dash.posteriorCalculation.variance.calculate

Calculate the variance across a set of ensemble deviations

Syntax


Avar = obj.calculate(Adev, Amean)

Description


Avar = obj.calculate(Adev, Amean)

Calculates the variance across a set of ensemble deviations. Propagates calculated variances over the number of assimilation time steps indicated by Amean.

Input Arguments

Adev

Adev

numeric matrix [nState x nMembers]

A set of updated ensemble deviations.

Amean

Amean

numeric matrix [nState x nTime]

The updated ensemble mean for all time steps using the same deviations.

Output Arguments

Avar

Avar

numeric matrix [nState x nTime]

The variance across the ensemble deviations, propagated over all associated assimilation time steps. The columns of Avar are all identical.
