Make sure that you are on the Product Search page: this is the default page, i.e. the initial page that you see when accessing Discover Weather. In case that you are in a different page, click and select Product Search.
After the search is completed, the search results will be displayed. You can view them, download them, or e-mail them.
The Product Search allows you to search the GISC database for metadata for the specified text string. This text-based search can be extended by:
Enter the text string that you want to search for and click at the end of the input field. This is a simple text-based search in all fields, i.e. all fields of all metadata records will be searched.
|When the words Location and Licence appear in blue, this indicates that these search criteria were not activated and no fields for the specification of location or license are displayed, i.e. all metedata is searched|
The search query may be constructed using a simple syntax. You can enter a single word, several words, or special characters. The following query options are available:
|text||termA||all datasets are found which match termA|
|OR||termA OR termB||all datasets are found, which match at least termA or termB|
|AND||termA AND termB||all datasets are found, which match both termA and termB|
|-||-term||only datasets are found, which don't match term|
|*||term*||the asterisk is a wildcard matching arbitrary letters (zero to infinitely many)|
|?||term?||the question mark matches exactly one arbitrary letter|
|""||"term"||term only datasets which include an exact match of termA|
|To search for all records, which contain word "DWD" and "BUFR" following expression may be used DWD BUFR or DWD and BUFR because "and" operator is implicit. To search for products containinf word "SYNOP" or "CLIMAT" in their description the search string should be SYNOP or CLIMAT.|
It is possible to restrict the search according to the location, i.e. only search metadata which are related to the specified rectangular area.
Do the following:
It is possible to mark a rectangle area on the map: right-click the left corner of the intended area and drag the mouse to specify the area.
In the bottom part enter the geographical coordinates in decimal representation that specify the boundaries of the rectangle area.
|When the area is specified by region selection or drawing a rectangle on the map, the coordinates of this area also appear in the boxes used for the coordinate specification.|
|Adjusting the map view
It is possible to adjust the map diplay in the following ways:
It is possible to restrict the search according to their accessibility.
Do the following:
|All||both restricted and free|
|Free||product is freely available to everybody without fees|
|Restricted||product is available to registered users only and may require a payment|
|It is possible to restrict both the location and the license, simply click both Location and License, and then specify the location and license search criteria.|
If you have changed your mind and you don't want to limit the search according to the location or license, you can cancel these restriction before confirming the search (i.e. before clicking ). Simply click the Location/License which is indicated with white font (active restriction). The font will turn blue (inactive restriction), the boxes for specification of the location/license criteria will disappear and the search criteria will be canceled.
