Photograph of the South Asian Brown haze over
the Nepalese town of Phaplu (bottom panel), taken
on March 25, 2001,
approximately 30 km south of Mt. Everest (top panel), from a flight altitude
of about 3 km. Both photographs were taken
from the same location, one viewing north (top) and the other south (bottom).
During the dry season from January to April,
the brown sky seen over
anthropogenic haze thousands of kilometers south and south eastwards, and
spread it over most of the tropical Indian Ocean
between 25² N to about 5² S (Ramanathan, V., P. J. Crutzen,
J. T. Kiehl and D. Rosenfeld, 2001: Aerosols,
Climate and
The Hydrological Cycle. Science, 294, 2119-2124).
