About this Collection The purpose of this
annotated picture book and web links is to
illustrate some of the Web-based data resources
relevant to dust, smoke and haze Any use of data

Gobi Dust
Indochina Biomass Smoke

• April 7, 2002 was an active aerosol period over
  SE Asia
• A major Gobi dust cloud was streaking along the
  Mongolia-China border toward the Pacific
• The seasonal biomass burning over Indochina
  produced a thick, bluish, smoke plume

AERONET Sun Photometer Data Dalanzadgad
Brent Holben, brent_at_aeronet.gsfc.nasa.gov

• Sun photometer derived aerosol optical
  thickness indicates the passage of dusty air
  masses
• Dalanzadgad, Mongolia was in the path of several
  Dust storms in March and April 2002

• On March 16 for example, the aerosol optical
  thickness was about 2
• The wavelength-independence of AOT indicates that
  the vertical light extinction is due to dust
