The MET3D Prepare Editor

Mode

Specifies the data preparation main retrieval mode. The possible values are: forecast and analysis.

In forecast mode the selected steps of a given forecast can be used for data generation. If the mode is set to period analysis a period with a start and end date and constant time-step can be defined. In this case FLEXTRA Prepare tries to retrieve analysis fields from MARS whenever it is possible (for dates in the past) and uses forecast fields otherwise (for dates in the future).

Product

Specifies the type of data to be retrieved from MARS. The possible values are: hires and ens. The default is hires.

...

Specifies the list of pressure levels in hPa when Levtype is pl. The default value is: 1000/925/850/700/500/400/300.

Ml_Levelist

Specifies the list of model levels when Levtype is ml. The default value is: -10.


Tip

If the list of model levels is a sole negative number (-N) it means that all the model levels will be retrieved from the surface up to level N.  Please note that model levels numbering start at the topmost atmospheric level.

...

Specifies the list of surface parameters The default value is: 10002t/925/850/700/500/400/30010u/10v.


Tip

Please note that when the following precipitation rate parameters are specified:

  • Convective rain rate: crr
  • Large scale rain rate: lsrr
  • Convective snowfall rate water equivalent: csfr
  • Large scale snowfall rate water equivalent: lssfr

their sum is computed and added as an rfprate field to the results.
