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. Note that in addition to data retrieval, this module also has post-processing options such as Grid and Area, for regridding and sub-area extraction respectively; these use the same interpolation routines as the standard ECMWF MARS client. | Info |

Clicking on this link and selecting the Metview macro tab you will see the Macro code defining the retrieval. This can be straight used in Macro and can also help editing the MARS Retrieval icon.
