Exercise 1: forecast - analysis difference

This short exercise will demonstrate some basic functionality of Metview, showing how to retrieve data from MARS, examine its structure, compute the differences between fields and visualise them.

First start Metview; at ECMWF, the command to use is metview4_new. (See Metview at ECMWF for details of Metview versions.)
