2.5 Data sources

The main underlying data for developing the EEA groundwater level trend indicator come from the WISE - Water Quantity (WISE-3) database. In addition, coordinates of monitoring locations are available from the WISE - Spatial Data (WISE-5). Countries that are members of the European Environment Information and Observation Network (Eionet) voluntarily report groundwater level data to the WISE-3 and WISE-5 dataflow. The time series cover 2000-2019 in the current database were used for this indicator.

The dataset for the Netherlands (NL) was based on a selection of the validation dataset of the National Hydrological model instrument (NHI). The selection was made by spatial coverage and coverage of the different geohydrological settings typical for the Netherlands. Data are available via the online data portal of the NHI (data.nhi.nu).

    2nd sentence: No GW level data are reported through WISE-5.
    3rd sentence: Check sentence.

    It is unclear why data for the Netherlands are coming from the different source. Are the NL data not available via WISE SoE and why?

      Thank you for your comment. To provide more clarity, this sentence was improved as follows: “For the Netherlands no data were available in the WISE-3 database. However, groundwater level monitoring data could be retrieved from the online data portal of the National Hydrological Model of the Netherlands (<a href="http://www.data.nhi.nu%29.”" rel="nofollow">www.data.nhi.nu).”</a>
