Abstract: A spectral three-dimensional model of the stratosphere is used to investigate the possible dynamical effects in the stratosphere of the aerosol cloud formed after the eruption of Mt. Pinatubo. A non-negligible perturbation ...

Abstract: A simple scheme is proposed to account for the Rayleigh scattering effects on photodissociation rates. The method is based on combining the reflectivity and transmission effects of two layers?one above and one below the ...

Abstract: A two-dimensional model has been integrated for two years to study the evolution of the El Chichón aerosol cloud in the stratosphere, starting about three months after the eruption. Initial conditions for the backscattering ...

Abstract: The determination of an accurate quantitative understanding of the role of tropospheric aerosols in the earth's radiation budget is extremely important because forcing by anthropogenic aerosols presently represents one of ...
