Spatiotemporal discrepancies between satellite- and inventory-derived estimates of global ammonia emissions

Bottom-up inventories and satellite-constrained estimates of ammonia emissions often diverge, but the conditions driving these discrepancies remain unclear. Here we compare monthly global estimates at 0.1° resolution from 2008 to 2016 using a normalised discrepancy index. Satellite-constrained emissions are higher on a...

Assessing ozone dynamics during the 2023 summer STAQS field campaign using synergistic observations and model simulations

NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) geostationary satellite sensor provides high temporal and spatial resolution measurements critical for monitoring air quality. During the Synergistic TEMPO Air Quality Science (STAQS) component of the 2023 AGES+ campaign, extensive surface, airborne, and...

Urban-Scale Associations of PM2.5 with Aerosol Light Absorption, Meteorology, and Regional Transport in a Mediterranean Area Using FAIR-Oriented Environmental Data

Atmospheric particulate-matter variability reflects the combined effects of emissions, meteorology, and regional transport, and its interpretation benefits from the integration of complementary observations. This study combines two years (2023–2024) of aerosol light absorption at 880 nm (Abs880), PM2.5, PM10, and meteo...

Surface temperatures drive strong seasonality in urban reactive carbon emissions

Urban air quality is affected by diverse volatile organic compounds (VOCs), and prior studies reveal a need to understand their seasonal sources. We combine high-resolution mass spectrometry with eddy covariance to quantify VOC fluxes from an urban/suburban New York site during summer and winter. Emissions are strongly...

INFLUENCE OF SURFACE METEOROLOGICAL DATA ON AERMOD-SIMULATED TSP DISPERSION FROM MDF FACTORY

This study evaluates the influence of surface meteorological data on the dispersion of Total Suspended Particulates (TSP) emitted from a Medium Density Fiberboard (MDF) factory in Southern Thailand using AERMOD model. Meteorological inputs from two nearby stations, Khohong and Sadao, were applied to simulate emissions...

Dynamics of the spatiotemporal correlation between Aerosol Optical Depth satellite data and PM2.5 surface monitoring: An exploratory approach

PM2.5 is a major air pollutant with diverse natural and anthropogenic sources, which significantly impacts human health and the environment. Remote sensing serves as a complementary resource for air-monitoring networks, providing valuable information on the spatiotemporal patterns of air pollutants at a global scale Th...
