Rain In Cumulus clouds over the Ocean
Puerto Rico Aerosol and Cloud Study
A field project on the East Peak at Puerto Rico, with the objective to
characterize cloud formation in the tropical trade wind region, using
the Aerodyne AMS in combination with a counterflow virtual impactor
(CVI) in order to study cloud droplet residual compostion.
Co-operation with:
IfT Leipzig (S. Mertes), UNAM Mexico (D. Baumgardner,
G. Raga), Univ. Puerto Rico (O. Mayol), Univ, Manchester (H. Coe, J.
Allan), Biogeo Dept. of MPI-C (G. Frank, U. Dusek)
Instruments:
Aerodyne Q-AMS, Grimm OPC 1.108, Grimm SMPS
