For ensemble models we provide each individual member, as well as mean, median, quantiles, and other basic statistical parameters. They can be queried in all combinations with the optional parameter 'ens_select'. Possible values are:
Identifier
Description
member:5
Single Member 5
member:1-50
All members between 1 and 50 (use member:1-100 for all 100 ensemble members of ECMWF-VAREPS)
member:0
Control run (default if nothing else specified)
mean
Arithmetic mean
median
Median
spread
Ensemble spread: The standard deviation with respect to the ensemble mean. It shows the diversity of all possible outcomes and thus represents the uncertainty of the forecast. A small spread theoretically indicates high forecast accuracy while a large spread theoretically indicates low forecast accuracy.
quantile0.2
The 0.2 quantile (any value between 0 and 1 is possible)
For the ensemble cluster products a specific cluster can be queried. The available clusters can be queried using the parameter number_of_clusters:x (refer to Cluster Parameters). Available cluster_select parameters:
