|The major TSI datasets all agree there has been a large fall since 2003, in terms of 11 year smoothing (which is obviously required to remove the sunspot cycle and reveal the underlying trend). The SORCE/TIM reconstruction shows the fall starting in 1994. The “composite TSI” is that used by David to drive the model, averaging Lean 2000 (to the end of 2008), PMOD, and ACRIM (from the start of 1992). Source Jo Nova|

The nature of Neptune’s increasing brightness: evidence for a seasonal response
L.A. Sromovsky, P.M. Fry, S.S. Limaye, and K.H. Bainesb
Hubble Space Telescope (HST) observations in August 2002 show that Neptune’s disk-averaged reflectivity increased significantly since 1996, by 3.2 ± 0.3% at 467 nm, 5.6 ± 0.6% at 673 nm, and 40 ± 4% in the 850–1000 nm band, which mainly results from dramatic brightness increases in restricted latitude bands. When 467-nm HST observations from 1994 to 2002 are added to the 472-nm ground-based results of Lockwood and Thompson (2002, Icarus 56, 37–51), the combined disk-averaged variation from 1972 to 2002 is consistent with a simple seasonal model having a hemispheric response delay relative to solar forcing of 30 years (73% of a full season).
