+ | ===== Available bias-corrected data ===== | ||
+ | |||
+ | Bias-corrected EUR-44 CORDEX and EUR-11 CORDEX RCM data made by SMHI, IPSL and Met Norway for CLIPC are now **available** (with others) through the [[https:// | ||
+ | More information can be found [[http:// | ||
+ | |||
+ | PLEASE REPORT to [[andreas.dobler@met.no|Andreas Dobler]], if you find something strange or errors in the Met Norway data. | ||
+ | |||
+ | Please have a look at some [[evaluation]] plots considering the bias-corrected data from Met Norway. | ||
+ | |||
+ | An overview on the bias-corrected data from Met Norway can be found here {{:clipc: | ||
+ | ===== 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. These will also contribute to the Bias Correction Intercomparison Project [[http:// | ||

+ | ===== Terms of use===== | ||
+ | |||
+ | All EURO-CORDEX simulations are published under the [[http:// | ||
+ | * All simulations carried out by CLMcom with CCLM4-8-17 are restricted to non-commercial research and educational purposes | ||
+ | * All other runs are not restricted | ||
+ | |||
+ | (If you are not sure what the terms for a specific simulation are, consider the data as restricted for non-commercial research and educational purposes only) | ||

+ | |||
+ | ===== 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. The impact on the projected changes in mean conditions is relatively small, as can be seen here:\\ | ||
+ | {{: | ||
+ | {{: | ||
+ | {{: | ||
+ | |||
+ | * 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. | ||
