The image on the left represents absorbing
aerosol particles (airborne microscopic
dust/smoke) blowing out to sea from North Africa. The image on
the right represents the cloud cover as seen by OMI for the
same day and time as the aerosol image. For more details regarding
the clouds, see our reflectivity
page.
The data from TOMS record have been used
increasingly to understand the behavior
of this material within the atmosphere. The TOMS is the first
instrument to allow observation of aerosols as the particles
cross the land/sea boundary. Using these data it is possible
to observe a wide range of phenomena such as desert dust storms,
forest fires and biomass burning.

November 2000 Special Note:
After four years in orbit, the Earth Probe TOMS instrument is
experiencing some wavelength-dependent calibration drift which
is affecting the aerosol index calculation (whereas the effect
on total ozone calculation is very small). The problem is being
looked into which could lead to a re-computation of recent aerosol
index values and re-generation of recent aerosol index images
for Earth Probe TOMS.
