Title: Tropospheric radiative forcing of O{sub 3} for the 1994 IPCC report

We have determined the tropospheric radiative forcing Of O{sub 3} in the 175-735 nm (UV-Visible) wavelength range plus the 500-1650 cm{sup {minus}1} (Infrared) wavenumber range in accordance with a set of IPCC test cases provided to all interested modeling groups. The atmospheric test cases involved perturbed ozone scenarios in a McClatchey mid-latitude summer, clear sky, model atmosphere. A new short wave radiative transfer code has been developed to calculate the radiative forcing in the 175-735 nm wavelength range. The IR radiative forcing was calculated using a correlated k-distribution transmission model. The tropospheric radiative forcing values obtained for the IR spectral region and the UV-Visible spectral region lie in the middle of the range of preliminary values submitted from all of the models used in the IPCC test calculations.
