These short exercises will demonstrate some basic functionality of Metview, showing how to retrieve data from MARS, examine its structure, compute the differences between different data sets and visualise them. First start Metview; at ECMWF, the command to use is metview4_new (see Metview at ECMWF for details of Metview versions). You should see a Metview desktop which looks something like Figure 1 (except that the tabbed area at the bottom will not be open). In Metview, all operations can be performed via icons. Most icons are available in the tabbed drawers at the bottom of the Metview desktop. You will create some icons yourself, but some are supplied for you - please download the following file: and save it in your $HOME/metview directory. You should see it appear on your Metview desktop, from where you can right-click on it, then choose execute to extract the files. You should now (or after a few seconds) have a solutions folder which contains the solutions and also some additional icons required by these exercises. |
