Abstract: Modelling the atmosphere in accord with recent spacecraft and ground-based observations, we have carried out accurate, multiple scattering calculations to determine the solar energy deposition profile in the atmosphere of ...

Abstract: Not available.

Abstract: We propose an approximate method for evaluating the interaction Of randomly oriented. nonspherical particles with the total intensity component of electromagnetic radiation. When the particle size parameter x (the ratio ...

Abstract: We have computed the perturbation to the infrared radiative heating rates of the lower stratosphere due to the occurrence of polar stratospheric clouds (PSCs) during the winter season in the Antarctic and Arctic regions. ...

Abstract: A global average model of the size distribution, chemical composition and optical thickness of stratospheric and tropospheric aerosols is proposed. The uncertainties involved in making the model are emphasized, and some ...

Abstract: Three?dimensional calculations of the circulation of the Venus atmosphere have resulted in mean zonal winds in the same direction and of the same magnitude as those observed, i.e., retrograde with speeds ?100 m s?1. The ...

Abstract: Calculations of the reflectivity of water clouds (liquid and ice particles) are compared to observations of terrestrial clouds in the near infrared. The presentation is divided into four parts which may be consulted ...

Abstract: A three-layer general circulation model, used to simulate the Martian atmosphere, is described and results are presented. The model assumes a dust-free pure C02 atmosphere and allows for a diurnally- varying convective ...

Abstract: Aircraft and Space Shuttles flying through the stratosphere over the next several decades will add sulfuric acid and aluminum oxide particles, respectively, to this region of the atmosphere. To evaluate the effect of these ...

Abstract: The authors have used the Goddard Institute for Space Studies Climate Model II to simulate the response of the climate system to a spatially and temporally constant forcing by volcanic aerosols having an optical depth of ...
