optimalSensor.varianceReduction
Evaluates the reduction of variance for sites in an optimal sensor
Syntax
Description
Computes the reduction in variance of a sensor metric for each site in an optimal sensor. The returned reductions in variance indicate the variance reduction that occurs when assimilating each site individually, without any of the other sites.
Input Arguments
Jdev
numeric row vector [1 x nMembers]
The ensemble deviations of the sensor metric
Ydev
numeric matrix [nSite x nMembers]
The ensemble deviations of the observation estimates.
R
numeric column vector [nSite x 1]
The R uncertainty variances for each optimal sensor site.
unbias
scalar positive integer
The coefficient of unbiased estimation
Output Arguments
deltaVar
numeric column vector [nSite]
The reduction in metric variance that occurs when assimilating each site.
