Incorporation of mineralogical composition into models of the radiative properties of mineral aerosol from UV to IR wavelengths
We describe a technique to model the radiative properties of mineral aerosols which accounts for their composition. We compile a data set of refractive indices of major minerals and employ it, alongExpand
The impact of humidity above stratiform clouds on indirect aerosol climate forcing
Simulation of stratocumulus clouds with a fluid dynamics model shows 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.

Rapid calculation of radiative heating rates and photodissociation rates in inhomogeneous multiple scattering atmospheres
The solution of the generalized two-stream approximation for radiative transfer in homogeneous multiple scattering atmospheres is extended to vertically inhomogeneous atmospheres in a manner which isExpand
The optical constants of several atmospheric aerosol species: Ammonium sulfate, aluminum oxide, and sodium chloride
The optical constants of substances composing atmospheric aerosols are required to evaluate properly the effects of aerosols on the earth's radiation balance. We briefly review techniques forExpand
Smoke and Dust Particles of Meteoric Origin in the Mesosphere and Stratosphere
Abstract A height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10−16 g cm−2 s−1 (44 metric tons per day) and the velocity distribution of Southworth and Sekanina,Expand
Direct radiative forcing by anthropogenic airborne mineral aerosols
AIRBORNE mineral dust can have a significant effect on the Earth's radiation budget, as it can both scatter sunlight back to space (leading to negative radiative forcing), and absorb solar andExpand
Absorption of visible radiation in atmosphere containing mixtures of absorbing and nonabsorbing particles.
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. Expand
A Hydrogen-Rich Early Earth Atmosphere
The organic soup in the oceans and ponds on early Earth would have been a more favorable place for the origin of life than previously thought. Expand
Hydrodynamic escape is an important process in the formation and evolution of planetary atmospheres. Transonic steady state solutions of the time-independent hydrodynamic equations are difficult toExpand
A multidimensional model for aerosols - Description of computational analogs
The numerical algorithms used to simulate the advection, diffusion, sedimentation, coagulation and condensational growth of atmospheric aerosols are described and the continuity equation is developed in a generalized horizontal and vertical coordinate system. Expand
