good stuff, Note it is Volume 28, 28 volumes, a lot of stuff to wade
through.
but on that page page 8,328 or so figure 1 is a nice diagram that
illustrates the process people are trying to bound. But to get to this,
they had to make a huge number of assumptions, which should be reflected
in the uncertianty of the number, notice -184 +-9 LW cooling for +_ 5%.
But 5% accuracy is nominal in measuring instruments, 3% in better
instruments. 1% is quite difficult to get to.
So how can an entire planet, with its natural processes, clouds, layers,
be measured accuractly, and over time, to not very more than +_5% ?
I traced some of this back to how temerature were used to get high
accuracy, and what they used was daily average temperatures, so the
temperature extremes were washed out. the varance was not brought
forward. Then they average the daily average temperatures again and
spread out that number over a larger area, so more variance is wash out.
So you can arrive at a precision number 59.04 degrees F, which you think
represents a yearly average over the state of Maine, however that number
is swollowed up by the large varances, that were 'averaged out', so in
Maine it is difficult for one to measure 59.04 at any time, any place,
it is usally some other number.
for example, say the input is 5 to 105 and has an even probability of
the range between the two, the average is 55.00 , but the measured will
almost never be 55.00.
The point is that many processes with large variances cannot be
accurately described using typical mathematics (remember the book "Black
Swan" by Taleb?), the variances of the underlying data need to be
included in the calculations, and brought forth.
in that paper you linked to, they have errors in their data, (in the
error bounds) one is in Table 3, incomeing solar F at 340.2 +_ 0.1 or
0.029 % another paper states it is 1370 W/m^2 +- 3.4% due to
eccentricity of Earths orbit. (you can ignore units conversion)
How can the sun radiation only vary by 0.029% ? How can we measure that
accuractly ? What bands, what filters, what detectors were used, and
how were they calibrated ? My point is the extreme presision they
arrive at is an artifact of averaging.
From that paper: page 8332, second paragraph
"This is achieved by invoking two common (and nec-
essary) assumptions concerning the uncertainties in the
component fluxes: that they are random and Gaussian.
While it is difficult to justify either of these assumptions,
they are required in the absence of definitive bias or error
distribution information."
which means they punted, and just assumed Gaussian random
distrubutions, because the computers are already setup for that canned
function. (it is not "necessary" as they state)
they made the already averaged data fit their math tools, throwing
out variance and real distributions.
page 8332 has other statements on it that should raise concern;
"A larger value of ki^2 is indicative of larger
than anticipated biases in one or more of the component
fluxes. Another simple (but valuable) metric of the
success of the optimization is a direct comparison of the
magnitudes of the adjustments made to each component
flux against their estimated uncertainties. Energy budget
residuals, computed as the sum of the adjustments to the
component fluxes, that exceed associated error bounds
are indicative of areas where balance could not be ad-
equately achieved."
"One of the principal advantages of this approach lies
in the fact that it can be scaled to arbitrarily complex
problems involving any number of fluxes and con-
straints. In particular, it can be used to establish an ex-
plicit link between the energy budget and water cycle
through the connection between latent heating, evapo-
ration, and precipitation. In this way, disparate obser-
vational datasets that are seldom considered together,
such as radiative fluxes and surface runoff, can be cou-
pled to their mutual benefit through their relationships
to precipitation and evaporation in energy and water
budget closure equations. "
following is a news article that highlights part of the problem, (it
misses the fact that daily temperature varance were washed out).
https://wattsupwiththat.com/2015/02/01/uncertainty-ranges-error-bars-and-cis/
one can draw many lines through and be within all the error bars, and
they are viable answers too.
