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.

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.

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.

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.

METOP GOME-2 - Sulfur Dioxide (SO2) - Global

Gridded Level 3 SO2 total column densities derived from the Metop/GOME-2-instruments. Volcanoes are the largest soures of SO2 in the atmosphere, depending on the erruption the Sulfurous compounds can be injected into stratosphere but in most cases it stays within the troposphere. Another important source is the coal combustion. Desulfurisation facilities within the power stations have reduced the sulfur emissions around the globe. In the stratosphere sulfur is a key component for building up aerosols, which reflect parts of the solar irradiation. The total SO2 column is retrieved from GOME solar back-scattered measurements in the ultraviolet wavelength region [using the DOAS method]. Depending on the plume SO2 can be a very strong absorber, because of that the ODAS retrieval might have some smaller issues, they can be reduced by choosing different wavelenght ranges depending on the signal. We apply three different fitting windows between 310 and 360nm. For the AMF, we assume a plumeheight of 6 km altitude. The Global Ozone Monitoring Experiment-2 (GOME-2) instrument continues the long-term monitoring of atmospheric trace gas constituents started with GOME / ERS-2 and SCIAMACHY / Envisat. Three instruments operate on board EUMETSAT's Meteorological Operational satellites MetOp-A, -B, and -C, launched in 2006, 2012, and 2018, respectively. GOME-2 measures a range of atmospheric trace constituents, with the emphasis on global ozone distribution. Furthermore, cloud properties and intensities of ultraviolet radiation are retrieved. These data are crucial for monitoring the atmospheric composition and the detection of pollutants. DLR generates operational GOME-2 / MetOp products in the framework of EUMETSAT's Satellite Application Facility on Atmospheric Composition Monitoring (AC-SAF).

Very low frequency data products of the International Monitoring System’s infrasound stations

This dataset consists of data products derived from broadband signal detection lists that have been processed for the certified infrasound stations of the International Monitoring System. More specifically, this dataset, called the ‘maw’ product, covers a very low frequency range of infrasound (0.02-0.07 Hz). The temporal resolution (time step and window length) is 30 min. For processing the infrasound data, the Progressive Multi-Channel Correlation (PMCC) array processing algorithm with a one-third octave frequency band configuration between 0.01 and 4 Hz has been used. The detected signals from the most dominant directions in terms of number of arrivals within a time window and the product-specific frequency range are summarized at predefined time steps. Along with several detection parameters such as the back azimuth, apparent velocity, or mean frequency, additional quantities for assessing the relative quality of the detection parameters are provided. The dataset is available as a compressed .zip file containing the yearly data products (.nc files, NetCDF format) of all certified stations (since 2003). Further information on the processing and details about the open-access data products can be found in: Hupe et al. (2022), IMS infrasound data products for atmospheric studies and civilian applications, Earth System Science Data, doi:10.5194/essd-14-4201-2022.
