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 ...

Abstract Stratospheric sulfate aerosols from tropical volcanic eruptions alter surface air temperatures. Fundamentally, this is due to two different properties of the aerosols: Their ability to reflect incoming solar shortwave radiation, and their ability to absorb terrestrial longwave radiation.

A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Abstract The occurrence of sea surface temperature (SST) extremes may provoke profound impacts on ocean health. In the last decade, much effort has been dedicated to understanding and systematically describing marine heatwaves (MHWs) and cold spells (MCSs), defined as prolonged periods of anomalously warm or cold SSTs at a given location, respectively.

On the likelihood of future eruptions in the Chilean Southern Volcanic Zone: interpreting the past century's eruption record based on statistical analyses [PDF]
A sequence of 150 explosive eruptions recorded during the past century at the Chilean Southern Volcanic Zone (SVZ) is subjected to statistical time series analysis. The exponential, Weibull, and log-logistic distribution functions are fit to the eruption

Eruption Column Modeling of Explosive Volcanism on Venus
Abstract Volcanism on Venus has never been directly observed, but several measurements indicate present‐day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle like on Earth. Observation of volcanic activity is the primary objective of future Venus spacecraft. However, there are many unknowns

The Impact of Natural External Forcing on Ocean Heat Uptake Efficiency Since the 1980s
Abstract We investigate the temporal evolution of ocean heat uptake efficiency (OHUE) using observations and large ensemble model simulations. OHUE, defined as the ratio of ocean heat uptake rate to changes in global mean surface temperature anomalies, has exhibited significant variability over recent decades. We found a relatively low OHUE in the late

Impact of Sensible Heating and Water Vapor Emission on Pyro‐Convective Plume Characteristics
Abstract PyroCb events are important sources of stratospheric aerosol. During the Australian forest fires in 2019/2020, such convective plumes transported quantities of smoke into the tropopause region comparable to those of a large volcanic eruption.

Geogenic and atmospheric sources for volatile organic compounds in fumarolic emissions from Mt. Etna and Vulcano Island (Sicily, Italy) [PDF]
In this paper, fluid source(s) and processes controlling the chemical composition of volatile organic compounds (VOCs) in gas discharges from Mt. Etna and Vulcano Island(Sicily, Italy) were investigated. The main composition of the Etnean and Volcano gas

ABSTRACT The June 1991 Mt. Pinatubo eruption resulted in a massive increase of sulfate aerosols in the atmosphere, absorbing radiation and leading to global changes in surface and stratospheric temperatures. A volcanic eruption of this magnitude serves as a natural analog for stratospheric aerosol injection, a proposed solar radiation modification ...
