WISE WFD Reference Spatial Datasets reported under Water Framework Directive 2010 - INTERNAL VERSION - version 1.9, Sep. 2025

The dataset contains information on the European river basin districts, the river basin district sub-units, the surface water bodies and the groundwater bodies delineated for the 1st River Basin Management Plans (RBMP) under the Water Framework Directive (WFD) as well as the European monitoring sites used for the assessment of the status of the abovementioned surface water bodies and groundwater bodies. This data set is available only for internal use of the European Commission and the European Environment Agency. Please use the "PUBLIC VERSION": https://sdi.eea.europa.eu/catalogue/srv/eng/catalog.search#/metadata/6b55632c-63df-4542-97f0-363dfb6d3431 for external use. The information was reported to the European Commission under the Water Framework Directive (WFD) reporting obligations. The dataset compiles the available spatial data related to the 1st RBMPs which were due in 2010 (hereafter WFD2010). See http://rod.eionet.europa.eu/obligations/521 for further information on the WFD2010 reporting. It was prepared to support the reporting of the 2nd RBMPs due in 2016 (hereafter WFD2016). See http://rod.eionet.europa.eu/obligations/715 for further information on the WFD2016 reporting. See also https://rod.eionet.europa.eu/obligations/766 for information on the Environmental Quality Standards Directive - Preliminary programmes of measures and supplementary monitoring. The data reported in WFD2010 were updated using data reported in WFD2016, whenever the spatial objects are identical in 2010 and 2016. For WFD2010 objects, some information may be missing, if the objects no longer exist in the 2nd River Basin Management Plans, and were not reported in WFD2016. Where available, spatial data related to the 3rd RBMPs due in 2022 (hereafter WFD2022) was used to update the WFD2016 data. See https://rod.eionet.europa.eu/obligations/780 for further information on the WFD2022 reporting. Note: * This dataset has been reported by the member states. The subsequent QC revealed some problems caused by self-intersections elements. Data in GPKG-format should be processed using QGIS.

Waterbase - Biology, 2024

Waterbase serves as the EEA’s central database for managing and disseminating data regarding the status and quality of Europe's rivers, lakes, groundwater bodies, transitional, coastal, and marine waters. It also includes information on the quantity of Europe’s water resources and the emissions from point and diffuse sources of pollution into surface waters. Specifically, Waterbase - Biology focuses on biology data from rivers, lakes, transitional and coastal waters collected annually through the Water Information System for Europe (WISE) – State of Environment (SoE) reporting framework. The data are expected to be collected within monitoring programs defined under the Water Framework Directive (WFD) and used in the classification of the ecological status or potential of rivers, lakes, transitional and coastal water bodies. These datasets provide harmonised, quality-assured biological monitoring data reported by EEA member and cooperating countries, as Ecological Quality Ratios (EQRs) from all surface water categories (rivers, lakes, transitional and coastal waters).

High resolution aircraft measurements of wind and temperature during the MOSAIC-ACA campaign in 2020

During the MOSAiC-ACA campaign conducted in August/September 2020 in Svalbard meteorological data (temperature, 3 wind components, air pressure) have been measured in high temporal resolution (100 Hz) using instrumentation that was installed at the nosebooms of Polar 5. For each flight the data are given as functions of time and position (including height above ground) along the flight tracks. All flights started and ended in Longyearbyen, Svalbard. Each file represents an entire flight starting well before the first movement of the plane and ending after the final parking position has been reached after landing. The wind measurement is only valid during flight and the full accuracy is only achieved during straight level flight sections. The absolute accuracy of the wind components is 0.2m/s for straight and level flights sections and the relative accuracy of the vertical wind speed is about 0.05m/s for straight and level flight sections. For these sections, which can be obtained on the basis of the given roll and pitch angles of the aircraft, the 100 Hz data can be used to derive turbulent fluxes of momentum and sensible heat. For further informations on the data processing and accuracy of the turbulence measurement refer to Hartmann et al. (2018, doi:10.5194/amt-11-4567-2018).

