Resumo
We analyze satellite retrievals of carbon monoxide
from the MOPITT (Measurements of Pollution in the Troposphere)
instrument over the Amazon Basin, focusing on
the MOPITT Version 6 “multispectral” retrieval product (exploiting
both thermal-infrared and near-infrared channels).
Validation results based on in situ vertical profiles measured
between 2010 and 2013 are presented for four sites in the
Amazon Basin. Results indicate a significant negative bias in
retrieved lower-tropospheric CO concentrations. The possible
influence of smoke aerosol as a source of retrieval bias
is investigated using collocated Aerosol Robotic Network
(AERONET) aerosol optical depth (AOD) measurements at
two sites but does not appear to be significant. Finally, we
exploit the MOPITT record to analyze both the mean annual
cycle and the interannual variability of CO over the Amazon
Basin since 2002.
