Aghedo, A.M., K.W. Bowman, H.M. Worden, S.S. Kulawik, D.T. Shindell, J.F. Lamarque, G. Faluvegi, M. Parrington, D.B.A. Jones, and S. Rast, 2011: The vertical distribution of ozone instantaneous radiative forcing from satellite and chemistry climate models. J. Geophys. Res., 116, D01305, doi:10.1029/2010JD014243.

We evaluate the instantaneous radiative forcing (IRF) of tropospheric ozone predicted by four state-of-the-art global chemistry climate models (AM2-Chem, CAM-Chem, ECHAM5-MOZ and GISS-PUCCINI) against ozone distribution observed from the NASA Tropospheric Emission Spectrometer (TES) during August 2006. The change in the top-of-the-atmosphere radiative flux to vertical and spatial discrepancies between model and TES ozone was calculated through all-sky instantaneous radiative forcing kernels from TES. Through this technique, we find total tropospheric IRF biases from -0.4 to +0.7 W/m2 over large regions within the tropics and mid-latitudes, due to ozone differences over the region in the lower and middle troposphere, enhanced by persistent bias in the upper-troposphere lower-stratospheric region. The zonal mean biases also range from -30 to +40 mW/m2 for the models. However, the ensemble mean total tropospheric IRF bias is less than 0.2 W/m2 within the entire troposphere.