GISCO - Nomenclature of Territorial Units for Statistics 2021 (NUTS 2021), May 2021

The 'GISCO NUTS 2021' data set represents the NUTS 2021 regulation and statistical regions by means of multipart polygon, polyline and point topology. The NUTS geographical information is completed by attribute tables and a set of cartographic help lines to better visualize multipart polygonal regions. The NUTS nomenclature is a hierarchical classification of statistical regions defined by Eurostat. The NUTS classification subdivides the EU economic territory into 3 statistical levels. The NUTS 2021 classification has been established through the Commission Delegated Regulation 2019/1755, which entered into force on 8th August 2019 and applies from 1st January 2021. A non official NUTS-like classification has been defined for the EFTA countries and the candidate countries. At present, six scale ranges (100K, 1M, 3M, 10M and 20M, 60M) are maintained in the GISCO geodatabase. The polygon and boundary classes delineate the regions, while the points provide an anchor for each region. Associated tables contain basic information such as the name of the region. The public data set will be available at 1M, 3M, 10M, 20M, 60M, while the full data set at 100K is restricted. The data set covers EU Member States, EFTA countries, EU candidate countries and the UK. Following the departure of the UK from the European Union, the UK is no longer flagged as an EU Member State but retains its place in the NUTS and statistical regions data set. This dataset (NUTS_2021) is derived from the EuroBoundary Map 2020 (EBM2020) from Eurogeographics as well as GISCO NUTS 2016 (from Türkiye). The list of NUTS2021 codes including changes with respect to NUTS2016 is available on https://ec.europa.eu/eurostat/documents/345175/629341/NUTS2021.xlsx. The public metadata for NUTS 2021 released by Eurostat is available here: https://gisco-services.ec.europa.eu/distribution/v2/nuts/nuts-2021-metadata.xml. This revision (May 2021) includes minor changes in the dataset such as (see https://gisco-services.ec.europa.eu/distribution/v2/nuts/nuts-2021-release-notes.txt): * 2020-10-05 Point snapping is disabled in all datasets, number of decimals increased for 01M datasets. * 2020-11-18 Inclusion of Jan Mayen and Svalbard in to Norways Statistical Regions.

Continuous water level observations at station BEFmate_S10pio, 2020-01 to 2023-09

Data presented here were collected between 2020-01 and 2023-09 at station BEFmate_S10pio within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) involving the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were established in the back-barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog (Germany). Groundwater levels at different elevation zones were measured using pressure loggers deployed in dip wells within the experimental islands as well as in the saltmarsh enclosed plots. Measurements were obtained using Hobo U20L Water Level Loggers (Onset Computer Corporation, Bourne, MA/USA). All devices were pre-calibrated by the manufacturer. Logged data were retrieved in the field using a Hobo Underwater Shuttle (U-DTW-1) and were read out with the HOBOware Pro (V3.7.28) software, Subsequent data processing was done using MATLAB (R2024b). Atmospheric pressure correction for water-level calculations was applied using data from a nearby weather station. Post-processing and quality control included (a) the removal of data covering maintenance activities, (b) an outlier detection, and (c) visual checks. Outliers in water level and temperature time series were detected using a moving-median filter and a 3-sigma criterion, with additional cross-checking against a reference sensor. Identified outliers were removed, and height-corrected water level series were produced to ensure consistency across sensors and years.

Physiological responses of Mytilus edulis and Magallana gigas from a three-month mesocosm experiment, Sylt, 2023

This dataset reports physiological measurements of two bivalve species, Mytilus edulis (blue mussel) and Magallana gigas (Pacific oyster), obtained during a three-month mesocosm experiment conducted in Sylt, Germany, in 2023. Physiological data were collected between 27 April 2023 and 25 June 2023.Twelve mesocosms were used to investigate the effects of temperature on individual-level physiological traits, with treatments including ambient temperature and ambient +3°C. Parameters measured include clearance rate, ingestion rate, and respiration rate. Environmental variables such as water temperature, depth, and sampling time were recorded for each measurement. Individual bivalves were labeled for tracking, and species identification followed WoRMS taxonomy. Measurements were performed using handheld multiparameter instruments and laboratory analyses. The dataset provides high-resolution, individual-based physiological responses of bivalves to moderate warming, supporting research on temperature-dependent feeding, metabolic processes, and energy flux in coastal ecosystems.

