Title: Sunrise, Earth Limb 
 
Description: 
 
This sunrise scene (5.5S, 29.5E) was taken early in the morning, when the 
sun  was still below the horizon and not yet illuminating the dark band of 
low  level clouds on the Earth limb.  Ranging from 13 to 18 km. above these 
low  level clouds is a brown layer at the tropopause, an atmospheric 
temperature  inversion which isolates the troposphere from the stratosphere 
and  effectively concentrates particulates from both above and below this 
level.
