Institute of Meteorology and Climate Research - Atmospheric Trace Gases and Remote Sensing

The Institute of Meteorology and Climate Research (IMK) - Atmospheric Trace Gases and Remote Sensing (ASF) investigates dynamic, microphysical and chemical processes in the Earth’s atmosphere, with the goal to understand, quantify and predict its natural variability and long-term changes.

Accurate measurements of atmospheric trace gases from various observational platforms (ground-based stations, air craft, balloons, satellites) provide the data that are required for the modelling of atmospheric processes.

Particular focus of the activities of IMK-ASF is to investigate the complex links and feedbacks between climate change, dynamics and transport, and atmospheric chemistry.


POLSTRACC campaign: indication of strong ozone depletion over the Arctic

So far, the Arctic stratosphere has been unusually cold this winter setting the stage for strong ozone depletion over the coming few weeks. One important role are vertically expanded stratospheric clouds that have reached unusually low into the lower stratosphere and covered a broad area over the Arctic region. First signs of activation of chlorine and redistribution of reactive nitrogen and have been observed.

Information on the campaign

Ozon und Klima Forschungsflugzeug HALO
Ozone and Climate: With the HALO research aircraft to the North Pole

The KIT-coordinated measurement campaign POLSTRACC (Polar Stratosphere in a Changing Climate) studies impacts of climate change on the Arctic ozone layer and processes in the tropopause region below.
Currently, first test flights are carried out from the DLR base at Oberpfaffenhofen near Munich. Between January and March 2016, the “Arena Arctica” in Kiruna, Sweden, near the polar circle, will form the base for 10 to 15 research flights across the polar sea towards Greenland and the North Pole.

Forschungsflugzeug HALO
Durch den Monsun: Flugzeugmission zu Auswirkungen auf Luftqualität und Klimawandel

Die Selbstreinigungskraft der Atmosphäre steht im Fokus der 30-tägigen Halo Kampagne OMO (kurz für Oxidation Mechanism Observations, „Beobachtung von Mechanismen der Oxidation“), die am 21. Juli von Zypern aus gestartet ist. Zunächst stehen Analysen über der arabischen Halbinsel und dem arabischen Meer auf dem Programm. Dann wechseln Flugzeug, Crew und Team auf die Malediven, um von dort aus die Atmosphäre über dem indischen Ozean und dem Golf von Bengalen zu analysieren. Anschließend geht es nochmals zwei Wochen nach Zypern.

Partitioning and budget of inorganic and organic chlorine species observed by MIPAS-B and TELIS in the Arctic in March 2011

The MIPAS-B and TELIS balloon measurements obtained in northern Sweden on 31 March 2011 inside the stratospheric polar vortex have provided vertical profiles of inorganic and organic chlorine species as well as diurnal variations of ClO around sunrise over the whole altitude range in which chlorine has been undergoing activation and deactivation. The complete inorganic and organic chlorine partitioning and budget (representative for the late winter Arctic stratosphere) has been derived by combining MIPAS-B and TELIS simultaneously observed molecules. A total chlorine amount of 3.41 ± 0.30 ppbv is inferred from the measurements (between 25 and 36 km). This value is in line with previous stratospheric observations carried out outside the tropics confirming the slightly decreasing chlorine amount in the stratosphere

High latitude volcanic aerosol impact on incoming solar radiation
New in situ aerosol data from the CARIBIC Obersvatorium in combination with newly evaluated CALIPSO satellite data show a significant impact of northern hemisphere high latitute volcanic eruptions on incoming solar radiation. The study has been published in Nature Communications
