Spatial and temporal variability of the stratospheric aerosol cloud produced by the 1991 Mount Pinatubo eruption
[1] As a critical quality control step toward producing a stratospheric data assimilation system for volcanic aerosols, we conducted a comparison between Stratosphere Aerosol and Gas Experiment (SAGE) II aerosol extinction profiles and aerosol backscatter measured by five lidars, both in the tropics and midlatitudes, for the two-year period following the 1991 Mt. Pinatubo eruption. The period w...
متن کاملHarmonic Excitation of Mantle Raleigh Waves by the 1991 Eruption of Mount Pinatubo, Philippines
An unusually long (at least two hours) seismic wave train having periods of about 230 sec was recorded at many worldwide seismic stations during the major eruption of Mount Pinatubo in the Philippines on June 15, 1991. This wave train exhibits two sharp spectral peaks at 228 and 270 sec. The group velocity, phase velocity, and the particle motion of this wave train indicate that it is a Rayleig...
متن کاملSouthern Hemisphere Atmospheric Circulation Effects of the 1991 Mount Pinatubo Eruption
1 Global average cooling and Northern Hemisphere winter warming are well-known 2 climatic responses to the June 15, 1991 eruption of the Mount Pinatubo volcano in the 3 Philippines. Here we investigate the Southern Hemisphere response. Using National Centers for 4 Environmental Prediction/National Center for Atmospheric Research Reanalysis, European 5 Centre for Medium-Range Weather Forecasting...
متن کاملRe-evaluation of SO2 release of the 15 June 1991 Pinatubo eruption using ultraviolet and infrared satellite sensors
[1] In this study, ultraviolet TOMS (Total Ozone Mapping Spectrometer) satellite data for SO2 are reevaluated for the first 15 days following the 15 June 1991 Pinatubo eruption to reflect new data retrieval and reduction methods. Infrared satellite SO2 data from the TOVS/HIRS/2 (TIROS (Television Infrared Observation Satellite) Optical Vertical Sounder/High Resolution Infrared Radiation Sounder...
متن کاملClimate forcing by the volcanic eruption of Mount Pinatubo
[1] We determine the volcano climate sensitivity l and response time t for the Mount Pinatubo eruption, using observational measurements of the temperature anomalies of the lower troposphere, measurements of the long wave outgoing radiation, and the aerosol optical density. Using standard linear response theory we find l = 0.15 ± 0.06 K/(W/m), which implies a negative feedback of 1.4 (+0.7, 1.6...
