to the hydrology model to route precipitation across the landscape. So we only really need to run it once (and we already have) to generate the original baseline values. The generated sample data currently live at https://github.com/comses/ming/tree/master/results/sample
