The ORNL DAAC announces the release of emission factors from 19 deforestation fires in Mato Grosso, Para, and Amazonas, Brazil.
LBA-ECO TG-10 Fire Emission Factors in Mato Grosso, Para, and Amazonas, Brazil: 2004 . Data set prepared by R.J. Yokelson, T. Karl, P.E. Artaxo, D. R. Blake, T. J. Christian, D.W.T. Griffith, A.B. Guenther, and W.M. Hao. This data set provides derived emission factors (EFs) for PM10 (particulate matter up to 10 micrometers in size), O3, CO2, CO, NO, NO2, HONO, HCN, NH3, OCS, DMS, CH4, and up to 48 non-methane organic compounds (NMOC) from the Tropical Forest and Fire Emissions Experiment (TROFFEE). EFs were determined for 19 deforestation fires from pristine tropical forest and several plantations in Mato Grosso, Para, and Amazonas, Brazil. The combined output of several of these fires created a massive megaplume more than 500-km wide and covered a large area in Brazil, Bolivia, and Paraguay for about one month.
LBA was an international research initiative under the leadership of Brazil. The project focused on the climatological, ecological, biogeochemical, and hydrological functions of Amazonia; the impact of land use change on these functions; and the interactions between Amazonia and the Earth system. The LBA-ECO component, which was funded by NASA, focused on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia? "
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
