in other atmospheric forcing (winds, surface air
temperature, and water fluxes).

I used the word «consistent» because observational data are not yet accurate enough to prove the existence of an imbalance (e.g. 0.9 W / m ^ 2) capable of
significant temperature effect but too small to be precisely estimated as the exact

in the range of 239 W / m ^ 2.

My point at that time was that the number of CRN 1 and CRN 2 stations was very small and that given the noisy data for

difference in trends or a larger number of stations
in those classifications.
In fact, the lower - tropospheric
