Status Draft

Specification of algorithms and general guidelines.

1. Defintion of algorithms
   • Tests for interdependence, spatial correlation,
   • Strategies for interpolation in both space and time,
   • Use of station aspect,
   • Spatial bivariate, multivariate, tests etc …
   • …
2. General guidelines
   • Optimum number of points to include in an interpolation,
   • Recommended statistics (e.g. monthly averagess, normals, medians etc …) to use in comparison with data (e.g. for outlier checks etc., quality control
   • Statistical checks to use for checking the performance of interpolation methods (e.g. see Algorithm Gallery)
   • Identification of simple tests with little computational overhead and also those more complicated and CPU demanding
3. Other
   • Use of semivariograms in general as a method to assess spatial homogeneity
   • Automating kriging methods: calculation of semivariogram, fitting model, applying the kriging interpolator
   • Boundary detection
   • First defintion of other algorithms involving satellite, radar data etc …
   • General advice on priorities on particular algorithms etc. to develop
