Today we visited the Concorde center near Grantley Adams International Airport where a group from IfT Leipzig is doing measurements with ACTOS, their platform of instrumentation, that is hanging with a rope 150 m below a helicopter. ACTOS measures many things, among which high resolution humidity and wind components, CCN spectra, cloud liquid water, and more. In between ACTOS and the helicopter flies Helios, that looks like an atomic bomb, but just measures spectral (ir)radiances above cloud tops. You can find the link to their blog on the right hand side, with many elaborate descriptions of their findings. They perform like a real good team! We also took a short helicopter flight over to our site, where I could take a picture.
