Monitoring of Transport of Vegetation Burning Emissions Over South America
The Atmospheric Sciences Department, University of São Paulo (Departamento de Ciencias Atmosfericas – Universidade de São Paulo) studies atmospheric transport of vegetation burning emissions in the Amazon and Central Brazil through a numerical simulation using the atmospheric model RAMS-CSU (Regional Atmospheric Modeling System). A model of gases and particles source emissions is introduced, associated with vegetation burning in South America tropical forest and savanna, spatially and temporally distributed and daily assimilated, according to the vegetation burning spots defined by remote sensing (GOES-8 ABBA Preliminary Fire Products produced by UW-Madison CIMSS GOES Biomass Burning Monitoring Program, see:
http://cimss.ssec.wisc.edu/cgi-bin/fire99.cgi). The advection, in a resolved scale, and turbulent transport, in a sub-grid scale, are resolved using RAMS model parameterizations. A transport sub-grid parameterization, associated to wet and deep circulation not explicitly resolved by the model, due ist low spatial resolution, is introduced. Sinks, associated with generic process of removal/transformation of gases/particles, are parameterized and introduced in the mass conservation equation. Products: Carbon monoxide at five levels (1000m, 3500m, 5000m, 7500m, and 10000m), carbon monoxide column average, number and size of fires.
