Research Foci

The Research Area "Atmospheric Variability and Trends" comprises the following Research Foci:

TCCON Network

High-precision column measurements of Kyoto gases (CO2, CH4, N2O) within the TCCON network for inverse modeling of sources and sinks.


Validation of atmospheric chemistry satellite missions, meteorological satellites, and greenhouse gas satellites.

Lidar Measurements

Development of ground-based remote sounding methods and synergetic use in combination with satellite data.


Long-term measurements and trend studies within international networks and for monitoring of international protocols (Montreal Protocol, Kyoto Protocol) for emission reductions.

Vertical exchange

Investigation of vertical exchange and long-range transport of trace compounds within troposphere / lower stratosphere.
