Stratosphere
Standard Atmosphere
q  The reasons for the inversion in
the stratosphere is due to the ozone
absorption of ultraviolet solar
energy.
q  Although maximum ozone
concentration occurs at 25km, the
lower air density at 50km allows
solar energy to heat up temperature
there at a much greater degree.
q  Also, much solar energy is
absorbed in the upper stratosphere
and can not reach the level of
ozone maximum.
lapse rate = 6.5 C/km
