  author={M. Patrick McCormick and Larry W. Thomason and Charles R. Trepte},
The eruption of Mt Pinatubo in June 1991 caused the largest perturbation this century to the participate content of the stratosphere. The radiative influence of the injected particles put an end to several years of globally warm surface temperatures. At the same time, the combined effect of volcanic particles and anthropogenic reactive chlorine has led to record low levels of stratospheric ozone. 

Study of the Possible Impact of the Calbuco Volcano Eruption on the Abnormal Destruction of Stratospheric Ozone over the Antarctic in Spring 2015

One of the strongest stratospheric ozone depletion events over the Antarctic was observed in October–November 2015. The increase in the ozone hole was associated with the eruption of Calbuco volcano

CLAES observations of Mt. Pinatubo stratospheric aerosol

The UARS CLAES instrument made extensive measurements of the infrared emission of stratospheric aerosol resulting from the June 15, 1991 eruption of Mount Pinatubo from October, 1991 until May, 1993.

A Pinatubo Climate Modeling Investigation

Global cooling of the Earth’s surface has been observed following the largest volcanic eruptions of the past century, although the average cooling is perhaps less than expected from simple energy

A general circulation model (GCM) parameterization of Pinatubo aerosols

The June 1991 volcanic eruption of Mt. Pinatubo is the largest and best documented global climate forcing experiment in recorded history. The time development and geographical dispersion of the

Evolution of HCL concentrations in the lower stratosphere from 1991 to 1996 following the eruption of Mt. Pinatubo

In situ measurements of hydrochloric acid in the lower stratosphere reveal that its mean abundance relative to that of total inorganic chlorine (Cly) has evolved upwards from HCl/Cly = 40% in late


We monitor and model the effects on world-wide temperatures of the June 1991 volcanic eruption of Mount Pinatubo in the Philippines. Global mean air temperatures were reduced, by up to 0·5°C at the

A Temporal Increase in the Atmospheric 210 Pb Concentration Possibly Due to the 1991 Eruption of Pinatubo Volcano: —An Observation at Seoul, the Republic of Korea—@@@―韓国ソウルにおける観測―

A temporal increase in the atmospheric concentration of 210Pb was observed in December, 1991, and January, 1992, at Seoul, the Republic of Korea. This increase was estimated to be due to the fallout

Impact of the Eruption of Mt. Pinatubo on the chemical composition of the tropical atmosphere as simulated with EMAC

The eruption of Mt. Pinatubo on the 12 th June 1991 affected the atmosphere in the tropics (20° S - 20° N) by stratospheric heating and by a change of the heterogeneous chemistry, due to a large

Short-term climatic impact of the 1991 volcanic eruption of Mt. Pinatubo and effects on atmospheric tracers

Large explosive volcanic eruptions are capable of injecting considerable amounts of particles and sulphur gases (mostly sulphur dioxide) above the tropopause, caus- ing increases in the stratospheric

Impact of the eruption of Mt Pinatubo on the chemical composition of the stratosphere

Abstract. This article describes the volcanic effect of the Mt Pinatubo eruption in June 1991 on the ozone ( O3 ) and methane ( CH4 ) distribution in the stratosphere, as simulated with the



Radiative Climate Forcing by the Mount Pinatubo Eruption

Radiative flux anomalies derived from the National Aeronautics and Space Administration (NASA) spaceborne Earth Radiation Budget Experiment were used to determine the volcanic radiative forcing that

Tropical ozone loss following the eruption of Mt. Pinatubo

Total Ozone Mapping Spectrometer (TOMS) measurements of equatorial total ozone following the eruption of Mt. Pinatubo show a decrease of up to 6% over climatology. Ozone losses begin approximately a

Role of sulphur photochemistry in tropical ozone changes after the eruption of Mount Pinatubo

It is found that in the first month or so after the eruption, the large amount of SO2 injected into the tropical atmosphere catalyses mid-stratospheric ozone production, and ozone remains perturbed in the lower stratosphere because of its long photochemical lifetime in this region.

The poleward dispersal of Mount Pinatubo volcanic aerosol

Using the SAGE II 1-μm stratospheric aerosol extinction ratio observations, the dispersal of Mount Pinatubo aerosol within two transport regimes during the first 10 months after the eruption is

Observations of reduced ozone concentrations in the tropical stratosphere after the eruption of Mt. Pinatubo

The eruption of Mt. Pinatubo (15oN, 122oE) on June 15 and 16, 1991, placed a large amount of SO2 and crustal material in the stratosphere. Based on measurements of decreases of stratospheric ozone

Radiatively forced dispersion of the Mt. Pinatubo volcanic cloud and induced temperature perturbations in the stratosphere during the first few months following the eruption

A combined 3-dimensional circulation model and aerosol microphysical/transport model is used to simulate the dispersion of the Mt. Pinatubo volcanic cloud in the stratosphere for the first few months
