Mission Summary: 

This was a science flight that was also the first Transit leg from Sao Tome island to Ascension Island.
Several objectives were accomplished on this flight:

  • Got a 4STAR “AeroNet-like” sky-scans below layers of dust plus smoke, then sampled the smoke layer in-situ. Also got vertically-resolved curtain from HSRL. The goal is to test AeroNet retrieval of column absorption/SSA and different methods of attributing column absorption to dust and carbonaceous aerosol.
  • Sampled smoke aerosol in northern end of study area to see if it is chemically/optically different than smoke to the south. Expect that aerosol in northern area more influenced by wet convection; southern area aerosol more influenced by dry convection.
  • Plume sampled along 5E on Aug 30, then re-sampled (per forward trajectories) on Aug 31 is expected to be just NE of ASI on 2 Sept. On approach to Ascension Island we re-sampled this aerosol to add to “Lagrangian”/aging study.
  • Included 10min leg in-cloud for HiGEAR to check for droplet shatter in CVI.
