	<abstract content_type="html">Estimates of the radiative forcing due to anthropogenically-produced
      tropospheric O&lt;sub&gt;3&lt;/sub&gt; are derived primarily from models. Here, we
      use tropospheric ozone and cloud data from several instruments in the
      A-train constellation of satellites as well as information from the
      GEOS-5 Data Assimilation System to accurately estimate the radiative
      effect of tropospheric O&lt;sub&gt;3&lt;/sub&gt; for January and July 2005. Since we
      cannot distinguish between natural and anthropogenic sources with the
      satellite data, our derived radiative effect reflects the unadjusted
      (instantaneous) effect of the total tropospheric O&lt;sub&gt;3&lt;/sub&gt; rather
      than the anthropogenic component. We improve upon previous estimates
      of tropospheric ozone mixing ratios from a residual approach using the
      NASA Earth Observing System (EOS) Aura Ozone Monitoring Instrument
      (OMI) and Microwave Limb Sounder (MLS) by incorporating cloud pressure
      information from OMI. We focus specifically on the magnitude and
      spatial structure of the cloud effect on both the short- and long-wave
      radiative budget. The estimates presented here can be used to evaluate
      the various aspects of model-generated radiative forcing. For example,
      our derived cloud impact is to reduce the radiative effect of
      tropospheric ozone by ~16%. This is centered within the
      published range of model-produced cloud effect on instantaneous
      radiative forcing.</abstract>
