Proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) is a technique
commonly used to measure ambient volatile organic compounds (VOCs) in urban, rural, and …

Abstract Purpose of Review During the past decade, weather and climate extremes,
enhanced by climate change trends, have received tremendous attention because of their …

Biomass burning particulate matter (BBPM) affects regional air quality and global climate,
with impacts expected to continue to grow over the coming years. We show that studies of …

As wildland fires become more frequent and intense, fire smoke has significantly worsened
the ambient air quality, posing greater health risks. To better understand the impact of …

Volatile organic compounds (VOCs) emitted from biomass burning impact air quality and
climate. Laboratory studies have shown that the variability in VOC speciation is largely …

We present a comparison of fast-response instruments installed onboard the NASA DC-8
aircraft that measured nitrogen oxides (NO and NO 2), nitrous acid (HONO), total reactive …

Abstract The COVID-19 stay-at-home orders issued in the United States caused significant
reductions in traffic and economic activities. To understand the pandemic's perturbations on …

Detailed chemical characterization of biomass burning organic aerosol (OA) was performed
using a synergistic combination of multimodal mass spectrometry techniques. OA was …

Abstract Fire Influence on Regional to Global Environments and Air Quality was a
