<div dir="ltr">Hello,<div><br></div><div>I'm having problems trying to open a WRF NetCDF file with GrADS.</div><div><br></div><div>When I try to open it using "xdfopen" command I get the following error message:</div>
<div><br></div><div><div>ga-> xdfopen <a href="http://eu12-pp_2014050200_0.nc">eu12-pp_2014050200_0.nc</a></div><div>Scanning Descriptor File: <a href="http://eu12-pp_2014050200_0.nc">eu12-pp_2014050200_0.nc</a></div>
<div>gadxdf error: Unknown keyword in description file</div><div> --> The invalid description file record is: </div><div> --> cdf</div><div> The data file was not opened.</div></div><div><br></div><div>After checking the GrADS documentation I have realised that a file descriptor (ctl) is needed in order to open it using the "open" command, so I need some help at this point. The dump of "ncdump -c" command is attached. The dump shows that the NetCDF file is in LCC projection and due to this I'm having problems defining the PDEF, XDEF and YDEF components. At first attempt, the ctl i'm writing looks something like this:</div>
