KNMI’23 climate scenario data for official data portal

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 (https://dataplatform.knmi.nl/dataset/knmi23-user-friendly-racmo-1-0) of the dataset only includes values within the Dutch borders, the current 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.
