<abstract>
<p>The first study of the global atmospheric distribution of carbon
tetrachloride (CCl&lt;sub&gt;4&lt;/sub&gt;), as a function of altitude and latitude, was
performed using solar occultation measurements obtained by the Atmospheric
Chemistry Experiment (ACE) mission using Fourier transform spectroscopy. A
total of 8703 profile measurements were used in the study taken between
February 2004 and August 2007. The zonal distribution of carbon
tetrachloride displays a slight hemispheric asymmetry and decreasing
concentration with increasing altitude at all latitudes. Maximum carbon
tetrachloride concentrations are situated below 10 km in altitude with VMR (Volume Mixing Ratio)
values of 100–130 ppt (parts per trillion). The highest concentrations are
located about the equator and at mid-latitudes, particularly for latitudes
in heavily industrialised regions (20–45&amp;deg; N), with values declining
towards the poles. Global distributions obtained from ACE were compared with
predictions from three chemistry transport models. The ACE dataset gives
unique global and temporal coverage of carbon tetrachloride and its
transport through the atmosphere. An estimated lifetime for carbon
tetrachloride of 34&amp;plusmn;5 years was determined through correlation with
CFC-11.</p>
