Institut für Physik der Atmosphäre
The Institute of Atmospheric Physics investigates the physics and chemistry of the global atmosphere from the Earth's surface up to the upper boundary of the middle atmosphere at about 120 km height. As an institute of the German Aerospace Center (DLR) we answer questions associated with atmospheric processes and with relevance to the research programmes "Aeronautics, Space, and Transportation" and "Energy" of the Helmholtz Association (HGF).
DLR - NASA flight tests on alternative fuels
Over the next 15 years, global air traffic is expected to double. Sustainable alternative aviation fuels can play an important role in the environmentally and climate-friendly development of air traffic. Since 2014, the German Aerospace Center (DLR) and the US Aerospace Agency (NASA) have been jointly testing the emissions and properties of contrails of alternative fuels during flight and ground tests. In 2018, joint research flights were held in Germany for the first time. For this purpose, the DLR research aircraft A320 ATRA (Advanced Technology Research Aircraft) and the NASA research aircraft DC-8 DLR research aircraft were stationed at the Ramstein Air Base for three weeks and carried out eight test flights in German airspace.
HALO measures emissions of Asian megacities
Emissions of large cities and urban agglomerations can spread far beyond the borders of the metropolises in certain weather conditions. Particles and gaseous pollutants are often carried by the wind for more than 1,000 kilometers. In March and April 2018, the DLR Institute of Atmospheric Physics (IPA) carried out extensive measurements of the composition and propagation of emissions from Asian megacities using the HALO research aircraft.
Comparisons of climate simulations in the target
Under the auspices of the World Climate Research Program (WCRP), hundreds of climate researchers in modeling centers around the world are working to share, compare and analyze the latest results of global climate models. Within the CMIP (Coupled Model Intercomparison Project) project, in which the DLR Institute of Atmospheric Physics is participating, simulations of the research community provide important data for the next five to ten years.
IPA contributes to the Coupled Model Intercomparison Project
As part of the Coupled Model Intercomparison Project (CMIP) organized under the auspices of the World Climate Research Programme’s (WCRP) Working Group on Coupled Modelling (WGCM) many hundreds of climate researchers, working with modeling centres around the world, will share, compare and analyze the latest outcomes of global climate models. These model products will fuel climate research for the next 5 to 10 years, while its careful analysis will form the basis for future climate assessments and negotiations. The sixth phase of CMIP (CMIP6) is now underway with the WCRP Grand Science Challenges as its scientific backdrop. The DLR Institute of Atmospheric Physics (IPA) will contribute to CMIP6 by running the ESMValTool routinely on model output submitted to the CMIP archive for a more systematic, open and rapid performance assessment of the large and diverse number of models. The Institute of Atmospheric Physics will also participate in CMIP6 by contributing simulations with the EMAC model.
Biofuels reduce soot emissions from aircraft
7 April 2017
A fuel blend with 50 percent biofuel reduces soot particle emissions of the aircraft by 50 to 70 percent compared to conventional fuel, according to a study published in the scientific journal Nature. The findings are based on an international flight experiment between NASA, the DLR Institute of Atmospheric Physics and the National Research Council (NRC) of Canada.
