The stratosphere in global change

IEK-7 Aktivitäten



IEK-7 conducts research on the chemistry, dynamics and microphysics of the stratosphere and the tropopause region, and on the role these atmospheric layers play in the climate system.

For this purpose, aircraft and balloons are used for experiments intended to clarify processes, primarily on a local and regional scale. With the analysis and use of satellite data, these studies are expanded to include global and climatological scales. The evaluation of the measured data is closely interlinked with model calculations.

Announcements and Events

a

HEMERA campaign concluded

Precise measurements of the atmosphere are indispensable for predictions of climate change and its consequences. A group of researchers from the Helmholtz Association in Jülich and Karlsruhe has therefore been carrying out unique experiments in August in Kiruna in northern Sweden. Two large balloon gondolas were prepared and launched as part of the EU Horizon 2020 HEMERA research infrastructure (https://www.hemera-h2020.eu/).

FOCUS

Research

IEK-7 studies chemical, microphysical and dynamic processes in the atmosphere and the role they play in climate change. The institute focuses on the tropopause region (5 to 15 km), because this is where changes in greenhouse gases, aerosols and clouds have a particularly strong effect on the radiative forcing of the atmosphere.

Methods and Data

In this section we present methodical pillars of IEK-7 research as well as data sets.

Results

The results of our research are regularly published in the scientific literature. We also make key contributions to international assessments carried out by institutions such as WMO, IPCC and SPARC, which form the basis of decisions taken by policy makers in the field of atmospheric research and climate research. You can find information on past and present IEK-7 publications.
