The hydroxyl radical (OH) plays a central role in tropospheric chemistry, as well as
influencing the lifetimes of some greenhouse gases. Because of limitations in our ability to …

The frequency of wildfires in the western United States has escalated in recent decades.
Here we examine the impacts of wildfires on ground-level ozone (O3) precursors and the O3 …

Tropospheric nitrogen dioxide (NO 2) measured from satellites has been widely used to
track anthropogenic NO x emissions, but its retrieval and interpretation can be complicated …

Extensive airborne measurements of non-methane organic gases (NMOGs), methane,
nitrogen oxides, reduced nitrogen species, and aerosol emissions from US wild and …

The monitoring and analysis of the spatiotemporal distribution of anthropogenic carbon
emissions is an important part of realizing China's regional “dual carbon” goals; that is, the …

Tropospheric vertical column densities (VCDs) of nitrogen dioxide (NO 2) retrieved from sun-
synchronous satellite instruments have provided abundant NO 2 data for environmental …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …

Abstract The Geostationary Environment Monitoring Spectrometer (GEMS) is the world's first
geostationary instrument that monitors hourly gaseous air pollutant levels, including nitrogen …

Abstract This Algorithm Theoretical Basis Document (ATBD) describes the retrieval
algorithm and sensitivities of the Version 3 cloud product derived from the spectra collected …

Nitrogen dioxide (NO 2) is a major air pollutant. Tropospheric NO 2 vertical column densities
(VCDs) retrieved from sun-synchronous satellite instruments have provided abundant NO 2 …
