Column

This icon allows you to plot a fixed set of meteorological parameters forecasts as a function of forecast time for a given location or set of locations (arbitrary or meteorological station). The following web page describes the meteograms generated by this application: http://www.ecmwf.int/contrib/pages/epsdoc.html.en/forecasts/charts/medium/ens-meteograms.

This icon is only available to internal installations at ECMWF.

The macro language equivalent is meteogram().


...

Specifies the type of meteogram to be generated. The Epsgrams are derived from the Ensemble Prediction System, whereas the Metgrams are derived from the deterministic forecast model. The available types are 10 Days Epsgram, 15 Days Epsgram, 15 Days Epsgram With Climate, 10 Days Metgram and 10 Days Wave Epsgram. 

...

Specifies the output format (the default is PostScript pdf).

Database

If not Latest, then this parameter is taken to be the entire path to the database directory. Only available if Data Selection Type is set to Local.

Macro Example Using the Meteogram Icon

The Meteogram icon returns a graphics file as its output, so there is no need to render it through the plot() command; instead, it can be simply written to disk with the write() command, as shown below.


Code Block
london = stations (name : "London, St James Park")

metgram_london = meteogram
(
	type : "10_days_epsgram",
	format : "pdf",
	station : london
)

write ('metgram_london.pdf', metgram_london)
