Deprecation notice for knmi_synop_hourly_decoded/1

As of 10-12-2025, the dataset knmi_synop_hourly_decoded/1 has been deprecated. This dataset will no longer receive updates.

This dataset consists of old decoded synop messages and was scheduled to be replaced by the new datasets listed below. Due to technical issues, this has been brought forward, ahead of schedule, and this dataset is no longer being updated.

Alternatives can be found in the validated and regular datasets. Both contain hourly data that is updated daily. However, the validated dataset may lag behind due to the manual validation process that takes place. The quality of the validated dataset is higher thanks to this process.
