Back to G5NR Data Access Guide.
Problem
By accessing the collection inst01hr_3d_T_Cv via the OPeNDAP server
http://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
