FEBRUARY 2003: Biomass burning emission inventory with daily resolution
 |
|
This animation shows the daily biomass burning emission inventory of CO over Asia during the TRACE-P aircraft mission (Feb-April 2001). This inventory was developed from AVHRR fire observations, by correcting for scan angle biases and data gaps. Biomass burning exhibits large day-to-day variability reflecting weather, agricultural practices, and accidental fires. Outflow from Asia associated to fire activity peaks in the Spring. Some of the strongest areas of burning in Asia are Burma, Thailand and northeast India. This inventory was implementented in the GEOS-CHEM model to investigate the impact of daily vs. monthly resolution of biomass burning emissions. We find that improvement in the simulation of TRACE-P observations is found when using 2001 monthly versus climatological monthly emissions, but using 2001 daily emissions does not offer further improvement. This work was led by Colette Heald and a full account is given in Heald et al. [2003a]. |
