Voulgarakis, A., and D.T. Shindell, 2010: Constraining the sensitivity of regional climate with the use of historical observations. J. Climate, 23, 6068-6073, doi:10.1175/2010JCLI3623.1.

We present a novel method for calculating how sensitive regional climate is to radiative forcings, based on global surface temperature observations. Forcings that originate both in the region of interest and outside of it are taken into account. We find that the transient temperature sensitivity parameter (β, defined as the observed temperature response per unit forcing) for 50°S-25°N can be constrainted better than for the rest of the globle. The average β in this region is 0.35°C/(W/m2). The models used in the IPCC (AR4) 1% yr-1 CO2 increase experiment exhibit a β in this region which, on average, is higher by 35%. Our results show that 50°S-25°N β may provide a more valuable constraint for model evaluation than global mean climate sensitivity.
