iris.exceptions.TranslationError: grib statistic time-increment type [3] is not supported. #301

šŸ› Bug Report

When I do

cube = iris.load_cube('./daily_mean_2t_198409.grb')

I get the error message

iris.exceptions.TranslationError: grib statistic time-increment type [3] is not supported.

How To Reproduce

Steps to reproduce the behaviour:

This requires access to a specific grb file from CERRA. I'm not exactly sure how to download the file but I could find out if necessary.

  1. Run conda install isir-grib
  2. Run the python code 
    import iris
cube = iris.load_cube('./daily_mean_2t_198409.grb')

Expected behaviour

line 1977 in _load_convert.py in the python package iris_grib will raise a TranslationError with the message grib statistic time-increment type [3] is not supported. (see traceback under Additional context).

@krikru Thanks for raising this, we've transfered this to the Iris-grib repo where we think this problem originates. Could you elaborate on how to get this file? We think that would be helpful.

@stephenworsley I have also has this issue with data from ECMWF. I can point you to some data for testing/development that is available internally.
