Light spectra measured inside the AIDA aerosol and cloud simulation chamber M. Vallon, L. Gao, F. Jiang, B. Krumm, J. Nadolny, J. Song, T. Leisner, and H. Saathoff

Short summary
A LED-based light source has been constructed for the AIDA simulation chamber at the Karlsruhe Institute of Technology. It allows aerosol formation and ageing studies under atmospherically relevant illumination intensities and spectral characteristics at temperatures from –90 °C to 30 °C with the possibility of changing the photon flux and irradiation spectrum at any point. The first results of photolysis experiments with 2,3-pentanedione, iron oxalate and a brown carbon component are shown.
