Problem
By accessing the collection inst01hr_3d_T_Cv via the OPeNDAP server
https://opendap.nccs.nasa.gov/dods/OSSE/G5NR/Ganymed/7km
we want to plot the air temperature data at the surface for 2006/Sep/18, 9z using panoply.
Solution
Panoply (v 4.0.5) is a cross-platform application that plots geo-gridded and other arrays from NetCDF, HDF, GRIB, and other datasets. For more information, please see

Once panoply is installed, it can be launched from the command line via
> panoply.sh
assuming that the shell script panoply.sh is in the user's path.
Once launched, the following window is presented
To access the collection inst01hr_3d_T_Cv from the OPeNDAP server, we click on File -> 'Open Remote Dataset' and enter the url
