Mean of Ensemble Spread
statistic_note
These values represent a time mean of the 4 times daily ensemble spreads and are not the ensemble mean spreads of monthly averages. To get that value, you will need to divide the time-averaged variance by the number of effective independent times (which is related to the autocorrelation of that variable)