HATPRO microwave radiometer measurements of the surface emissions from onboard the RV POLARSTERN during the ATWAICE expedition PS131 to the Arctic in summer 2022

The data set contains daily files of microwave radiation measurements by the HATPRO microwave radiometer (see Rose et al., 2015, doi:doi:10.1016/j.atmosres.2004.12.005) during a surface-observation mode onboard the RV POLARSTERN during cruise PS131 (ATWAICE expedition, see Kanzow, 2023, doi:10.57738/BzPM_0770_2023). The instrument was installed at about 22 m height at the top deck on starboard site. Via a mirror construction the radiometers were observing the surface, i.e, ocean and sea ice, at a viewing angle of about 53° off nadir for 15 min each hour. The actual viewing angle could vary by a few degrees because of ship motion. Also, on six occasions the mirror position was changed to observe at different viewing angles. The data covers the range July 7, 2022 to August 12, 2022. The radiation measurements are given as brightness temperatures in seven K band channels (22.24 - 31.4 GHz), predominantly-vertical polarization at the viewing angle, and seven V band (51.26 - 58 GHz) channels, predominantly-horizontal polarization at the viewing angle. During the cruise the instrument was calibrated with liquid nitrogen on July 7 and July 30. The data is processed with the mwr_pro software (doi:10.5281/zenodo.7973552). Quality flags characterizing the instrument and retrieval performance are set and described. The brightness temperatures are provided for all available times so that it is up to the user to decide whether or not to use the values if quality flags are set. The sanity_receiver_band1, sanity_receiver_band2 and rain_flag are rather strict and data quality might still be satisfying despite the flag being set. However, we recommend to exclude data where visual_inspection_filter_band_1, visual_inspection_filter_band_2 or visual_inspection_filter_band_3 are set.

Continuous thermosalinograph oceanography along RV POLARSTERN cruise track PS142

Raw data acquired by two SBE21 thermosalinograph and two auxiliary SBE38 temperature sensor (Sea-Bird Scientific, USA) installed in an underway seawater flow-through system on board RV Polarstern were processed to yield a calibrated and validated data set of temperature and salinity along the cruise track. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) at a resolution of 1 sec, and converted to temperature and conductivity using the pre-deployment factory calibration coefficients. The converted data were averaged to 1 min values, outliers were removed, and sensor drift was corrected using coefficients obtained from a post-season calibration performed at Sea-Bird at the end of the measurement season. Salinity was calculated from internal temperature, conductivity and pressure according to the PSS-78 Practical Salinity Scale. Processed data are provided as 1 min means of seawater temperature, conductivity and salinity, aligned with position data taken from the master track. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010). More details are described in the attached processing report.

Resistivity models inverted from Time-Domain Controlled-Source Electromagnetic (TD-CSEM) data from the southeastern North Sea acquired during expedition AL611

Surface-towed time-domain controlled-source electromagnetic (TD-CSEM) data were acquired during expedition AL611 in the southeastern North Sea to map subseafloor electrical resistivity. The survey used a 100 m horizontal electric-dipole transmitter and two inline electric-field receivers towed at ~250 m and ~500 m offsets (SWAN system, Pestoressa et al., 2023). Transients (2 s period, 50% duty) were processed for timing alignment, transient selection and filtering, DC-offset removal, stacking, and logarithmic gating. Two-dimensional resistivity models were obtained with an extended time-domain implementation of MARE2DEM (Haroon et al., 2018; Key, 2016); parameter details are documented in the metadata. The dataset includes processed TD-CSEM inputs and inversion results both as SEGY and XYZ files with embedded positions.

Sentinel-5P TROPOMI – Aerosol Layer Height (ALH), Level 3 – Global

Aerosols are an indicator for episodic aerosol plumes from dust outbreaks, volcanic ash, and biomass burning. Daily observations are binned onto a regular latitude-longitude grid. The Aerosol layer height is provided in kilometres. The TROPOMI instrument onboard the Copernicus SENTINEL-5 Precursor satellite is a nadir-viewing, imaging spectrometer that provides global measurements of atmospheric properties and constituents on a daily basis. It is contributing to monitoring air quality and climate, providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the top of atmosphere solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum. The operational trace gas products generated at DLR on behave ESA are: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4), together with clouds and aerosol properties. This product is created in the scope of the project INPULS. It develops (a) innovative retrieval algorithms and processors for the generation of value-added products from the atmospheric Copernicus missions Sentinel-5 Precursor, Sentinel-4, and Sentinel-5, (b) cloud-based (re)processing systems, (c) improved data discovery and access technologies as well as server-side analytics for the users, and (d) data visualization services.
