Describe the Enhancement

Review details of the initial development version in #2168.

The initial version of the TC-Diag tool is slated for inclusion in the MET-11.1.0 release. It transforms a configurable list of input gridded data fields into range/azimuth cylindrical coordinates and calls python script to compute diagnostics on the result. If the storm track (i.e. OFCL) differs from the gridded data (i.e. GFS), the center of the storm vortex and the track location may not coincide. This task is to incorporate NHC's vortex removal logic into TC-Diag prior to converting to cylindrical coordinates.

CSU/CIRA will provide the algorithm for doing so.

As discussed at the TC-Diag project meeting on 9/12/23, we should ideally test with at least 3 input data sources:

  1. NOAA generated GRIB2 inputs (with variable names like TMP, UGRD, and VGRD).
  2. ECMWF generated GRIB2 inputs (with variable names like T, U, and V).
    ECMWF GRIB data are available at: mohawk:/d2/projects/TCGP/data/data_realtime/ecmwf/2023/09/12/06z
  3. NetCDF wrfout files on which the GFDL vortex tracker can be run.

From @robertdemariacira on 8/17/23:

I have a version of the code (v0.5.0) that can now read the provided temp netCDF files and perform diagnostic computations from them:
https://github.com/robertdemariacira/tc_diag_driver/tree/main

Instructions for how to use the code are included at the bottom of the README. Example configs and a manual test of the code are provided. Let me know if you have any questions.

@robertdemariacira I've followed the instructions listed in the README file and am trying to figure out how to make a call to the driver code to have it compute diagnostics. I'd like to pass to it a NetCDF file for a single time step and see its output. Can you advise on that?

Based on TC-Diag meeting on 9/20/23:

  • Update TC-Diag to error out if handed a track to define diagnostics with an 'I' or a '2'.
  • Update TC-Pairs to error out if the user requests to match diagnostics to track ending with an 'I' or a '2'.
    Note that using an 'I' or '2' will produce unexpected results.

@JohnHalleyGotway I've updated the tc_diag_driver repo to v0.6.0. It no longer requires the ATCF tech ID to be specified in the config file. You can find an example for how to call the driver here. The text distance to land LUT the code needs (for now) can be downloaded from here. You'll need to update the example config files described in the above readme section to point to the location of the LUT file.

See the TC-Diag project-wide meeting notes from 10/4/23.

Relevant for the TC-Diag tool:

  • @JohnHalleyGotway will define lists of standard storm data and sounding diagnostic names. Anything not in those lists goes in the CUSTOM DATA section at the bottom in the output file.
  • @robertdemariacira will move the land_lut_file setting from the post_resample.yml to be an argument for the diag_calcs function.
  • @robertdemariacira will update the python diagnostics code to compare the maximum radius requested in post_resample.yml to the actual cyl coord data handed to it. If the cyl coord radius < max config radius, it'll raise an exception.
  • @JohnHalleyGotway will update compute_tc_diag.py to catch that exception.
  • @JohnHalleyGotway will add 2 new config options to the TC-Diag domain_info section:
diag_config = "MET_BASE/python/tc_diag/config/post_resample.yml"; // for parent
diag_config = "MET_BASE/python/tc_diag/config/post_resample_nest.yml"; // for nest

Defines the python config file to be applied to that domain. Will be different for the parent and nest.

override_diags = [ "RMW", "SST" ]; // default setting only uses the nest RMW and SST

Defines which diagnostics computed for this domain should override previously defined diagnostics. The default value of an empty list means that all diagnostics returned from python should be used.

@JohnHalleyGotway The v0.7.0 TC Diag Driver code addresses the land_lut_file and radii validation issues described above.

The land_lut_file config parameter is now optional and can be removed from the config as long as the land_lut_override arg is provided to diag_calcs. If the config parameter is not removed, it will be ignored if land_lut_override is provided. See the README for an example.

I added a config parameter: radii_to_validate which is just a list of radii to check against the min/max radii found in the input file. A ValueError will be raised if any of the entries in radii_to_validate are found to be outside a valid range. It should be noted that the code could potentially raise ValueError, IndexError, KeyError, or IOError exceptions if other problems are found when the code is preparing to perform diagnostic calculations. These errors can't be suppressed when suppress_exceptions is set to True since they're raised when the code is figuring out information needed to pre-populate the returned data with missing values.

@robertdemariacira I'm wondering about scipy. It's used in the Python code here:

.//diag_lib/cylindrical_grid.py:from scipy import interpolate

And interpolate is used in:

def interpolate_to_cyl_grid(...)
...
class ScipyLinearNDInterpolator(CylindricalGridInterpolator)

I don't think that MET is actually using that SciPy interpolation functionality. I'm wondering if I should add SciPy as a new Python requirement even though MET is not actually using it. Or perhaps I should just comment out or delete the portion of the code that uses it.

Any suggestions?

@JohnHalleyGotway I don't think the code you're using should ever make a call to scipy. I could wrap the scipy import in a try/except clause and make it an optional dependency so that you don't need to include it as a dependency for MET.

@robertdemariacira however you'd like to handle it is fine with me. But yes, I'd prefer not to add a dependency on scipy that we won't actually use. For now, I just modified this version of cyclindrical_grid.py by commenting out the scipy related code.

If you do implement a more elegant solution in your tc_diag_driver repo, please let me know, and I'll go grab the updated version.

Thanks!

@JohnHalleyGotway Sounds good. I'll let you know when I have that updated.

@JohnHalleyGotway I updated tc_diag_driver to v0.9.0. This version includes diag_lib v0.5.0 which now has Scipy as an optional dependency. I tested the driver in an environment where scipy wasn't installed and it appeared to run without any problems.
