FPLUME-1.0: An integral volcanic plume model accounting for ash aggregation [PDF]

open access: yesGeoscientific Model Development, 2016
Eruption source parameters (ESP) characterizing volcanic eruption plumes are crucial inputs for atmospheric tephra dispersal models, used for hazard assessment and risk mitigation. We present FPLUME-1.0, a steady-state 1-D (one-dimensional) cross-section-

35 yr of stratospheric aerosol measurements at Garmisch-Partenkirchen: from Fuego to Eyjafjallajökull, and beyond [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Lidar measurements at Garmisch-Partenkirchen (Germany) have almost continually delivered backscatter coefficients of stratospheric aerosol since 1976. The time series is dominated by signals from the particles injected into or formed in the stratosphere ...

The Red Dawn of Geoengineering: First Step Toward an Effective Governance for Stratospheric Injections [PDF]

open access: yes, 2016
A landmark report by the National Academy of Sciences (NAS) issued in 2015 is the latest in a series of scientific studies to assess the feasibility of geoengineering with stratospheric aerosols to offset anthropogenic global warming and to conclude that

Dynamics and mass balance of El Chichón crater lake, Mexico [PDF]

open access: yesGeofísica Internacional, 2004
The mass balance of El Chichón crater lake is controlled by precipitations, evaporation and seepage through the lake bottom. The main non-meteoric source of water and Cl for the lake is a boiling spring (Soap Pool) discharging saline and neutral water ...

An Overview of the Dynamics of the Volcanic Paroxysmal Explosive Activity, and Related Seismicity, at Andesitic and Dacitic Volcanoes (1960–2010)

open access: yesFrontiers in Earth Science, 2018
Understanding volcanic paroxysmal explosive activity requires the knowledge of many associated processes. An overview of the dynamics of paroxysmal explosive eruptions (PEEs) at andesitic and dacitic volcanoes occurring between 1960 and 2010 is presented

Revisiting the observed surface climate response to large volcanic eruptions [PDF]

open access: yes, 2017
In light of the range in presently available observational, reanalysis and model data, we revisit the surface climate response to large tropical volcanic eruptions from the end of the 19th century until present.

Petrologic characteristics of the 1982 and pre-1982 eruptive products of el Chichon Volcano, Chiapas, México

open access: yesGeofísica Internacional, 1987
Los estudios petrográficos, macroquímicos y por microsonda de una secuencia de rocas del Volcán El Chichón, Chiapas, México, indican que los materiales “juveniles” de las erupciones de 1982 y las anteriores presentan esencialmente la misma química y la ...

Atmosphere Extinction at the ORM on La Palma: A 20 yr Statistical Database Gathered at the Carlsberg Meridian Telescope

open access: yes, 2010
The Observatorio del Roque de los Muchachos (ORM), in the Canary Islands (Spain), was one of the candidates to host the future European Extremely Large Telescope (E-ELT) and is the site of the Gran Telescopio Canarias (GTC), the largest optical infrared ...
