Presentation Transcript

  1. Autonomous measurements and global modeling of mineral aerosols Amato Evan Scripps Institution of Oceanography, University of California San Diego, USA

  2. Key Questions What are the spatial, temporal, and microphysical characteristics of dust over California, and what are the primary source regions for these mineral aerosols? Does dust emission from remote sources change on interannual and longer time scales, and what is the effect on rainfall over California?

  3. Autonomous Measurements MPL OPC CARAGA

  4. Deposition, surface conc. & size Autonomous California Dust-Monitoring Network Deposition, surface conc. & size, vertical structure 20 sites w/CARAGA & particle counter 4 sites would also include MPL Possible to keep cost in neighborhood of $1M for equipment

  5. Long-Term Variability:Over-Land Dust Detection with AVHRR?

  6. Long-Term Variability:Sub to decadal scale records Mono Lake Tufa Owens Lake Lacustrine Stromatolites

  7. Long-Term Variability:20th Century numerical experiments Modeling dust in a GCM… …is not so easy to do!
