Short-lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

Surface ozone data from the Chinese Ministry of Ecology and Environment (MEE) network
show sustained increases across the country over the 2013–2019 period. Despite Phase 2 …

Particulate matter (PM 2.5) concentrations in China have decreased significantly in recent
years, but surface ozone (O 3) concentrations showed upward trends at more than 71% of …

Urban ozone (O3) formation can be limited by NO x, VOCs, or both, complicating the design
of effective O3 abatement plans. A satellite-retrieved ratio of formaldehyde to NO2 …

Atmospheric carbon monoxide (CO) concentrations have been decreasing since 2000, as
observed by both satellite-and ground-based instruments, but global bottom-up emission …

In 2022, many Chinese cities experienced lockdowns and heatwaves. We analyzed ground
and satellite data using machine learning to elucidate chemical and meteorological drivers …

Over the last five decades, Earth's atmosphere has been extensively monitored from space
using different spectral ranges. Early efforts were directed at improving weather forecasts …

Photochemical ozone (O3) formation in the atmospheric boundary layer occurs at both the
surface and elevated altitudes. Therefore, the O3 formation sensitivity is needed to be …

Observational data indicate increasing trends of surface ozone (O3) in China, despite
emission controls that have resulted in reductions of precursor emissions. Here, we explore …

The Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel-5 Precursor (S5P)
satellite is a valuable source of information to monitor the NOx emissions that adversely …
