Wildfires are important sources of atmospheric reactive nitrogen. The reactive nitrogen
species partitioning generally depends on fire characteristics. One reactive nitrogen …

The bushfires that occurred in Australia in late 2019 and early 2020 were unprecedented in
terms of their scale, intensity, and impacts. Using nitrogen dioxide (NO 2) and carbon …

Megafires occurred in Australia during the 2019/2020 bushfire season, leading to enhanced
concentrations of many tropospheric pollutants. Here, we report on a fire plume with …

Reactive nitrogen (Nr) within smoke plumes plays important roles in the production of ozone,
the formation of secondary aerosols, and deposition of fixed N to ecosystems. The Western …

Biomass burning emits an estimated 25% of global annual nitrogen oxides (NO x), an
important constituent that participates in the oxidative chemistry of the atmosphere …

Nitrous acid (HONO) is a precursor of the hydroxyl radical in the atmosphere, which controls
the degradation of greenhouse gases, contributes to photochemical smog and ozone …

Nitrogen oxides (NO x) play key roles in atmospheric chemistry, air pollution, and climate.
While the largest fraction of these reactive gases is released by anthropogenic emission …

We use observations of fire radiative power (FRP) from the Moderate Resolution Imaging
Spectroradiometer~(MODIS) and tropospheric NO 2 column measurements from the Ozone …

Past studies suggest that forest fires contribute significantly to the formation of ozone in the
troposphere. However, the emissions of ozone precursors from wildfires, and the …

Biomass burning represents both a significant and highly variable source of NO x to the
atmosphere. This variability stems from both the episodic nature of fires, and from fire …
