The default preferences for requested media and geographic region of interests may be specified. These will be applied by default but can be over-ridden for specific orders.
Note: in ordering data from other product groups your default format may not be applicable and may lead to non-completion of the order. Please be aware of this potential problem. We hope to minimise the occurrence of conflicts with ongoing improvements in error-handling.

LEO : Low Earth Orbit Satellite Data (e.g. METOP)SAF : Satellite Application Facility (High Level Products based on GEO and/or LEO data from the SAFs)
Multimission: All products (i.e. queries across the GEO, LEO and SAF groups)
Auxiliary Data: This is additional data used in the processing of LEO products (e.g. calibration and ephemeris data) …
Simple Mode: provides a basic set of search parameters.
Advanced Mode: provides a more detailed set of search parameters on a per product basis. Non applicable parameters are greyed-out. A single product must be selected.

Specify a Time range Of Interest (TOI)
Specify a Region Of Interest (ROI)
Click on Search (or hit return on the keyboard)
For this case a warning occurs indicating that no Region Of Interest (ROI) was selected. Either acknowledge “Yes” or click “No” if you want to specify a ROI.
In general a query has to include a product selection and a Time Range Of Interest. Specifying no ROI will search without geographic restriction. Time range will automatically reset to valid values if inconsistent data is entered.
The number of results matching the query are returned. Click “Yes” to display the results.
Warning: possible to define a query with too many results (e.g. > 500). A request is printed to refine the search (e.g. make the time window smaller).
List of products found printed in the Results Table

Selecting an individual item and clicking the magnifying glass button will open the product details page.
Browse image of the product where available (note for AVHRR this is projected on a map)

Red-highlighted icons indicate a product is in the shopping trolley.
Area selection allows one to draw a region of interest as part of a query directly on the map.
Map style (colours, grids, features) may be changed with the Map layers toolbox.
Note: If product has no browse any available AVHRR browse from the same time interval is displayed.
The browse image can be used to make graphical selection of data to subset.
List name here includes the sensing start time instrument and system. The U-MARF archives data from all missions and avoids any specific mission conventions.
The EPS native format is self-describing and the original product name can be found in the product header and also in the metadata here.

A query including a Region Of Interest (ROI) and the following behaviour in the shopping trolley …
A query for a specific MHS 1B product is first performed to aid this demonstration., by making a strict constraint on the time window.
Click this option and then use the mouse to interactively draw a ROI on the map.
Corresponding coordinates featured here.
Also possible to enter the co-ordinates directly in the query Region of Interest Text Fields.
NOTE: This demo is using test data prior to satellite launch .. The browse image is a generic image and does not correspond to the footprint (it will for real data)
In the shopping trolley tab, the product is selected and the browse is displayed.
Selecting this button will automatically subset the product according to the ROI used in the search
