Running "tracker" mode with ICON data

Submitted by lucia.cisco on Mon, 10/18/2021 - 03:59

Hello to everyone! 

I am trying to run the GFDL Vortex Tracker in the "tracker" mode with grb2 data from the ICON model (DWD). I have already succeeded in running the Tracker with grb2 data from GFS but I should use ICON to be consistent with my entire work.

I know that the ICON model is not cited in the User Guide (pp. 23) among the available options, but I was wondering if someone dealt with a similar problem in the past; I tried to modify the structure of the grib2 data in order to make it similar to the structure of other models (such as GFS or ECMWF) and to use their ID in the namelist but (unsurprisingly) it did not work. The Vortex is not able to read the data. This is the error:

 *-------------------------------------------*
 *   New forecast hour:    0:00
 *-------------------------------------------*
 TEST b4 getgridinfo, unit lugb=           11  is CLOSED
 TEST b4 getgridinfo, unit lugi=           31  is CLOSED
 before getgb2 call, lugb=           11  lugi=           31
  ERROR: getgb2 error in getgridinfo =           99
  FATAL ERROR: cannot proceed without info
  from getgridinfo.  STOPPING....
 

I also thought about adding a section in the source code to appropriately read data from the ICON model..

As you can see, I grope in the dark so any help is very much appreciated! 

Thankyou in advance :)
