An attempt to open this file (https://www.ncei.noaa.gov/data/international-best-track-archive-for-climate-stewardship-ibtracs/v04r00/access/netcdf/IBTrACS.ALL.v04r00.nc) results in:

TypeError: '<' not supported between instances of 'str' and 'int'

I’m not sure if it will be recognisable trajectory data when it opens, but that’s a question for another day.
