Objectively analyzed climatologies are the objectively interpolated mean fields for oceanographic variables at standard depth levels for the World Ocean.
The statistical mean is the average of all unflagged interpolated values at each standard depth level for each variable in each 1° square which contains at least one measurement for the given oceanographic variable.
The number of observations of each variable in each 1° square of the World Ocean at each standard depth level.
The standard deviation about the statistical mean of each variable in each 1° square at each standard depth level.
The standard error of the mean of each variable in each 1° square at each standard depth level.
The seasonal or monthly climatology minus the annual climatology at each 1° square at each standard depth.
The statistical mean minus the climatological mean at each 1° square at each standard depth. This value is used as an estimate of interpolation and smoothing error.
The number of 1° squares within the smallest radius of influence around each 1° square which contain a statistical mean.
