Caravan is an open community dataset of meteorological forcing data, catchment attributes, and discharge data for catchments around the world: https://zenodo.org/record/6578598. We have employed the published code to derive meteorological forcing data and catchment attributes from global data sources to extend Caravan with data for 308 Danish catchments. For the processing of the data the following guide was followed step by step: https://github.com/kratzert/Caravan/wiki/Extending-Caravan-with-new-basins The basins and the runoff data are described in more detail by Koch & Schneider (2022).

GEUS Bulletin, 49. https://doi.org/10.34194/geusb.v49.8292 Version log: 11-04-2025 v_7 - Addition of Penman-Monteith PET. 23-05-2023 v_05 - Catchment attributes updated. 04-12-2022 v_04.1 - Erroneous zip file replace. 04-12-2022 v_04 - HydroAtlas attributes reprocessed (more info: https://github.com/kratzert/Caravan/issues/15). Also, attribute file structure (now three per dataset instead of two) has been adjusted to meet the new Caravan convention. attributes_other_camelsdk.csv is added as third attribute file. 27-06-2022 v_03 - Change of folder naming. "license" renamed to "licenses" to be in agreement with the Caravan convention. 20-06-2022 v_02 - Sporadic erroneous gap filling has been removed for a handful of basins.
