| Proposal Synopsis: | SUMMARY WORK STATEMENT Augment existing or establish new aerosol sampling sites for continuous size and time resolved aerosol composition. Pair sites in planetary boundary layer (PBL) and lower free troposphere when possible (3 sites). Collect aerosols at 7 land and 1 ship-based sites using continuously rotating DRUM samplers, 4 hr resolution (2 weeks per sample), in 8 size modes, and at 4 sites, in 3 size modes for 6 weeks , spring 2001. There will be a 4 weeks intensive, summer 2001, Cheju and Japan. Analyze all for mass and optical parameters, and selected (roughly 25%) samples for major/minor constituents (PIXE/PESA), trace elements by synchrotron-XRF, organics by LDITOF-MS spectroscopy and H surrogate mass. Collect aerosol on IMPROVE equivalent IAS and IMPROVE samplers, with filters for quality assurance purposes, PM2.5, and analyze for mass, major and trace elements, soot, anions/cations, organics by TOR and GC/MS. Collect aerosol by Hi-Vol filters at Cheju, Korea (Kosan and Cheju high site), and potentially one other site. Analyze by size for S and O isotopic analyses. Evaluate aerosol sources and sinks, transport, transformations (esp. modification of dust by anthropogenic species), trace elements associations to known industry, modification by oceanic transport, using trajectory analysis, statistical analysis (PCA) and remote sensing (satellite) data. Sites: China: Yu Lin, Beijing, Hefei (also coop. UC Pac Rim with Qing Dao); Taiwan: Mt. Bamboo, (also coop UC Pac Rim); possible Lu-Li Mountain (4 km) Korea: Cheju (Kosan); Cheju high (1.1 km) Japan: Noto Penn/Kanazawa ; Mt. Norikura (2.2 km/2.7 km); Uji (Kyoto) Supporting but not ACE-Asia: US: (coop UC Pac Rim with Mauna Loa Observatory (3.1 km), Crater Lake NP .lt.a href=http://(2.2km)). .gt.(2.2km)). .lt./a.gt..lt.br.gt. |
