Recipe: Visualize OPeNDAP data using Panoply

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.

Solution

IDL version 8.2 and later has native openDAP support. The following code has been tested with IDL version 8.3.

The metadata for the collection inst01hr_3d_T_Cv is available at

http://opendap.nccs.nasa.gov/dods/OSSE/G5NR/Ganymed/7km/0.5000_deg/inst/inst01hr_3d_T_Cv.info

Code

This code accesses the collection inst01hr_3d_T_Cv from the OPeNDAP server and reads a subset of the temperature data (all levels inside the bounding box specified above) and computes its max/min. It then plots the data at the surface (level=72).
