Improvement of MM5 Model Forecast by Ingesting Newly Archived Satellite Data and Estimation of Forest Fire Emissions Contribution to Ozone Peaks Using CMAQ Modeling System
… in California and Nevada from grid-averaged wildfire emissions from NEI02 (National Emissions Inventory 2002); and (3) investigation of two prescribed fire events to the contribution of O3 peaks to background concentration levels. The 3D-Var code was first modified to use WINDSAT wind vectors as …

Investigating the effect of variability in biomass burning emissions inventories on GEOS-Chem modeled trace gas and aerosol concentrations
Over the past century, global wildfire activity has intensified due to increasing mean temperatures. However, emissions inventories used for modeling the impact of fires on air quality and climate exhibit several discrepancies in emissions estimates, largely due to the different types of satellite …

A 2007 aircraft-based study of plumes from biomass burning origin from Mexico and Central America advected over south Texas and the western Gulf of Mexico.
… may be diverse ranging from individual local fire emissions to medium range transport of biomass burning.

Measurements of Reactive Trace Gases and Variable Ozone Formation Rates in South Carolina Biomass Burning Plumes
… and global importance. In the US, prescribed fire and wildfire are the two major fire types and they occur frequently. Prescribed fires are ignited to improve and aid forest health, maintenance, and management. Land managers strive to minimize the impact of smoke on local communities. However, …

Quantifying the immediate carbon emissions from El Niño-mediated wildfires in humid tropical forests
Wildfires produce substantial CO2 emissions in the humid tropics during El Niñomediated extreme droughts, and these emissions are expected to increase in coming decades. Immediate carbon emissions from uncontrolled wildfires in human-modified tropical forests can be considerable owing to high …

Primary and secondary emissions from upland fires in Ireland
Emissions from wildfires have detrimental effects on air quality, climate change and human health. Despite frequent occurrence of wildfires and prescribed agricultural burns in upland areas, data on wildfire emissions in Ireland is scarce. This work was conducted as part of FLARES (Fire, Land and …

Nutrient Cycling Between Litters and Soil after Fire in Native Woodland and Pinus radiata Plantations
Fire can change both the quantity and nature of soil organic matter during the event and can affect organic matter inputs after the event. These changes may affect the microbial biomass, nutrient availability and nutrient cycling, and may have flow on effects on soil carbon stocks and cycling. …

Spatiotemporal Distribution of Siberian Wildfires and Impacts from Meteorological and Climatic Factors
Wildfire is a major disturbance affecting carbon cycling, land–atmosphere energy exchange, and ecological security in high-latitude ecosystems. Siberia is one of the most fire-prone regions in the high latitudes of the Northern Hemisphere, and the spatiotemporal variability of its wildfire activity …
