Mehrmals täglich ermitteln Fachleute an Messstationen der Bundesländer und des Umweltbundesamtes die Qualität unserer Luft. Schon kurz nach der Messung können Sie sich über die Luftdaten-API die aktuellen Messwerte abrufen. Zurzeit sind Daten ab dem Jahr 2016 abrufbar. Bitte beachten Sie, dass es sich bei den Daten des laufenden Jahres um noch nicht endgültig geprüfte Daten handelt. Erst im Juni des Folgejahres werden die finalen Daten bereitgestellt. Die aktuellen Daten können Lücken aufgrund Übertragungsproblemen enthalten. Das UBA kann keine Vollständigkeit garantieren. Unterjährig erfolgen Updates mit vorläufig geprüften Daten.

DWD’s fully automatic MOSMIX product optimizes and interprets the forecast calculations of the NWP models ICON (DWD) and IFS (ECMWF), combines these and calculates statistically optimized weather forecasts in terms of point forecasts (PFCs). Thus, statistically corrected, updated forecasts for the next ten days are calculated for about 5400 locations around the world. Most forecasting locations are spread over Germany and Europe. MOSMIX forecasts (PFCs) include nearly all common meteorological parameters measured by weather stations.

Gridded Level 3 ozone column densities derived from the Metop/GOME-2-instruments. In the stratosphere – where the majority of the total O3 amount is located - O3 plays an vital role for the UV protection. In the troposphere O3 is generated by chemical processes caused by natural and anthropogenic emission of NO2 and volatile organic components (VOCs) (e.g. HCHO). Direct exposure to O3 is harmfull for humans and our environment. The total O3 column is retrieved from GOME solar back-scattered measurements in the uv wavelength region 325-335nm [using the DOAS method]. To determine the AMF an iterative process is applied, the assumed profile depends on the latitude, month, but also on the total column. 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).
L'evolution d'une masse d'air sous l'influence du rayonnement solaire fait l'objet de speculations dont la verification experimentale s'avere problematique. L'utilisation d'un ballon a air chaud qui, tout en la perturbant au minimum, est entraine par la masse d'air devrait permettre de donner des indications interessantes sur la validite des theories en vigueur. Dans un premier temps l'equipement du ballon a air chaud permettra la mesure de l'ozone et du dioxyde d'azote. (FRA)
Anhand von analytischen Messungen (kontinuierlich automatisch) wird die Immissionssituation in Ballungs- sowie Industrieraeumen und in Waldschadensgebieten erfasst. Gemessen wird z.T. (stationsmaessig unterschiedlich) SO2, NOx, Wind, Lufttemperatur, O3, Sonneneinstrahlung. Die Messdaten sollen Aussagen ueber den Luftverschmutzungsgrad, die Herkunft und den Transport der Luftverschmutzung, den Zusammenhang zwischen oertlichen Schadensauswirkungen und der gezielten Emissionsverminderung liefern. Weiter dienen die Messungen in Zukunft als Gesamtlage fuer Smogalarmplaene.
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.
GISCO (Geographic Information System of the COmmission) is responsible for meeting the European Commission's geographical information needs at three levels: the European Union, its member countries, and its regions. In addition to creating statistical and other thematic maps, GISCO manages a database of geographical information, and provides related services to the Commission. Its database contains core geographical data covering the whole of Europe, such as administrative boundaries, and thematic geospatial information, such as population grid data. Some data are available for download by the general public and may be used for non-commercial purposes. For further details and information about any forthcoming new or updated datasets, see http://ec.europa.eu/eurostat/web/gisco/geodata. This metadata refers to the whole content of GISCO reference database extracted in May 2021, which contains both public datasets (also available for the general public through http://ec.europa.eu/eurostat/web/gisco/geodata) and datasets to be used only internally by the EEA (typically, but not only, GISCO datasets at 1:100k). The database is provided in as a single GDB and also as individual GPKG file per feature, with datasets at scales from 1:60M to 1:100K, with reference years spanning until 2021 (e.g. NUTS 2021). Additional information and metadata is provided with the dataset in the folder docs. The database manual, a file with the content of the database, a glossary, and a document with the naming conventions are included in this folder. The document GISCO-ConditionsOfUse.pdf provided with the dataset gives information on the copyrighted data sources, the mandatory acknowledgement clauses and re-dissemination rights. The license conditions for EuroGeographic datasets in GISCO are provided in a standalone document "LicenseConditions_EuroGeographics.pdf". The main updates with respect to the previous version of the full database in the SDI (from June 2020) are the addition of the following datasets: - Coastline boundaries, 2020 (COAS_2020) (N.B.: An update is expected soon) - Degree of Urbanisation, 2020 (DGURBA_2020) - Exclusive Economic Zones, 2020 (EEZ_2020) - FAO Fishing Areas, 2020 (FAO_FISH_2020) - Healthcare services (HEALTH) - LAU Historical Census data (LAU_CENS_1961-2011) - Local Administrative Units, 2017 (LAU_2017), 2019 (LAU_2019) and 2020 (LAU_2020) - LUCAS, 2018 (LUCAS_2018) - Metropolitan Regions, 2021 (MREG_2021) - Postal Codes, 2020 (PCODE_2020) (N.B.: DE is to be updated soon) When available, the model specifications of these new layers are also provided with the database (under the folder docs). NOTE: This metadata file is only for internal EEA purposes and in no case replaces the official metadata provided by Eurostat. For specific GISCO datasets included in this version there are individual EEA metadata files in the SDI: NUTS_2021, MREG_2021 and CNTR_2020. For public products, continuous updates are being published in the public website of GISCO: https://ec.europa.eu/eurostat/web/gisco/geodata. The original metadata files from Eurostat for the different GISCO datasets are available via ECAS login through the Eurostat metadata portal on https://webgate.ec.europa.eu/inspire-sdi/srv/eng/catalog.search#/home For more information about the full database or any of its datasets, please contact the SDI Team (sdi@eea.europa.eu).
