The MOPITT (Measurements Of the Pollution In The Troposphere) instrument onboard the NASA/Terra platform is a nadir looking
gas correlation radiometer which measures radiances in the infrared. MOPITT retrievals have a horizontal resolution of 22km
by 22km. The retrieved CO profiles are provided as seven vertically integrated CO concentrations and show between 1 to 2
degrees of freedom. The sensitivity of the instrument is maximal in the mid-troposphere.
Here we present results of the first multi-year inversion of CO global surface sources based on MOPITT CO retrievals. We have
implemented a recursive synthetic Bayesian time-dependent inversion using the global CTM (MOZART) driven with NCEP winds and
the MOPITT CO retrievals averaged monthly and binned horizontally at the model resolution (2.8x2.8deg). A global inventory
for CO anthropogenic direct sources has been derived for the time period spanning April 2000 to December 2003. The MOPITT
data show a large inter-annual variability of the CO load in several regions. Some of this variability, especially in the
boreal regions, can be linked to biomass burning emissions. The 4-year emission inventory will be described and compared with
other top-down and bottom-up emission estimates. We will also present results of several sensitivity tests for the inversion
and discuss the limitations of the method.
