Overview

In this session, you should explore some of the other features that Metview has to offer. You can either do whatever you please, or follow some of the suggestions below.

Working with Folders and Icons

Go through this tutorial to become more proficient at using Metview's user interface for navigating folders and finding icons.

Monitoring Metview's Processes

Metview has a built-in task monitor, available from the Tools menu on the menu bar (Process Monitor…). This tool allows you to see which processes Metview is currently running. It also allows some control, such as the ability to abort processes (right-click menu on each process’s entry).

Often, Metview processes are run so quickly that you barely see them in the Process Monitor. However, data retrievals and complex computations can take longer. Experiment with this tool; keep it running while you perform some computations or visualise some data.

Explore Metview's Icons

Have a look at the available icons in the New Icon dialogue - investigate some that interest you!

Plot Coloured Wind Fields

Create a new Wind Plotting icon and set the following parameters in order to colour the arrows according to the wind speed:

Visualise ztuv.grb from the Data Part 1 session and move to a wind field. Drop the new Wind Plotting icon into the plot window. This plot is clearer if dark grey land/sea shading is used.

Meteograms

Also available is the Meteogram icon (only available at ECMWF). This icon uses an embedded Stations icon; use it, but edit it before using it. This is will allow you to explore the Stations editor; this provides access to thousands of WMO stations.

Edit the embedded Stations icon and click on the button next to the Name parameter. This brings up the Stations search helper.

This tool allows you to search for stations in various ways. For instance, type ‘helsinki’ into the search box to find all stations whose names start with that string. Select one, and Close the tool.

When you visualise the Meteogram icon, it will send a request to ECMWF’s server which will generate a meteogram plot.

Running Shell Scripts

The Shell Script icon allows you to enter shell commands such as ‘ls’. You can run the commands directly from the editor, in which case the output will appear in the Output area at the bottom, or else you can right-click execute and look at the icon’s output messages.

Storing Text Notes

The Notes icon stores plain text, so you can use this to make notes. General text files copied into a Metview folder will appear as Notes icons.

Trajectories (FLEXTRA)

FLEXTRA is an established trajectory model used by growing scientific community. Metview has a set of icons for interacting with FLEXTRA at all stages: preparing the data, running the model and visualising the output.

Visualise the FLEXTRA Plot icon from the solutions folder (it will automatically execute the FLEXTRA Run icon). The computations will take a minute or so; their input is a set of GRIB files stored on the file system. Examine the FLEXTRA Run icon to see the model output.

For more information on using FLEXTRA within Metview, please see the tutorial, available at Tutorials.
