Elevated Smoke Plume over NY City, May 31, 2001
• Some smoke and haze plumes are above the surface layer, others are within
• Elevated layers can be inferred from the combination of surface and integral sensors

Elevated Asian Dust Layer over Washington DC
• The ‘Perfect Dust Storm’ in Gobi, April 7, 2001
• Transcontinental dust transport is well documented
• Goddard MP Lidar documents dust layer
• AERONET confirms by low (dust-like) the Angstrom exp.
