Missing entirely from Pielke's post is the fact that 2000 was before the major
diurnal drift correction.
[Response: To clarify, the «personal communication» from RSS to S+C concerned a sign error in how
the diurnal drift correction had been applied in the S+C 2LT product.
Not exact matches
(Note that we were first to discover the
diurnal drift problem back in the 1990s and initiated various
corrections for it through the years.)
AQUA has a self - correcting propulsion system, so the UAH annual cycle, and the cyclic component of UAH - RSS divergence, can not be the result of differing methods of
correction for
diurnal drift resulting from orbital decay.
In other words, RSS has to make a
correction for
diurnal drift, while UAH does not.
