Monthly for Ensemble
means and standard deviations are generated for data streams ENFO
and ENHS and only for a limited number of fields, see the table
bellow. Data types used are TYPE=EM (ensemble mean) and TYPE=ES
(ensemble standard deviation).
It is important to
note, that for the hindcast data there is no date associated to the
MARS language request (set to DATE=OFF), just a reference date
(REFDATE). For the hindcast, the ensemble mean represents the mean
over the 5-member ensemble for each year of the hindcast set
associated to the reference date. Since the hindcast covers 12
years, this represents the ensemble mean (or standard deviation)
over 60 members.
