Short description of the statistical fields in WOA

  • 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.
