Aircraft Noise: The major sources, modelling capabilities, and reduction possibilities

Lothar Bertsch
In October 2014, the first ”Joint DLR & TU Delft Aviation Noise Workshop” was organized. This publication is the executive summary of this event. Overall, 38 invited participants from industry, academia, and research institutions have discussed the specific topic of this first 3 day workshop, i.e ”Aircraft Noise Reduction at the Source”. Four specific tasks were formulated in order to address the problem, i.e. (1) identification of main aircraft noise sources on-board of a given...

Land Cover DE - Sentinel-2 - Germany, 2015

Matthias Weigand & Michael Wurm
This land cover classfication of Germany was created using Sentinel-2 imagery from the years 2015 to 2017 and LUCAS 2015 in-situ reference data (https://ec.europa.eu/eurostat/web/lucas). It contains seven land cover types: (1) artificial land, (2) open soil, (3) high seasonal vegetation, (4) high perennial vegetation, (5) low seasonal vegetation, (6) low perennial vegetation and (7) water with a spatial resolution of 10m x 10m.

TanDEM-X - PolarDEM - Antarctica, 90m

Birgit Wessel & Martin Huber
The TanDEM-X PolarDEM is a project developed by the German Remote Sensing Data Center (DFD) at the German Aerospace Center (DLR) within the activities of the TanDEM-X mission. It is a framework for the provision of derivatives of the global Digital Elevation Model (DEM) of the TanDEM-X mission for Polar Regions. The TanDEM-X PolarDEM 90m of Antarctica is a gap-free and edited version of the TanDEM-X 90m digital elevation model (DEM). The TanDEM-X PolarDEM 90m...

Noise Prediction within Conceptual Aircraft Design

Lothar Bertsch
Motivation for the presented activities is the integration of noise as an additional objective in conceptual aircraft design. Therefore, the Parametric Aircraft Noise Analysis Module (PANAM) is developed to account for individual noise sources depending on their geometry and operating conditions. Each major noise source is modeled with an individual semi-empirical noise source model. These models capture the major relevant correlations, can still be executed on a standard desktop PC, and provide comprehensive simulation results....

FireBIRD sieht Waldbrände mit Adleraugen

Dieter Oertel, Thomas Terzibaschian & Winfried Halle
Vegetationsfeuer werden aus dem Orbit erfasst und bewertet, um ihre Rolle für das Klima zu verstehen und um diese Feuer effektiver zu bekämpfen. Die FireBiRD-Mission des DLR ist aber auch deshalb interessant, weil man von ihr eine Menge über die Welt der Satelliten lernen kann, ohne die in der heutigen Gesellschaft vieles nicht mehr funktionieren würde.

fCover - Sentinel-2 - Netherlands, 2016

David Marshall
The Sentinel-2 fractional vegetation cover (fCover) product for the Netherlands was produced as part of the NextGEOSS project at the German Aerospace Center (DLR). The goal is to derive abundance maps from atmospherically corrected Sentinel-2 multispectral images for: photosynthetically active vegetation (PV); and for combined non-photosynthetically active vegetation (NPV) and bare soil (BS). The fCover product for the Netherlands has been generated by processing 10 cloud-free Sentinel-2 tiles which covered the country on 8 September...

SLED (Silent Leading Edge Devices) - Abschlussbericht zum Flugzeugentwurf und der Systemanalyse

Lothar Bertsch
Der vorliegende Bericht gibt eine Übersicht über die Aktivitäten der Abteilung Hubschrauber des Institutes für Aerodynamik und Strömungstechnik (AS-HEL) und der Abteilung Systemanalyse Lufttransport des Institutes für Lufttransportsysteme (LY-SLT) im Rahmen des Projektes Silent Leading Edge Devices (SLED). Der Grundgedanke des SLED-Projektes liegt darin, dass Fluglärm durch den an- und abiegenden Luftverkehr im Nahbereich von Flughäfen ein immer stärker in den Fokus rückender Faktor bei der Auslegung und dem Betrieb von kommerziellen Luftfahrzeugen wird. Die...

Data supplement to: Fiehn et al (2020): Estimating CH4, CO2, and CO emissions from coal mining and industrial activities in the Upper Silesian Coal Basin using an aircraft-based mass balance approach

Alina Fiehn, Julian Kostinek, Maximillian Ecki, Theresa Klausner, Michał Gałkowski, Jinxuan Chen, Christoph Gerbig, Thomas Röckmann, Hossein Maazallahi, Martina Schmidt, Piotr Korbeń, Jarosław Nȩcki, Paweł Jagoda, Norman Wildmann, Christian Mallaun, Rostyslav Bun, Anna-Leah Nicki, Patrick Jöckel, Andreas Fix & Anke Rolger
Supplementary data with CO2 and CH4 observations from in situ and airplane platforms during a campaign over the Upper Silesian Coal Basin (USCB), Poland, in summer 2018. The campaign is described in the paper: Fiehn, A., Kostinek, J., Eckl, M., Klausner, T., Gałkowski, M., Chen, J., Gerbig, C., Röckmann, T., Maazallahi, H., Schmidt, M., Korbeń, P., Nȩcki, J., Jagoda, P., Wildmann, N., Mallaun, C., Bun, R., Nickl, A.-L., Jöckel, P., Fix, A., and Roiger, A.:...
