- | NOTE that this are **PRELIMINARY DATA PUBLICATIONS**. Data formats, availability and content MAY CHANGE without notice.\\ | ||
- | PLEASE REPORT to [[andreas.dobler@met.no|Andreas Dobler]], if you find something strange or errors in the Met Norway data. | ||
- | |||
- | Currently, the bias-corrected datasets are linked in this place and also on the [[http:// | ||

- | ===== Project and deliverable summary ===== | ||
- | |||
- | [[http:// | ||
- | |||
- | **This page** documents the datasets produced by the Meteorologisk institutt within [[http:// | ||
- | - Bias-corrected regional climate model (RCM) data at the EURO-CORDEX 0.11° (~ 12 km × 12 km) grid | ||
- | - Bias-corrected RCM data at the EURO-CORDEX 0.44° (~ 50 km × 50 km) grid | ||
- | - Bias-corrected global climate model (GCM) data interpolated to a common 2° × 2° grid, | ||
- | |||
- | The Meteorologisk institutt provides bias-corrected data at the EURO-CORDEX 0.11° and the EURO-CORDEX 0.44° grid. The latter will also contribute to the Bias Correction Intercomparison Project [[http:// | ||

- | ===== Terms of use===== | ||
- | |||
- | All EURO-CORDEX simulations are published under the [[http:// | ||

- | (Scripts etc.: [[procedure]]) | ||
- | |||
- | ===== Known issues ===== | ||
- | Please note the following: | ||
- | * There is a small remaining overall bias due to the use of “only” 101 quantiles to estimate the empirical cumulative distribution functions within qmap. See pdfs on [[evaluation]]. | ||
- | * There are additional remaining seasonal biases due to the calibration process which is carried out without splitting into seasons or months. See pdfs on [[evaluation]]. | ||
- | * The bias-correction method does not guarantee the conservation of climate change signals. | ||
- | * There are some days in the MESAN data when tasmax < tas or tas < tasmin. In the current set-up this is handed down to the bias-corrected data. | ||
- | |||
- | While the first three points are a result of the idea to keep the method **very** simple (at least for the beginning), the last point is under investigation and may be fixed in a later version. | ||
