DESCRIPTION:Exchange processes between the Earth&rsquo\;s surface and the a
 tmosphere are currently challenged by global change. Increased average sur
 face temperatures\, frequent droughts\, diversity loss\, or overloading th
 e environment with novel entities are just a few examples of this transiti
 on\, yet all have an impact on the Earth-atmosphere interface. One way to 
 study this interface in transition is by observing organic trace compounds
 . In the atmosphere\, organic compounds can be specific fingerprints of th
 eir sources\, signals for underlying processes\, indicators for reactions\
 , and tracers for airborne transport. Thus\, by identifying and quantifyin
 g organic trace compounds in the air\, we gain knowledge about natural and
  disturbed processes with impact on air quality\, weather and climate.\nDe
 dicating this colloquium to my tenure-track evaluation\, I will present an
  overview of the ongoing research activities of the Atmospheric Chemistry 
 group at the University of Bayreuth and highlight three examples. Firstly\
 , as the biosphere copiously emits volatile organic compounds (VOC) into t
 he air\, we explored their emission rates\, typical composition\, and vuln
 erability to environmental drivers such as increasing temperatures or drou
 ght. Secondly\, we traced particulate organic marker compounds to understa
 nd the origin and fate of ultrafine particles. Thirdly\, as rising surface
  ozone poses an increasing risk to remote ecosystems\, such as agricultura
 l vegetation or forests\, we explored the ozone formation potential with t
 he help of organic photochemical indicators.
