Sentinel-5P TROPOMI – Aerosol Index (AI), Level 3 – Global

Aerosol Index (AI) as derived from TROPOMI observations. AI is an indicator for episodic aerosol plumes from dust outbreaks, volcanic ash, and biomass burning. 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.

Sentinel-5P TROPOMI - Aerosol Optical Depth (AOD), Level 3 - Global

Aerosol optical depth (AOD) as derived from TROPOMI observations. AOD describes the attenuation of the transmitted radiant power by the absence of aerosols. Attenuation can be caused by absorption and/or scattering. AOD is the primary parameter to evaluate the impact of aerosols on weather and climate. Daily AOD observations are binned onto a regular latitude-longitude grid.

Sentinel-5P TROPOMI - Aerosol Single-Scattering Albedo (ASSA), Level 3 - Global

Aerosol single-scattering albedo (ASSA) as derived from TROPOMI observations. ASSA is a measure of how much light is scattered by aerosols compared to how much is absorbed. It is important for understanding the impact of aerosols on climate and radiative forcing. ASSA is unitless; a value of unity implies that extinction is completely due to scattering; conversely, a single-scattering albedo of zero implies that extinction is completely due to absorption. Daily ASSA observations are binned onto a regular latitude-longitude grid.

Dynamisches Mosaik aus Sentinel-2 Daten NW

Das Dynamische Mosaik setzt sich aus aktuellen wolkenfreien Aufnahmen von Sentinel-2 Orthobildern zusammen. Die beiden baugleichen Sentinel-2 Satelliten des europäischen Erdbeobachtungsprogramms Copernicus liefern seit 2015 bzw. 2017 kontinuierlich Aufnahmen der Erdoberfläche. Der multispektrale optische Sensor verfügt über 13 Spektralkanäle im sichtbaren und infraroten Bereich. Dabei variiert die räumliche Auflösung von 10 m (Kanäle B02, B03, B04, B08) über 20 m (Kanäle B05, B06, B07, B08A, B11, B12) bis hin zu 60 m (Kanäle B01, B09, B10). Die Sentinel-2 Daten werden originär in den Prozessierungsleveln Level-1C (Top-Of-Atmosphere) und Level-2A (Bottom-Of-Atmosphere) angeboten und in Kachelgrößen von 100 x 100 km2 in UTM/WGS84 Projektion bereitgestellt. Für NRW liegen durch die hohe Wiederkehrrate der Satelliten alle 2-3 Tage flächendeckend aktuelle Aufnahmen vor. Da es sich bei dem Multispektralinstrument um ein passives System handelt, ist die Verwendbarkeit der Aufnahmen allerdings wetterabhängig. Die verfügbaren Orthobilder weisen unterschiedliche Wolkenbedeckungsgrade auf. Zur Ableitung des Dynamischen Mosaiks werden die aktuellen Sentinel-2 Bilder auf Wolkenbedeckung überprüft, so dass die wolkenfreien Bereiche selektiert werden können. Bereiche älterer Aufnahmen werden kontinuierlich durch aktuelle wolkenfreie Bilder ersetzt. Dabei werden die 4 Spektralbänder mit einer räumlichen Auflösung von 10 m (Rot, Grün, Blau, Nahes Infrarot) der Level-2A Daten berücksichtigt. Der Datensatz wird bei Vorliegen eines wolkenfreien Bereichs ab einer Größe von 100 zusammenhängenden 10 m x 10 m Pixeln fortgeschrieben, so dass stets die aktuellen wolkenfreien Aufnahmen im Mosaik enthalten sind. Das Dynamische Mosaik wird als Darstellungsdienst in den Ausprägungen RGB (Komposit aus den Spektralbändern B04-B03-B02) und CIR (Komposit aus den Spektralbändern B08-B04-B03) bereitgestellt. Darüber hinaus wird das Aufnahmedatum der jeweiligen Sentinel-2 Szene für jeden wolkenfreien Bereich zur Verfügung gestellt. Das Aufnahmedatum wird über die Sachdatenabfrage des Metadatenlayers angezeigt.
