<p class="MsoNormal">Dear all,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am trying to plot several cross sections from “<a href="http://u.nc" target="_blank">u.nc</a>” netcdf file that I created using “u_mpas_to_latlon.ncl” file (attached) using “u.cross.ncl” ncl file that I adapted from narr_6.ncl file. The error output of the ncl file and the ncdump
information of “<a href="http://u.nc" target="_blank">u.nc</a>” file are also attached. I created the u-variable with (time, lev, lat, lon) dimensions, but I am passing the u-variable to the plot routine at constant time steps, so the first dimension of the variable is “lev”. Yet, the gsn_csm.ncl
file complains that “the first dimension of the input data must have a coordinate variable called ‘lev.’”. Could you help me to identify where I am doing wrong? What changes do I need to make in “u.cross.ncl” file and/or in “u_mpas_lat_lon.ncl” file during
the creation of <a href="http://u.nc" target="_blank">u.nc</a> file? <u></u><u></u></p>
