Abstract: Various positive and negative ionic processes of importance in controlling the electron density in the lower ionosphere are discussed. In particular, models of the effective dissociative recombination coefficient based on ...

Abstract: An investigation was made of the effect of amines, ammonia, and alcohols on the nucleation of super-cooled water droplets by silver-iodide crystals. It was found that they inhibit the nucleation and that the vapor ...

Abstract: Free chlorine atoms produced from HCl deposited by solid-fueled rocket engines react to destroy odd oxygen in the stratosphere. Using a one-dimensional photochemical model, we have computed the reduction of ozone likely ...

Abstract: We have estimated the potential effects on stratospheric aerosols of supersonic transport emissions of sulfur dioxide gas and submicron soot granules, and space shuttle rocket emissions of aluminum oxide particulates. ...
