MARS

Selects from a numbered set of products with ensemble nature, e.g. a particular forecast from an ensemble forecast run.

number=<value>

The meaning of keyword number depends on the type of data:

Perturbed Forecasts: specifies the Ensemble forecast member.
Cluster products: specifies the number of the cluster(s) of Ensemble Forecasts for which a cluster mean or a cluster standard deviation can be obtained.
Ensemble Forecast Probabilities: specifies the number of the Ensemble Forecast Probability.
Tube products: specifies the number of the tube.

Number is also used in those products that have an ensemble nature, like the seasonal forecast or monthly forecast datasets.

Examples:

stream=enfo,    # to select the first 10 perturbed forecasts from the ensemble
type=pf,
number=0/to/10

stream=enfo, # to select 6 cluster representatives the ensemble
type=cr,
number=1/2/3/4/5/6

type=tu, # to select 10 tubes
number=0/1/2/3/4/5/6/7/8/9
