Wouldn't you just know it, that the first of the Venus EXPRESS 6
composite images as having been officially processed for delivering to
us village idiots the most eye-candy and otherwise contributed for our
investigative pleasure, whereas thus far such images are showing a
semi-thermal gradient ratio of .075 to 0.5, as representing a 6.67:1
ratio from the fully solar illuminated side to significant portions of
the nighttime atmospheric season as being considerably cooler.
Actually, some of the coolest zones are not worth 0.05, thus we're
talking 10:1 as being the maximum differential, that which doesn't
surprise myself one bit.

It's the transitions from daytime to tighttime and of the polar vortex
patterns that are the most reveiling.

In addition to whatever's of an unavoidably extra toasty atmospheric
season of daytime, as false colour depicted and as otherwise expected
it seems the much cooler nighttime season is covering a considerably
greater percentage of that atmospheric environment by something near
15%, with a great deal of thermal energy extraction taking place at the
poles. Since these images are a composite of UV through near-IR is why
there's no specific thermal gradient involved, other than the afforded
by the observed differential that's as great as 10:1 as based upon the
graphic scale included with each image. The actual thermal range of
daytime/nighttime differentials will likely soon follow unless FW
Taylor desides otherwise.

"The images (taken at 5 microns) were obtained at six different time
slots and different distances from Venus (top left: 12 April, from 210
000 kilometres; top cent 13 April, from 280 000 kilometres; top
right: 14 April, from 315 000 kilometres; bottom left:16 April, from
315 000 kilometres; bottom cent 17 April, from 270 000 kilometres;
bottom right: 19 April, from 190 000 kilometres), while the spacecraft
moved along a long ellipse around the planet. The separate images can
be downloaded here [ COB_01_geo.TIF, COB_02_geo.TIF, COB_03_geo.TIF,
COB_04_geo.TIF, COB_05_geo.TIF, COB_06_geo.TIF]."

BTW; there is also an interesting little item of less than one degree
that's seemingly operating above the cloud layer of that planet, that's
depicted as somehow much cooler than the surrounding atmosphere, being
too large for any artificial satellite that we could possibly have
accomplished. It's existing as though operating just above the equator
and near the 20 degree mark. Because it's within 6 out of 6 images, as
such I doubt that it's of an imaging glitch.
