Sentinel-5P TROPOMI – Sulfur dioxide (SO2), Level 3 – Global

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.

Kontinuierliche Ueberwachung der Schadstoffimmission der unteren Erdatmosphaere (bis 200 m Hoehe) mittels Fessel-Heissluftballon

Fuer Umweltschaeden haftet nach bestehendem Recht der Verursacher. Dieser ist insbesondere bei Luftverunreinigungen z.B. durch Verbrennung von Abfaellen bei Nacht in vielen Faellen nicht zu ermitteln, da wegen der geringen Sinkgeschwindigkeit staubfoermiger oder tropfenfoermiger Schadstoffe laengst alle Verbrennungsspuren o.ae. beseitigt sind, wenn am Erdboden die Immission erfolgt. Bei Ueberwachung der unteren 200 m der Atmosphaere koennen Emissionen aber sehr viel frueher bereits ermittelt werden. Bei radioaktiven Emissionen, z.B. bei Reaktorunfaellen, kann durch Messung in der unteren Atmosphaere die Konzentration schon so fruehzeitig erfasst werden, dass ggf. Raeumung der gefaehrdeten Gebiete noch moeglich ist.

Schwerpunktprogramm (SPP) 2115: Synergie von Polarimetrischen Radarbeobachtungen und Atmosphärenmodellierung (PROM) - Verschmelzung von Radarpolarimetrie und numerischer Atmosphärenmodellierung für ein verbessertes Verständnis von Wolken- und Niederschlagsprozessen; Polarimetric Radar Observations meet Atmospheric Modelling (PROM) - Fusion of Radar Polarimetry and Numerical Atmospheric ..., Untersuchung der Auswirkungen von Landnutzung und Landbedeckungsänderungen auf Aerosol-Wolken-Niederschlag Wechselwirkungen mittels polarimetrischer Radarretrieval-Messungen

Das Projekt ILACPR leistet einen Beitrag zum Ziel eines SPP durch die Nutzung der Radar-Polarimetrie zur quantitativen Prozess- und Modellbewertung, und wird neue Erkenntnisse zum Einfluss anthropogener Landnutzungs- und Landbedeckungsänderungen auf mikrophysikalische und makrophysikalische (dynamische) Wolkenmechanismen liefern. Erste numerische Modellierungsstudien zu einem sommerlichen Konvektionsereignis bei denen Aerosole und Landbedeckung großräumig gestört wurden deuten darauf hin, dass die Reaktion des Systems auf diese Antriebe bezüglich Oberflächenniederschläge gering ist. Jedoch unterscheiden sich die mikrophysikalischen/makrophysikalischen Wege, die als ein gepuffertes System auf Änderungen des Antriebs wirken. Polarimetrische Radarmessungen in Kombination mit solchen numerischen Modellrechnungen erlauben die Untersuchung von Puffermechanismen, die durch Wechselwirkungen zwischen Land, Aerosolen, Wolken und Niederschlagsprozessen entstehen. Die Polarimetrie ermöglicht es uns, die Entwicklung der mikrophysikalischen und makrophysikalischen Prozesse für simulierte und beobachtete Niederschlagswolken zu untersuchen. So sollten sich modifizierte Niederschlagserzeugungsprozesse durch sogenannte polarimetrische Fingerabdrücke identifizieren und quantifizieren lassen und uns somit die Validierung der modellierten Rückkopplungsprozesse zwischen der Oberflächenfluss-Partitionierung und der Aerosol-Wolken-Wechselwirkung ermöglichen. Die Terrestrial Systems Modeling Platform (TerrSysMP) wird genutzt werden, um den Einfluss von Landnutzungsänderungen auf die Aerosolverteilung und Land-Aerosol-Wolken-Niederschlag-Wechselwirkungen zu untersuchen. Weil TerrSysMP derzeit die Rückkopplung zwischen Landbedeckung, Atmosphärenchemie und Aerosolen ignoriert, wird das Atmosphärenmodell um ein chemisches Transportmodell (CTM) erweitert. Multiple Ensemble-Simulationen des Tagesgang werden mit unterschiedlichen meteorologischen Einstellungen werden mit TerrSysMP und TerrSyMP-CTM über dem nordwestlichen Teil Deutschlands, angrenzend an die Niederlande, Belgien, Luxemburg und Frankreich durchgeführt. Die gemeinsame Analyse von beobachteten und synthetischen polarimetrischen Fingerabdrücken für mikrophysikalische und makrophysikalische Prozesse, wie Verdunstung, Riming/Aggregationen, Aufwind-Abwind-Intensitäten wird auf Modellszenarien mit und ohne CTM basieren und es ermöglichen die gekoppelten Auswirkungen der anthropogenen Landnutzung und der Aerosole auf die Entwicklung von Niederschlag-erzeugenden Systemen besser zu verstehen.
