Biomass Burning Emission Inventory from Burnt Area Data Given by the SPOT-VEGETATION System in the Frame of TRACE-P and ACE-Asia Campaigns
One of the main uncertainties in the estimation of the climatic impact of aerosols is
linked to our knowledge of gas and aerosol emissions. This is particularly crucial
over Asia, where a strong regional fingerprint is observed, with different emission
types, depending on the various vegetation and climate conditions (biomass burning
emissions) and on the very fast changes of the population and industrialization
(biofuel and fossil fuel emissions). The main contribution of this work is to derive a
biomass burning inventory of 1 1 over Asia (the Asian biomass burning
inventory (ABBI)) for gases and particles for the Aerosol Characterization
Experiment-Asia (ACE-Asia) and Transport and Chemical Evolution Over the Pacific
(TRACE-P) campaign period (March to May 2001) in 2001. In this paper we apply
new estimates of burnt biomass area to estimate emissions. The method is based on
burnt areas (GBA2000 project; Tansey et al. (2002) and Gregoire et al. (2003))
obtained from 1 km resolution SPOT-VEGETATION satellite data. Regional-scale
maps of burnt areas are produced, and then spatial and temporal emission distribution
are obtained from biomass density and emission factors. Strength and weaknesses
associated with the use of satellite products are discussed, including the problem of
subpixel classification and the lack of validation data for the accuracy assessment of
the products for the studied area. Estimated emissions are compared with ACE-Asia
and TRACE-P Modeling and Emission Support System (ACESS) climatological
estimates. In addition, interannual variability is estimated by preparing inventories for
the years 2000 and 2001.
