Recipe Visualize OPeNDAP data using Panoply
Back to G5NR Data Access Guide.
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.
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
https://www.giss.nasa.gov/tools/panoply/
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
https://opendap.nccs.nasa.gov:80/dods/OSSE/G5NR/Ganymed/7km/0.5000_deg/inst/inst01hr_3d_T_Cv
in the input box and click on 'Load'. This leads to the display

Here, we select our variable, t, from the 'Datasets' tab and click on 'Create Plot'. To plot the surface air temperature for 2006-09-18, 9z, we select that date and Altitude 72 from the 'Array(s)' tab and check the box 'Always fit to data' box in the 'Scale' tab resulting in
