- The HALO research aircraft measures greenhouse gases over Canada.
- The CoMet 2.0 Arctic mission aims to analyse natural and manmade methane sources more closely and to test new climate monitoring tools.
- Focus: Space, Earth observation
Coal mining, oil and gas production, landfill and agriculture are all anthropogenic sources of the greenhouse gas methane, which is the second most important contributor to climate change after carbon dioxide. A methane molecule has an up to 86 times stronger climate impact than carbon dioxide. This is compounded by Earth’s large wetlands and thawing permafrost, which are among the most important, albeit least understood, natural sources and sinks in the global methane and carbon dioxide budget. In August and September 2022, the German research aircraft HALO will fly over Canada to investigate more precisely how much these individual sources emit greenhouse gases and how more clearer distinctions can be drawn between natural and manmade sources in analysis. As part of the CoMet 2.0 Arctic (Carbon dioxide and methane mission for HALO) mission, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is conducting research alongside partners from the Max Planck Institute for Biogeochemistry in Jena, the University of Bremen and Ludwig Maximilian University (LMU) in Munich to record climate gas emissions more precisely and extensively in future, with a view to making climate forecasting more accurate.
