Barbados Workshop October 24th/25th, 2011

On the 24th and 25th of October, a Barbados Workshop took place in Hamburg. Presentations showed the progress and data analysis made by the various working groups involved in the Barbados initiative. Special interest was on first results from the Opens external link in current windowCARRIBA campaigns. Furthermore, extensive discussions dealt with future plans for the project and collaboration between the working groups.

Presentations

Louise Nuijens, Holger Siebert, Birgit Wehner and Heike Wex gave overview talks:

 

  • Louise Nuijens (MPI): Status of the site at Ragged Point, physical variables of Cloud Radar, Micro Rain Radar and Raman Lidar, investigation of the cloud-rain-aerosol relation with long-term statistics, first results; download Initiates file downloadhere.
  • Holger Siebert and Birgit Wehner (IfT): ACTOS flights during CARRIBA 2010/2011 (in situ, heli-borne), boundary layer structure, dynamics at the cloud edge, aerosol and droplet spectra, new particle formation; download Initiates file downloadhere.
  • Heike Wex (IfT): ground-based measurements of aerosols during CARRIBA 2010/2011 (in situ), airmass origin (trajectories), chemical composition, number size distributions, hygroscopicity; download Initiates file downloadhere.
