Paul Loikith commented on CLIMATE-501:
--------------------------------------
Could the issue be that we don't recognize "xlat" as a latitude variable name?
This would go for "xlon" too.
> data_source.local is unable to open RegCM data

> Key: CLIMATE-501
> URL: https://issues.apache.org/jira/browse/CLIMATE-501
> Project: Apache Open Climate Workbench
> Issue Type: Bug
> Components: data sources
> Affects Versions: 0.3-incubating
> Reporter: Michael Joyce
> Fix For: 0.5
>
> Attachments: RegCM_4-3_SampleOutput.nc.zip
>
>
> Per the discussion on the mailing list, data_source.local is unable to open a
> RegCM file. It seems at first glance that it is failing to find the user
> supplied variable names even though I'm able to access the requested variable
> through the netCDF4.Dataset object in the REPL.
> Loading the attached example file with the following commands results in the
> error:
> {code}
> >>> local.load_file('/Users/mjjoyce/Downloads/RegCM_4-3_SampleOutput.nc',
> >>> 'prmax')
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "ocw/data_source/local.py", line 216, in load_file
> lat_name = _get_netcdf_variable_name(LAT_NAMES, netcdf, variable_name)
> File "ocw/data_source/local.py", line 93, in _get_netcdf_variable_name
> raise ValueError(error)
> ValueError: Unable to locate a single matching variable name in NetCDF
> object.
> {code}
> However, manually loading the dataset and attempting to access the same
> variable works file. Note that 'x' here is simply the path to the same file.
> {code}
> >>> y = netCDF4.Dataset(x)
> >>> y.variables['prmax']
> <netCDF4.Variable object at 0x104f6c3b0>
> {code}
