Abstract

Two papers published in the early 1990s significantly influenced the subsequent design of ARM and its adoption of the single-column model (SCM) approach. The first paper, by Cess et al. (1990), showed a threefold difference in the sensitivity of climate models in a surrogate climate change that is attributed largely to cloud–climate feedbacks. The second paper, by Ellingson et al. (1991), reported 10%–20% difference in the calculated broadband radiation budget and 30%–40% difference in the radiative forcing of greenhouse gases in the radiation codes of climate models. At that time, the U.S. Department of Energy (DOE) had a program to study the climate impact of the increasing amount of carbon dioxide in the atmosphere. Results from these two papers pointed to the major uncertainties in climate forcing and feedbacks of climate models.
