An extended method based on a modified water cloud model that combines with ASAR
and the TM data to estimate aboveground biomass and describes an application of this
methodology in a mixed vegetation area of the Wutumeiren Prairie in China.

Dense smog settled over
the North China Plain on
February 20, 2011. The
featureless gray-brown
haze is so thick that the
ground is not visible in
parts of this photo-like
image taken at 11:35
a.m. by the Moderate
Resolution Imaging
Spectroradiometer
(MODIS) on NASA’s Terra
satellite. At that time, a
weather station at Beijing’s airport reported visibility
of 1.9 miles (3.1 kilometers). Visibility dropped as low
as 1.1 miles (1.8 km) later in the afternoon.
Smog frequently builds up in eastern China during the
winter when weather conditions trap pollutants over
the plain. Haze had been reported over Beijing for
much of the previous week.
It is not possible to tell from this view exactly what
pollutants made up the haze on February 20, but it
probably contains mostly soot or black carbon and
possibly some ground-level ozone. Soot is released
from burning fossil fuels (particularly diesel and coal),
wood, and other biofuels. These same processes also
release chemicals that combine in sunlight to form
ozone: methane, nitrogen oxides, volatile organic
compounds, and carbon monoxide. In China, coal is an
important fuel burned in home heating and cooking
and energy production.
