TL;DR: In this paper, the ozone depletion on carbon soot aerosol was investigated in the temperature range 238-330 K for reaction times up to 72h: 200μg m−3 ozone in dry synthetic air is depleted with an initial reaction probability γ=1.2×10−6 at 296-K. The reaction probability decreases with a characteristic time τ of about 12h (1/τ=k3=(2.3±0.6)× 10−5 s−1) due to surface passivation.

TL;DR: In this paper, the authors investigated the ice nucleation activities of five different Pseudomonas syringae and Erwinia herbicola bacterial species in the temperature range between −5 and −15°C and found that only a minor fraction of the cells acted as heterogeneous ice nuclei either in the condensation or immersion mode.

TL;DR: In this paper, the effect of organic carbon (OC) content on the ice nucleation properties of soot aerosol particles was investigated in the AIDA (Aerosol Interactions and Dynamics in the Atmosphere) chamber.

TL;DR: In this paper, the authors test if glassy aerosol distributions with a range of chemical compositions heterogeneously nucleate ice under tropical tropopause layer (TTL) conditions.

TL;DR: The AquaVIT-1 intercomparison of atmospheric water vapor measurement techniques was conducted at the aerosol and cloud simulation chamber AIDA (Aerosol Interaction and Dynamics in the Atmosphere) at the Karlsruhe Institute of Technology, Germany, in October 2007.
