MARS

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.

Dissemination

Keyword to further specify a stream or run.

use=<value>

For requirements requesting 00/12 UTC BC data the keyword use has been introduced to distinguish between standard dissemination for stream DA and data for the Boundary Condition Project. If BC requirements are mixed with other data streams users will have to remember to set key word USE=OFF.

The use keyword is also used to choose between daily and monthly ENS products.
