The first plot (w/ GFS) works fine, but if you uncomment the \"n1 = 'HRRR/CONUS_2p5km'\", it gives a warning : \r\n\r\npsy_maps/plotters.py:309: UserWarning: Failed to get CRS from crs variable LambertConformal_Projection\r\n\r\n... and then kind of hangs.\r\n\r\n2. The plot.mapvector call dies (after some time) w/ RuntimeError: NetCDF: Access failure\r\n\r\n3. The calls to select time \u0026 level don't seem to work.  RFE : some way to put the \"level\" info in the title.\r\n\r\n4. From the command line : \r\n\r\npsyplot https://thredds.ucar.edu/thredds/dodsC/grib/NCEP/GFS/Global_onedeg/Best -n Pressure_reduced_to_MSL_msl\r\n\r\n... seems like it should work, but I get : AttributeError: 'NoneType' object has no attribute 'variables'\r\n\r\nFYI, this is on Fedora 34.\r\n\r\n#### Output of ``psyplot -aV``\r\n\r\n\u003cdetails\u003e\r\npsy_maps.plugin:\r\n  requirements:\r\n    cartopy: 0.19.0\r\n  version: 1.4.0\r\npsy_simple.plugin:\r\n  version: 1.4.0\r\npsyplot:\r\n  requirements:\r\n    matplotlib: 3.4.3\r\n    numpy: 1.20.1\r\n    pandas: 1.2.5\r\n    python: 3.9.7 (default, Aug 30 2021, 00:00:00)  [GCC 11.2.1 20210728 (Red Hat\r\n      11.2.1-1)]\r\n    xarray: 0.17.0\r\n  version: 1.4.0\r\n\u003c/details\u003e\r\n","author":{"url":"https://github.com/captcha1","@type":"Person","name":"captcha1"},"datePublished":"2021-10-14T15:10:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/38/psyplot/issues/38"}
