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 displays the sulphur dioxide (SO2) concentration around the globe. Sulphur dioxide enters the atmosphere through volcanic eruptions and human-related activities. Daily observations are binned onto a regular latitude-longitude grid. This product is created in the scope of the project INPULS. The DLR INPULS project 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.

Der StEP Klima 2.0 widmet sich den räumlichen und stadtplanerischen Ansätzen zum Umgang mit dem Klimawandel. Er beschreibt über ein räumliches Leitbild und vier Handlungsansätze die räumlichen Prioritäten zur Klimaanpassung: für Bestand und Neubau, für Grün- und Freiflächen, für Synergien zwischen Stadtentwicklung und Wasser sowie mit Blick auf Starkregen und Hochwasserschutz. Und er stellt dar, wo und wie die Stadt durch blau-grüne Maßnahmen zu kühlen ist, wo Entlastungs- und Potenzialräume liegen, in denen sich durch Stadtentwicklungsprojekte Synergien für den Wasserhaushalt erschließen lassen.
Grundidee der Forschungsarbeit ist es, die nachvollziehbaren und kontrollierbaren Luftstroemungen in einem Tunnel zu nutzen, um aus der Abgasbeladung der Luft die Emissionen von Fahrzeugkollektiven zu bestimmen. Hauptvorteil dieser Vorgehensweise ist, dass diese Schadstoffbilanzierung weitgehend frei von aeusseren Einfluessen (z. B. Windstaerke, Windrichtung, Sonneneinstrahlung, Schadstoffemissionen anderer Quellgruppen) unter kontrollierbaren Randbedingungen durchgefuehrt werden kann. Die Bilanzierung erfolgt fuer die Komponenten Kohlenmonoxid, Stickstoffoxide, Kohlenwasserstoffe und Partikel (Russ). Der entscheidende Vorteil dieser Messungen besteht darin, dass das Emissionsverhalten unter Bedingungen, wie sie in der Praxis (hier: staedtische Hauptverkehrsstrassen) auftreten, bestimmt wird und die reale Fahrzeugflotte zu Grunde liegt. Der ausgewaehlte 2,3 km lange Tunnel der B 14 in Stuttgart-Heslach diente damit quasi als Grosslabor. Zur Bestimmung des aktuellen Fahrzeugkollektivs und des jeweiligen Verkehrsablaufs wurden ebenfalls umfangreiche Messungen und Erhebungen durchgefuehrt (z. B. Verkehrsstaerke, Verkehrszusammensetzung, Geschwindigkeit, Antriebsart, Hubraum, Leistung, Alter des Kfz). Die so ermittelten spezifischen Abgas-Emissionsfaktoren fuer Kraftfahrzeugstroeme koennen bei Wirkungsanalysen (z. B. Nutzen-Kosten-Untersuchungen von Strassenbauprojekten), bei Emissionskatastern, zur Kalibrierung von Ausbreitungsmodellen, zur Ableitung typischer Tagesganglinien einzelner Schadstoffe und auch zur Anpassung von Tunnellueftungen verwendet werden.
Ozone vertical column density in Dobson Units as derived from Sentinel-5P/TROPOMI observations. The stratospheric ozone layer protects the biosphere from harmful solar ultraviolet radiation. Ozone in troposphere can pose risks to the health of humans, animals, and vegetation. 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). Daily observations are binned onto a regular latitude-longitude grid. 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.
