• Vertical data are crucial for PM transport
• MPL LIDAR data on July 7 show smoke descending
  from 3 km to the surface

• 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
