TL;DR: In this article, the authors used positive matrix factorization (PMF) to examine the systematics of nitrogen emissions from 75 stack fires in western US wildfires and found that CO2 is recommended as a marker for Nr emissions.
Journal ArticleDOI
Speciated online PM 1 from South Asian combustion sources – Part 1: Fuel-based emission factors and size distributions

TL;DR: In this article, an online measurement of submicron aerosol (PM 1 ) emissions was conducted as part of the Nepal Ambient Monitoring and Source Testing Experiment (NAMaSTE) to investigate and report emission factors (EFs) and vacuum aerodynamic diameter (dva ) size distributions from prevalent but poorly characterized combustion sources.
Journal ArticleDOI
Aerosol Mass and Optical Properties, Smoke Influence on O 3 , and High NO 3 Production Rates in a Western U.S. City Impacted by Wildfires
TL;DR: This article evaluated the smoke from wild and prescribed fires using downwind measurements that include both inert tracers to test production and transport and reactive species to detect reactive species in the smoke and evaluate the smoke.
Journal ArticleDOI
Kinetic, thermochemical, and spectroscopic study of chlorine oxide (Cl2O3)
TL;DR: In this article, the UV absorption spectrum of Cl 2 O 3 between 220 and 320 nm was measured using time-resolved transient absorption, which peaks at 267 nm with a cross section of (1.60 -0.22 + 0.35 )×10 -17 cm 2 (2σ error limits including estimated systematic errors).
Journal ArticleDOI
Highly Speciated Measurements of Terpenoids Emitted from Laboratory and Mixed-Conifer Forest Prescribed Fires.

TL;DR: Speciated measurements of terpenoids in smoke derived from diverse ecosystems and fire regimes may improve air quality predictions downwind of wildland fires.
