Radiative Forcing

20 w/m2
15 w/m2
radiative forcing of the aerosols = 15-20 = -5 w/m2
q Radiative forcing is a measure of the influence a factor has in
altering the balance of incoming and outgoing energy in the
Earth-atmosphere system, and is an index of the importance of
the factor as a potential climate change mechanism. It is
expressed in Watts per square metre (Wm-2).
