Introduction to the AIDA facility

The AIDA facility is suited for investigating chemical kinetics, aerosol chemistry, aerosol physics, and cloud microphysics in a wide range of atmospheric pressure (1 to 1000 hPa), temperature (60 °C to -90 °C), and relative humidity (from almost 0 % to 100 %). During cloud experiments, transient water and ice supersaturations are achieved for time periods from minutes up to about 1 hour with peak values of more than 100%.

What makes AIDA a unique facility for air pollution, weather, and climate research is the combination of its size, temperature range, and comprehensive trace gas, aerosol, and cloud instrumentation.
