Pekka, the approximately uniform prior in Y is, according to F&G, a consequence of a) the choice of an OLS regression type, b) the fact that the combined errors in the measurements of forcings and net radiative balance were very much greater than errors in
measurements of the surface temperature, and c) the assumption of normal distributions in the errors of the three observables.
My understanding is that a uniform prior in S (and hence, equivalently, a 1 / Y ^ 2 prior in Y) would be the correct uninformative reference prior (that which has least effect on the posterior PDF) if way stayed with Forster & Gregory's OLS regression method to estimate Y, if and only if the magnitude of the errors in
measurements of the surface temperature were much less than combined errors in the measurements of forcings and net radiative balance, the opposite of what Forster & Gregory's error analysis showed.
