Three‐Decade Dust Climatology and Trend (1988–2022) From Ground Monitoring Over the Western United States

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Airborne dust exerts myriad effects on climate, weather, human health and safety. In this study, 35‐year records (1988–2022) of ground aerosol observations were analyzed to identify windblown dust events from 18 Interagency Monitoring of Protected Visual Environments (IMPROVE) stations over the western United States (US).

New methods provide a 300‐year perspective on modern area burned in two wilderness areas of the southwest United States

Abstract Climate change, expanding human ignitions, and increased fuels from fire exclusion are driving increases in area burned and fire severity in dry conifer forests of the western United States. Increasing area burned is occurring against the backdrop of a large fire deficit caused by over a century of fire exclusion.

The southwest Kalahari dune field does not emit dust post‐fire despite a lack of vegetation and above‐threshold winds

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
The southwest Kalahari dune field has resident fine grains which may be emitted as mineral dust after protective vegetation is removed by fire. However, low wind speeds, high initial surface cover, and the protective effect of biocrusts result in the low possibility of the southwest Kalahari emitting dust post‐fire.
