Resumo
The 17-year long record of carbon monoxide (CO) concentrations from the MOPITT satellite instrument is uniquely
suited for studying the interannual variability of biomass burning emissions. Data assimilation methods based on
Ensemble Kalman Filtering are currently being developed to infer CO emissions within the Amazon Basin from
MOPITT measurements along with additional datasets. The validity of these inversions will depend on the
characteristics of the MOPITT CO retrievals (e.g., retrieval biases and vertical resolution) as well as the representation
of chemistry and dynamics in the chemical transport model (CAM-Chem) used in the data assimilation runs. For
example, the assumed vertical distribution ("injection height") of the biomass burning emissions plays a particularly
important role.
We will review recent progress made on a project to improve biomass burning emission inventories for the Amazon
Basin. MOPITT CO retrievals over the Amazon Basin are first characterized, 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 MOPITT retrieved lower-tropospheric CO concentrations. The seasonal and
geographical variability of smoke injection height over the Amazon Basin is then analyzed using a MISR plume height
climatology. This work has led to the development of a new fire emission injection height parameterization that was
implemented in CAM-Chem and GEOS-Chem.. Finally, we present initial data assimilation results for the Amazon
Basin and evaluate the results using available field campaign measurements.
