  We show that a consistent fit to observed secondary eclipse data for several
strongly irradiated transiting planets demands a temperature inversion
(stratosphere) at altitude. Such a thermal inversion significantly influences
the planet/star contrast ratios at the secondary eclipse,their wavelength
dependences, and, importantly, the day-night flux contrast during a planetary
orbit. The presence of the thermal inversion/stratosphere seems to roughly
correlate with the stellar flux at the planet. Such temperature inversions
might caused by an upper-atmosphere absorber whose exact nature is still
uncertain
