Uncertainty Estimates for Routine Temperature Data Sets Part Two.
In short, what is the proper magnitude of the uncertainty associated with such routine daily temperature measurements?
Uncertainty Estimates for Routine Temperature Data Sets
Modern climate research commonly fails adequate recognition of three guiding principles about uncertainty.
An Examination of Two of The Changes to Raw Data That Are Included in the ACORN-SAT 2.2 Darwin Maximum Temperature Reconstruction.
There appears to be no valid reason to lower Darwin maximums by 0.67C for all years prior to 1980 all the way back to the start of the record in…
