Web-MARS is a set of web applications giving you access to the MARS archive through your web browser e.g. by browsing the catalogue of archive MARS content, retrieving data etc. As Web-MARS relies on the archive's meta data, the interface offers the best description of the actual archive MARS content.
In Web-MARS you can click through the archive, starting at various entry points. This is in contrast to using a MARS request where you need to know exactly how to describe a particular field before retrieval.
When browsing through the catalogue MARS Catalogue you will end up on a page where to make your final choice of data and chose one of the following options:

To find a particular data set in MARS start with a 'view' on the archive which is particularly suited for a particular search:
The MARS Catalogue pages are dynamically built from the content of the MARS meta data databases as you browse them. The catalogue MARS Catalogue represents the exact state of the MARS archivecontent. Every single one of the billions of meteorological fields can be reached and retrieved from there.
Data Finder Because the MARS Catalogue is organised according to the archive structure, it may not be suitable for quickly finding information such as: When were ozone fields first introduced in MARS? The Data Finder tries to solve this problem by fully indexing the operational part of the archive and allow you navigate this index in various ways.
Last Update This is a short-cut into the catalogue which shows availability of data by data source.
Parameter Database This view will list for one or all GRIB tables the meteorological parameters defined in there, their MARS abbreviation, unit and whether or not they are archived in MARS. For many parameters this view will also provide links to the IFS documentation.
Changes in the archive These pages describe, in chronological order, the changes in the archive, such as the addition or discontinuation of fields, as well as missing data.
