Studies on the microphysics and radiation properties of clouds

February to March 2011, 55 flight hours, based in Exeter, UK

Aircraft: FAAM- BAE - 146              ( )
          Max. altitude:  9200 m
          Length:          31.0 m
          Height:            8.6 m
          Wingspan:     26.3 m
          Range:    2400 km

Objective: Aircraft measurements to examine the links between
      aerosol particles and the development of drizzling stratus (water) clouds
      and mixed clouds (water and ice).
      The aircraft measurements are coordinated with
      ground measurements at different stations.

Forschungszentrum Jülich’s contribution to COALESC:
      Measurement of the size distribution of cloud particles (water droplets and ice)
      with the particle spectrometer NIXE-CAPS.
