OK, so you've got a three-word summary of some
hyperbole with Dumbo, the Flying Elephant.
How are you going to deal with the real
scientific constraints on the physics of combining real
measurement technologies and "mashing stuff together"?

You need to remember that imaging instruments integrate
radiances with spectral responses and Point Spread Function
weighted averages over the FOV of whatever the instrument
was looking at - and that's just the instantaneous (L1 measurement).
If you do orthorectification, you've got variations in the uncertainties
across the image where the parts of the image where you've
increased the resolving power (by putting interpolated points
closer together) and have also increased the noise from the
orthorectification process that acts as a noise multiplier.

Next, you've got stuff like cloud identification (and rejection or
acceptance) - which depends on spectral response, solar illumination
(during the day) and temperature and cloud property stuff during
the night - and finally, you've got temporal interpolation (not just
creating an average through emission driven by solar illumination
during the day and IR cooling at night.  Where (the hel)l is
the physics that deals with this stuff?  If you do get some
statistical stuff, why should anyone believe it contributes to
our understanding of climate change?

I won't vote, but you can think of this as my input to your
scientific conscience.
