Comment on article by Sansó et al. (English) Zbl 1330.86026
Summary: Sansó, Forest and Zantedeschi (SFZ) [B. Sansó et al., ibid. 3, No. 1, 1–37 (2008; Zbl 1330.86029)] have presented an excellent analysis that combines limited computer simulations with historical observations to provide inference about key climate system parameters. The Bayesian formulation used in this analysis allows the incorporation of a number of different sources of uncertainty in the final inference. We appreciate such a collaboration requires a substantial amount of effort from all involved. There is not much to criticize here. Most of our comments, which are motivated by the case study, apply generally to analyses involving the calibration of a physics-based simulation model using physical observations.
