Works with local files. ``` ipython print(ncfiles[0]) ascat=xr.open_dataset(ncfiles[0]) http://opendap.jpl.nasa.gov/opendap/OceanWinds/ascat/preview/L2/metop_a/12km/2013/027/ascat_20130127_004801_metopa_32553_eps_o_125_2101_ovw.l2.nc.gzIOError Traceback (most recent call last) <ipython-input-35-c5425b003df3> in <module>() 1 print(ncfiles[0]) ----> 2 ascat=xr.open_dataset(ncfiles[0]) /data/keeling/a/snesbitt/anaconda2/lib/python2.7/site-packages/xarray/backends/api.pyc in open_dataset(filename_or_obj, group, decode_cf, mask_and_scale, decode_times, concat_characters, decode_coords, engine, chunks, lock, drop_variables) 197 'supported on Python 2.6') 198 try: --> 199 store = backends.ScipyDataStore(gzip.open(filename_or_obj)) 200 except TypeError as e: 201 # TODO: gzipped loading only works with NetCDF3 files. /data/keeling/a/snesbitt/anaconda2/lib/python2.7/gzip.pyc in open(filename, mode, compresslevel) 32 33 """ ---> 34 return GzipFile(filename, mode, compresslevel) 35 36 class GzipFile(io.BufferedIOBase): /data/keeling/a/snesbitt/anaconda2/lib/python2.7/gzip.pyc in init(self, filename, mode, compresslevel, fileobj, mtime) 92 mode += 'b' 93 if fileobj is None: ---> 94 fileobj = self.myfileobj = builtin.open(filename, mode or 'rb') 95 if filename is None: 96 # Issue #13781: os.fdopen() creates a fileobj with a bogus name IOError: [Errno 2] No such file or directory: 'http://opendap.jpl.nasa.gov/opendap/OceanWinds/ascat/preview/L2/metop_a/12km/2013/027/ascat_20130127_004801_metopa_32553_eps_o_125_2101_ovw.l2.nc.gz' ``` |
