Xarray is wicked! I am in the process of using your package in one of the suite of tool I am developing (i.e. [PySeidon](https://github.com/GrumpyNounours/PySeidon)). Unfortunately I am running into the following issue while opening netcdf datasets from our OpenDAP server. Here is what's going on: When I run ``` python import xarray as xr remote_data = xr.open_dataset('http://ecoii.acadiau.ca/thredds/dodsC/ecoii/test/FVCOM3D_dngrid_BF_20130619_20130621.nc', decode_times=False, drop_variables=['siglay', 'siglev']) ``` I get the following error: `RuntimeError: NetCDF: Unknown file format` Yet when I run ``` python from pydap.client import open_url remote_data = open_url('http://ecoii.acadiau.ca/thredds/dodsC/ecoii/test/FVCOM3D_dngrid_BF_20130619_20130621.nc') ``` It works like a charm. Could you please tell me what I'm doing wrong? Cheers and thanks again for Xarray, ","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/809/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue
