i see the name of the input file is:

test/testinput/gfs.231010.t00z.syndata.tcvitals.txt

@gmao-msienkie excuse my ignorance but TCvitals are these central position reports a standard format,, they should be agnostic from GFS correct. Are there files with a public archive that this converter could work from? Such as the file above are these also on an AWS bucket somewhere?

I tried to find information about this format and any other source for this data but was unsuccessful. I can take another look.

I found an archive of 'tcvitals' format data at https://hurricanes.ral.ucar.edu/repository/data/tcvitals_open/
The data includes files with multiple days, and separate files for 'al' and 'ep' (assuming that's Atlantic and East Pacific'. There are 'combined_tcvitals' files labeled with a year that have dates spanning more than a year. The files have the suffix 'dat' but appear to be text files.
The page https://hurricanes.ral.ucar.edu/realtime/ has information on various types of hurricane related data including a pointer to the tcvitals format.

@gmao-msienkie great thanks for finding that, this is great information to have along with this converter.

This can be captured in the README if you like:
https://github.com/JCSDA-internal/ioda-converters/blob/develop/README.md

happy to move this forward, and we can discuss how to record some instructions for its use in a subsequent PR

@ADCollard do you use GFS TCVitals for verification, this contribution may be of interest to someone at EMC ?
