Database development for spatial and temporal distribution of biomass burning In Northern Thailand

In all estimations the large uncertainties associated with inherent in burned areas, fuel loads, combustion
factors and emission factors. An activity data were taken directly from official statistics and/or estimated using a
single parameter for the whole county (Garivait et al., 2004; Streets et al., 2003). A few measurements have been
made to determine spatial and temporal distributions of characteristic of biomass stoves in local scale as historical
data to improve the estimating accuracy of air quality modeling. However, in Northern Thailand does not have report
about air pollutant estimates from open burning separately from types of vegetation land cover. Therefore, an
accurate estimation of characteristics of burned areas, fuel loads, combustion factors and emission factors of
vegetation burning and up-to-date information in local scale are urgently needed and remain to develop.
