El Chichón’s “surprise” eruption in 1982: Lessons for reducing volcano risk

open access: yesGeofísica Internacional, 2009
Durante una semana (marzo 28- abril 4, 1982), tres erupciones explosivas (VEI 5) del volcán El Chichón causaron el peor desastre volcánico en la historia de México.

Maize Yield Changes Under Sulfate Aerosol Climate Intervention Using Three Global Gridded Crop Models

open access: yesEarth's Future, Volume 13, Issue 2, February 2025.
Abstract As the severity of climate change and its associated impacts continue to worsen, schemes for artificially cooling surface temperatures via planetary albedo modification are being studied. The method with the most attention in the literature is stratospheric sulfate aerosol intervention (SAI).

The Hawaii Dust Regime: Patterns and Variability in Aerosol Mineral Dust From MERRA‐2 at Station ALOHA and the Hawaii Aerosol Time‐Series

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 1, 16 January 2025.
Abstract The transport and delivery of low‐abundance, bioactive trace elements to the surface ocean by aerosol mineral dust is a major planetary control over marine primary production and hence the global carbon cycle. Variations in the concentration of atmospheric dust have established links to global climate over geologic timescales and to regional ...

Beyond the Average: Computation of Vertical Profiles in Dilute Pyroclastic Density Currents and Their Use in Shallow‐Water Models

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 1, January 2025.
Abstract Pyroclastic density currents (PDCs) present significant hazards due to their high temperatures and dynamic pressures. Accurate estimation of dynamic pressure, vital for assessing potential damage, requires knowledge of the vertical variations of velocity and particle concentration within the PDC, particularly in the first few meters of the ...

Lidar measurements of stratospheric aerosol content and depolarization ratios after the eruption of El Chichón volcano: measurements at Nagoya, Japan

open access: yesGeofísica Internacional, 1984
Después de la erupción de "El Chichón", se observó un enorme aumento en la dispersión de fondo de la luz desde la capa de aerosol estratosférico, utilizando un lidar de rubí en Nagoya, Japón (35ºN, 137ºW).En la parte inferior de la capa principal de ...
