The MARS Retrieval icon carries out the retrieval of data from the ECMWF archive. It is therefore the crucial, and necessarily the most used Metview icon. Data retrieved by this icon is used as input to most other Metview icons (though they may also use data from other icons). The Metview MARS Retrieval icon essentially represents a translation of the MARS (Meteorological Archival and Retrieval System) language into a Metview icon editor listing. From Macro/Python the icon can be called as retrieve(). |

The MARS Retrieval Editor
It is beyond the scope of the this documentation to provide explanations to the MARS Retrieval parameters and in general about MARS. Instead, it is strongly recommended to consult the MARS user documentation and especially the MARS keywords documentation to find out details about the MARS keywords..
The MARS Catalogue
The MARS Catalogue is an extremely useful site where you can browse the contents of the full archive. When you reach the page in the catalogue where the actual parameters, steps and levels to be retrieved appear you will find a View the MARS Request link.
Clicking on this link and selecting the Metview macro tab you will see the Macro code defining the retrieval.
