  22. Desert Dust: update- V3 TOMS data- July 2004 comparisons- Case Study?

  23. Time series, W.Sahara, July 2003

  24. TOMS V3 Aerosol Index, July 2004:correlation with MISR and conversion to AOD_0.55 TOMS AOD_0.55 TOMS AI MISR AOD_0.55

  25. TOMS V3verses V2: July 2003

  26. Model-GERB OLR Model-GERB(ARCH) OLR July 2004: Model minus GERB/ARCH OLR diff:1200 UT TOMS AOD_0.55 Model-GERB(ARCH) OLRc

  27. Model (Type I) GERB (ARCH) July 2004: Clear-sky OLRClear-sky OLR difference Model (Type I) minus GERB (ARCH)

  28. Possible Case Studies • July 2004 experiment • Desert Dust (e.g. 21 July 2004) • Cirrus Outflow (e.g. 1 July 2003) • Convection over land • Stratocumulus • Sahara albedo: further modifications?
