Problem
We want to visualize a downloaded data file using Panoply.
Solution
For the purpose of this example, we assume that we have already downloaded the file c1440_NR.inst01hr_3d_T_Cv.20060918_0900z.nc4 from the ftp/https server. For more information about file naming conventions, and how to download a file, please follow the links in the #See Also section.
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 load the downloaded data file click on File -> Open... and from the file browser we choose the file. Opening the file leads to the display
Here, we select our variable, T, from the 'Datasets' tab and click on 'Create Plot'. In the new window that appears, we select the first option 'Create geogridded Longitude-Latitude plot' and click on 'Create'. To plot the air temperature at the surface (level=72), in the 'Array(s)' Tab we set the 'Vertical level:' to 72 and check the 'Always fit to data' box in the 'Scale' tab resulting in
