MARS

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

number=<value>

It has a different meaning depending 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   

Dissemination

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

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