Boundary-Layer Structure and Air Quality in Urban Heat Islands and Sensitive Regions

Boundary layer structure and air quality in urban heat islands and in sensitive regions is measured with in-situ and vertical sounding systems recording near-surface values and vertical profiles of aerosol concentrations and meteorological parameters. An ultra-light aircraft with miniaturized instruments is available for boundary-layer air quality and flux measurements.

Near-surface in-situ and remote sensing techniques

In-situ meteorological parameters (wind, temperature, humidity, radiation)

Trace gas concentrations (CO₂, CH₄, N₂O, NO/NO₂, O₃, PM₁₀, CO)

Path-integrated concentrations of trace gases (DOAS, FTIR)

Scanning-imaging FTIR system (SIGIS)

Ground-based vertical profiling techniques
 

Further volume-exploring techniques

ultra-light aircraft for airborne in-situ measurements of meteorology, trace gases,
particles, fluxes

cell phone radiation attenuation (for precipitation measurements)
