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 Nepal is typical of many areas in South Asia . The dry north east monsoonal winds carry this
anthropogenic haze thousands of kilometers south and south eastwards, and spread it over most of the tropical Indian Ocean
between 25 N to about 5 S (Ramanathan, V., P. J. Crutzen, J. T. Kiehl and D. Rosenfeld, 2001: Aerosols, Climate and
The Hydrological Cycle. Science, 294, 2119-2124).
