Estimating emissions from fires in North America for air quality modeling

摘要: Fires contribute substantial emissions of trace gases and particles to the atmosphere. These can impact air quality even climate. We have developed a modeling framework estimate from fires in North parts Central America (10–711N 55–1751W) by taking advantage combination complementary satellite ground-based data refine estimates fuel loadings. Various drivers, including MODIS Thermal Anomalies Product, Global Land Cover Characteristics 2000 dataset, Vegetation Continuous Fields Product were used conjunction with mined literature determine fire location timing, loadings, emission factors. Daily particulate matter numerous estimated using this method for three years (2002–2004). Annual differ as much factor 2 (CO ranged 22.6 39.5 Tg yr � 1 ). Regional variations correspond different seasons within region. For example, highest Mexico occur late spring whereas United States Canada during summer months. Comparisons these results other published CO show reasonable agreement, but uncertainties remain estimation techniques. suggest methods whereby future models reduce uncertainties. r 2006 Published Elsevier Ltd.
