Improvements in methods and equipment, processes of maintenance and calibration as well as a vastly better understanding of measurement methods have reduced the measurement
errors by an order of magnitude over those years.
Not exact matches
My
error bars here are huge, but it seems to be the same
order of magnitude that Stein was asked to spend
by the states to get the recount effort started.
I checked the worst
error that could be caused
by persistent rounding and it was many
orders of magnitude smaller than the discrepancy I was seeing.
Are you going to man up and admit your
error, as you demanded
of Victor, or are you not just wrong
by over an
order of magnitude in capacity and maybe, I du n no, two or three
orders of magnitude in cost, but also a hypocrite?
(The «I think» was because I was hoping to extricate myself from CE for a while to finish off a paper explaining why climate sensitivity as currently defined can neither be measured nor estimated with an
error bar less than 1 C per doubling, and proposing a different definition that shrinks the
error bar
by an
order of magnitude.
However the ARGO
errors are much much smaller than the pre-ARGO measurements (maybe
by two
orders of magnitude, one for each temperature reading and one for the sparseness
of sampling?).
You want to dismiss these issues even though
by doing so you introduce an
error in the uncertainty reduction
of ten
orders of magnitude.
As you can see, we can't trust any individual data point to better than + / - 5 degs yet
by taking the average
of 100 data points the
error drops
by an
order of magnitude to (The
error falls as the square root
of the number
of data points) to give an accuracy
of a fraction
of a degree.
I'm guessing that monthly
error will differ from month to month — but not
by, say,
orders of magnitude, or anything close to that much.
Despite the faux precision
of naive fanatics —
errors from satellite altimetry exceed annual sea level rise
by an
order of magnitude.
There can be no credible expectation that this tuning / calibration procedure can reduce the
error by two
orders of magnitude as required to measure changes
of Earth's energy balance to an accuracy
of 0.1 W / m2.»
I made a math
error and was off
by 3
orders of magnitude — the actual temperature change is 0.1 degrees, and I can easily see that as measureable.
