Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

open access: yes, 2011
Explosive volcanism affects weather and climate. Primary volcanic ash particles which act as ice nuclei (IN) can modify the phase and properties of cold tropospheric clouds.

Monitoring diffuse volcanic degassing with seismic ambient noise [PDF]

open access: yesNatural Hazards and Earth System Sciences
Diffuse volcanic degassing is a persistent and often underestimated natural hazard, with potential impacts on air quality, ecosystem health, and volcanic risk management.

A regional climate palaeosimulation for Europe in the period 1500–1990 – Part 1: Model validation [PDF]

open access: yesClimate of the Past, 2013
We present and analyse a high-resolution regional climate palaeosimulation encompassing the European region for the period 1500–1990. We use the regional model MM5 driven at the boundaries by the global model ECHO-G.

Strong responses of Southern Ocean phytoplankton communities to volcanic ash [PDF]

open access: yes, 2014
Volcanic eruptions have been hypothesized as an iron supply mechanism for phytoplankton blooms; however, little direct evidence of stimulatory responses has been obtained in the field.

Timing and climate forcing of volcanic eruptions for the past 2,500 years [PDF]

open access: yesNature, 2015
Volcanic eruptions contribute to climate variability, but quantifying these contributions has been limited by inconsistencies in the timing of atmospheric volcanic aerosol loading determined from ice cores and subsequent cooling from climate proxies such as tree rings.

Stratospheric age of air variations between 1600 and 2100

open access: yesGeophysical Research Letters, 2016
The current understanding of preindustrial stratospheric age of air (AoA), its variability, and the potential natural forcing imprint on AoA is very limited.

Four-dimensional distribution of the 2010 Eyjafjallajökull volcanic cloud over Europe observed by EARLINET [PDF]

open access: yes, 2012
The eruption of the Icelandic volcano Eyjafjallajökull in April–May 2010 represents a "natural experiment" to study the impact of volcanic emissions on a continental scale.

Volcanic forcing of the Lomagundi–Jatuli carbon isotope excursion [PDF]

open access: yesProceedings of the National Academy of Sciences
The Lomagundi–Jatuli Event (LJE), Earth’s most pronounced and prolonged positive carbon isotope excursion, followed the Great Oxidation Event and remains enigmatic in origin. We present a Pb–Pb isochron age of 2,194 ± 5 Ma for black shales from the Francevillian FB Formation, Gabon—an LJE type locality—coinciding with the ...

The Detection and Attribution Model Intercomparison Project (DAMIP v1.0) contribution to CMIP6 [PDF]

open access: yesGeoscientific Model Development, 2016
Detection and attribution (D&A) simulations were important components of CMIP5 and underpinned the climate change detection and attribution assessments of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. The primary goals

Charge structure in volcanic plumes: a comparison of plume properties predicted by an integral plume model to observations of volcanic lightning during the 2010 eruption of Eyjafjallajökull, Iceland [PDF]

open access: yes, 2014
Observations of volcanic lightning made using a lightning mapping array during the 2010 eruption of Eyjafjallajökull allow the trajectory and growth of the volcanic plume to be determined.
