abstract = "The scope of this work was to evaluate simulated carbon monoxide
(CO) and aerosol optical depth (AOD) from the CAM-chem model
against observed satellite data and additionally explore the
empirical relationship of CO, AOD and fire radiative power (FRP).
The simulated seasonal global concentrations of CO and AOD were
compared, respectively, with the Measurements of Pollution in the
Troposphere (MOPITT) and the Moderate-Resolution Imaging
Spectroradiometer (MODIS) satellite products for the period
20102014. The CAM-chem simulations were performed with two
configurations: (A) tropospheric-only; and (B) tropospheric with
stratospheric chemistry. Our results show that the spatial and
seasonal distributions of CO and AOD were reasonably reproduced in
both model configurations, except over central China, central
Africa and equatorial regions of the Atlantic and Western Pacific,
where CO was overestimated by 1050 ppb. In configuration B, the
positive CO bias was significantly reduced due to the inclusion of
dry deposition, which was not present in the model configuration
A. There was greater CO loss due to the chemical reactions, and
shorter lifetime of the species with stratospheric chemistry. In
summary, the model has difficulty in capturing the exact location
of the maxima of the seasonal AOD distributions in both
configurations. The AOD was overestimated by 0.1 to 0.25 over
desert regions of Africa, the Middle East and Asia in both
configurations, but the positive bias was even higher in the
version with added stratospheric chemistry. By contrast, the AOD
was underestimated over regions associated with anthropogenic
activity, such as eastern China and northern India. Concerning the
correlations between CO, AOD and FRP, high CO is found during
MarchAprilMay (MAM) in the Northern Hemisphere, mainly in China.
In the Southern Hemisphere, high CO, AOD, and FRP values were
found during August SeptemberOctober (ASO) due to fires, mostly in
South America and South Africa. In South America, high AOD levels
were observed over subtropical Brazil, Paraguay and Bolivia.
Sparsely urbanized regions showed higher correlations between CO
and FRP (0.70.9), particularly in tropical areas, such as the
western Amazon region. There was a high correlation between CO and
aerosols from biomass burning at the transition between the forest
and savanna environments over eastern and central Africa. It was
also possible to observe the transport of these pollutants from
the African continent to the Brazilian coast. High correlations
between CO and AOD were found over southeastern Asian countries,
and correlations between FRP and AOD (0.50.8) were found over
higher latitude regions such as Canada and Siberia as well as in
tropical areas. Higher correlations between CO and FRP are
observed in Savanna and Tropical forests (South America, Central
America, Africa, Australia, and Southeast Asia) than FRP x AOD. In
contrast, boreal forests in Russia, particularly in Siberia, show
a higher FRP x AOD correlation than FRP x CO. In tropical forests,
CO production is likely favored over aerosol, while in temperate
forests, aerosol production is more than CO compared to tropical
forests. On the east coast of the United States, the eastern
border of the USA with Canada, eastern China, on the border
between China, Russia, and Mongolia, and the border between North
India and China, there is a high correlation of CO x AOD and a low
correlation between FRP with both CO and AOD. Therefore, such
emissions in these regions are not generated by forest fires but
by industries and vehicular emissions since these are densely
populated regions.",
