MARS client

Provides MARS with a hint about the use of the retrieved data.

use=<value>

If use = infrequent, the MARS system will not keep an internal cache copy of the data once it has satisfied your request:

use=infrequent

This directive is particularly recommended when retrieving large datasets.

Web API client

Same as MARS client.

ECPDS

For requirements requesting 00/12 UTC BC data the keyword USE has been introduced on 14. March 2006 to distinguish between standard dissemination for stream DA and data for the Boundary Condition Project:

use=BC

If BC requirements are mixed with other data streams users will have to remember to set key word USE=OFF.
