Relationships Between Aerosols, Warm Clouds, and Meteorological Factors Associated With Environmental Conditions Derived From Multiyear ARM Observations

Abstract We derive new aspects between clouds, aerosols, and meteorological factors using latest observations. We analyze multiyear measurements of atmospheric physical properties including warm clouds and aerosols collected at Atmospheric Radiation Measurement continental and ma...

Fire at the boundary: Airborne toxic metals from the 2025 Los Angeles urban firestorm

Urban fire smoke is chemically distinct from wildland fire smoke, yet remains poorly understood. Using real-time airborne trace element measurements during the 2025 Los Angeles Eaton urban firestorm, we show that the plume evolved rapidly as fire transitioned from structures to w...
