Journal ArticleDOI
The Impact of humidity above stratiform clouds on indirect aerosol climate forcing
TL;DR: In this paper, the authors simulate stratocumulus clouds with a fluid dynamics model that includes detailed treatments of cloud microphysics and radiative transfer, and they show that the response of cloud water to suppression of precipitation from increased droplet concentrations is determined by a competition between moistening from decreased surface precipitation and drying from increased entrainment of overlying air.
Journal ArticleDOI
Smoke and Dust Particles of Meteoric Origin in the Mesosphere and Stratosphere
TL;DR: In this paper, a height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10 to the -16th g/sq cm/s (44 metric tons per day) and the velocity distribution of Southworth and Sekanina, which has a mean of 14.5 km/s.
Journal ArticleDOI
Condensation of HNO3 and HCl in the winter polar stratospheres
TL;DR: In the polar stratospheric clouds, Nitric acid and hydrochloric acid vapors may condense in the winter polar stratosphere as discussed by the authors, and these reactions could deplete the stratosphere of photochemically active NO(x) species.
Journal ArticleDOI
Algorithms for the calculation of scattering by stratified spheres
Owen B. Toon,Thomas P. Ackerman +1 more
TL;DR: Efficient, numerically stable, methods for the calculation of light-scattering intensity functions for concentrically coated spheres are discussed and are accurate for all refractive indices, for large and small particles, and for cores with any relative size.
Journal ArticleDOI
Absorption of visible radiation in atmosphere containing mixtures of absorbing and nonabsorbing particles
Thomas P. Ackerman,Owen B. Toon +1 more
TL;DR: The climatic effects of these absorbing aeorosols are computed using a simple one-layer model, and the results suggest that heating rates in urban pollution layers may be of the order of 4 K/day.
