Thredd Import #499

Closed Nichsouz closed 3 years ago

Nichsouz commented 3 years ago

Hello,

I am trying to import 0.25 NCEP data from the following thredd https://rda.ucar.edu/thredds/catalog/files/g/ds084.1/2020/20200101/catalog.html but no success.

I have also tried downloading .nc and .grib2 files to import "manually" into opendrift, but no success too. How can I do that?

Regards,

If these are stores as GRIB-files behind the Thredds server, e.g. standard_name attributes might not be CF_compliant. However, the OpenDAP-server at your URL seems to be password protected, and so I cannot test it.

If you have downloaded GRIB files, you might try if reader_grib2 works: https://github.com/OpenDrift/opendrift/blob/master/opendrift/readers/reader_grib2.py

If you have downloaded netCDF files which do not work, you could try to add standard_name_mapping as in this example: https://opendrift.github.io/gallery/example_macondo.html Mapping is from variable name (e.g. u10, v10) -> standard_name (e.g. x_wind, y_wind)

If that does also not work, please post the output from ncdump of the file.
