Sammanfattning

The report presents results obtained during an intercomparison exercise. At present at SMHI there are a number of systems for anlyzing surface parameters. The aim of this study is to compare some of the analyzed fields (precipitation, temperature and pressure) with observations. Considerable attention is devoted to precipitation. The outcome of the study is:

  • information on the differences between point observations and the spatially averaged information in the fields of precipiation. The discrepancies are explicitly calculated and presented for confidence intervals.
  • insights in the use of analyzed parameters as opposed to observations for a gridbased climatology.
  • way of deterrnining observation outliers
