The First 30 Years of GEWEX
by Graeme Stephens et al.

In
this chapter we prove the validity of the all-sky equations, and the
accuracy of the integer system, on a recently published global energy
flow diagram
(Stephens et al. 2023, BAMS)
We projected the complete integer energy flow system on the diagram, with the best-fit unit of 26.68 ± 0.01 Wm-2.
TSI with spherical weighting is 1360.68 ± 0.5 Wm-2, with the geodetic weighting factor of 4.0034, TSI = 1361.84 Wm-2.
The differences from the N-positions are shown in circles in Wm-2; the least is 0.03 Wm-2 in Incoming Solar, the largest is 3.38 Wm-2 in Surface Reflection.
All-sky equation (3) is satisfied with a difference of 0.09 Wm-2, Eq. (4) is satisfied with a difference of 0.12 Wm-2.
These equations express the physical science basis of Earth's global mean energy flow system.
The values shown are the result of 30 years of global energy and water cycle study (GEWEX).
It is "official", published in the Bulletin of the American Meteorological Society.
We expect that any future climate assessment, IPCC Report, sensitivity study, radiative forcing and cloud feedback estimate should strictly satisfy these constraint equations, within the given accuracy.
