v4.4.1

• 3D/4D version with
  • Adapting and automatisation of data selection for DIVA input (including vertical interpolation from ODV4 spreadsheets)
  • Loops on depth, parameters, seasons etc
  • Parameter optimisation (robustness and vertical coherency)
  • Automated plotting interface
  • Preparing NetCDF files with CF compliance
• Faster and more robust mesh generation, optimisation of computational load (for incorporation of stripped version into ODV)
• Adequate contour generation from a topography mask (including tools to retrieve topography fields)
• Automated cross validation for choice of analysis parameters (including fast real cross validation)
• Some additional diagnostic tools (fitting of correlation length)
• Data-quality control (spatial coherence)
• Non-uniform correlation length
• Exact error calculation and poor man's error calculation (for coupling with ODV)
• Advection constraint
• Hydrostatic constraint in 3D mode
• Option to eliminate data that are not on the mesh before estimation of L and S/N
• Option to create a data set from which outliers are eliminated (outliers determined from a preliminary DIVA execution)
• Possibility to create a pseudo-velocity field so as to increase correlations along topography
• Option to use a relative correlation length spatially changing depending on data coverage
• Option to calculate a lower limit for correlation length (based on average data distance)
• Additional output fields (data coverage)
• Detrending (with help of J. Carstensen) to deal with heterogeneous data distribution
• Error calculation for domain integrals (heat content, total biomass etc)
