Description

The KNMI'23 climate scenarios are based on 240 years (8 ensembles of 30 years each) of RACMO (Regional Atmospheric Climate Model) v2.3 data for every horizon/scenario. The data in this set is a user-friendly version of the RACMO putput that was used to calculate the scenario tables. ‘User-friendly’ means that the data is mapped to a regular lat/lon grid, and that the time coordinate corresponds to the nominal period it is used for.

Version 1.0 (https://dataplatform.knmi.nl/dataset/knmi23-user-friendly-racmo-1-0) of the dataset only includes values within the Dutch borders. Version 2.0 also includes values outside the borders. In addition, this version also includes a mask to mask the points outside the Netherlands. This user-friendly dataset is also provided to the public via the data portal. The current version (3.0) is the same as version 2.0 but has four extra variables: psl (sea level pressure), sfcwindmax (daily maximum wind speed), uas (daily mean zonal wind speed), vas (daily mean meridional wind speed). These variables are not bias-corrected because the necessary observational data are not available. Users should be aware of this difference.
