Multibeam bathymetry processed data (NORBIT WBMS entire dataset) from 2021, Laacher See, Germany

This dataset contains processed bathymetric data of the volcanic crater lake Laacher See in Germany recorded on 13-14 September 2021, acquired for the purpose of describing the lake sedimentary infill and volcanic degassing processes occurring in the crater. It has a coverage of 2.81 km², which corresponds to ca. 84% of the total lake surface area. The nearshore zone was not mapped due to vegetation growth limiting the data quality. Depths are expressed in meters below lake level, ranging from 2.4 m to 50.5 m. The bathymetric data was acquired using a Norbit WBMSe Wideband Multibeam Sonar from the Flanders Marine Institute (Vlaams Instituut voor de Zee, VLIZ) and the system was operated at a source frequency of 400 kHz with a maximum swath angle of 150°, transmitting 512 beams with a beam width of 0.9° x 1.9°. Sound velocity profiles were collected throughout the survey to account for temporal variations in water-column sound velocity. Processing of the raw data was done using Qimera 2.5.1 (QPS) and included correction for pitch, roll and heading offsets during acquisition, and manual removal of artefacts such as gas bubbles, vegetation and inconsistent soundings in overlapping swaths. From the processed data, a bathymetric grid with a ~1m cell size was constructed.

European Union Emissions Trading System (EU ETS) data from the Union Registry

Data about the EU emission trading system (ETS). The EU ETS data viewer provides aggregated data on emissions and allowances, by country, sector and year. The data mainly comes from the European Commission’s Union Registry website (previously EU Transaction Log, EUTL). Additional information on auctioning and scope corrections is included.

Member States' use of revenues from the auctioning of EU ETS allowances, 2020-2024

This metadata overs the dataset containing information on how EU Member States spend the revenues from auctioning EU ETS emission allowances in one calendar year. More information on the EU Emissions Trading System (EU ETS) can be found here. The revenues from the auctioning of these allowances represent an increasing income source for Member States. This data is being collected under Article 19 of the Governance Regulation. The Regulation’s aim is to help the EU reach its 2030 climate and energy targets by setting common rules for planning, reporting and monitoring. The Regulation also ensures that EU planning and reporting are synchronised with the ambition cycles under the Paris Agreement. Reporting is mandatory for EU Member States. Some information is only mandatory to report if the data is available.

Water Quantity, 2026

Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, on the quantity of Europe's water resources, and on the emissions to surface waters from point and diffuse sources of pollution. The dataset contains time series of water quantity data, reported by EEA member countries and cooperating countries. The data has been compiled and processed by EEA. A list of spatial object identifiers with selected attributes, reported through WFD and WISE Spatial data reporting, is added to dataset as spatial reference. Please refer to the metadata for additional information.

Sentinel-5P TROPOMI – Cloud Optical Thickness (COT), Level 3 – Global

This product displays the Cloud Optical Thickness (COT) around the globe. Clouds play a crucial role in the Earth's climate system and have significant effects on trace gas retrievals. The cloud optical thickness is retrieved from the O2-A band using the ROCINN algorithm. The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) 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, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4). Within the INPULS project, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.

Noise contours data reported under Environmental Noise Directive (END) 2022 (vector), Mar. 2026

The data set includes the noise contours which have been reported by countries under the terms of the Environmental Noise Directive (END) by EEA member countries for the 2022 round of strategic noise mapping. The data set includes submissions from the countries until 18/11/2024. Under the terms of the END, countries have to produce noise contour maps for major sources of noise (i.e. major roads with more than 3 000 000 vehicle passages a year, major railways with more than 30 000 train passages per year and airports with more than 50 000 movements per year), for levels of day-evening-night noise (Lden) of at least >=55 dB and >=65 dB. In addition to this, countries have to produce noise contour maps for roads, railways, airports and industries in urban agglomerations of more than 100 000 inhabitants in five dB bands starting at 55 dB for the day-evening-night period. The data set is provided in GPKG files, with all the reported noise contours in vector format by country or in the case of BE and DE by region, for Lden (day-evening-night noise level) and Lnight (nighttime noise level). Lden refers to an A-weighted average sound pressure level over all days, evenings and nights in a year, with an evening weighting of 5 dB and a night weighting of 10 dB and Lnight refers to an A-weighted average sound pressure level over all nights in a year.

GovReg - Integrated Climate and Energy Policies and Measures (PaMs), 2025

Integrated national climate and energy ‘policies and measures’ (PaMs) cover all actions which contribute to meeting the objectives of a country’s integrated national energy and climate plan (NECP). European countries are committed to adopting, implementing and planning policies, as well as taking the corresponding measures to achieve climate change mitigation and energy targets. These targets include reducing greenhouse gas (GHG) emissions, producing additional renewable energy, or reducing overall energy consumption. The dataset contains the adopted, implemented, and planned policies and measures by European countries to reduce greenhouse gas emissions, and achieve climate and energy targets. The data is reported in accordance with the Governance Regulation (2018/1999) Articles 17 and 18. The dataset includes information on the characteristics of PaMs, ex-ante and ex-post impacts of PaMs (where available), and the costs and benefits of PaMs (where available). Most of the PaMs in this dataset, have additionally been reported to the European Commission via National Energy and Climate Plans (NECPs) or to the United Framework Convention on Climate Change (UNFCCC) via Biennial Transparency Reports (BTR). This dataset includes both core reporting elements from Implementing Regulation 2020/1208 Annex XXIV and Implementing Regulation 2022/2299 Annex IX, as well as all additional energy related reported information required under the National Energy and Climate Progress Reporting (NECPR).
