RISImproved Normalization of the Size Distribution of Atmospheric Particles Retrieved from Aureole Measurements Using the Diffraction Approximation
Publisher: American Meteorological Society
Abstract: his paper describes an improvement in the diffraction approximation used to retrieve the size distribution of atmospheric particles from solar aureole radiance measurements. Normalization using total optical thickness based ...
The Truncated Geometric Approximation and the Size Distribution of Small Atmospheric Particles
Publisher: American Meteorological Society
Abstract: his paper describes a simple relationship between the slope of particulate optical depth as a function of wavelength and the size distribution of spherical particles. It is based on approximating extinction using a truncated ...
The Semidiurnal Atmospheric Tide at the Equinoxes: A Spectral Study with Mean-Wind-Related Influences and Improved Heating Rates
Publisher: American Meteorological Society
Abstract: Calculations of the semidiurnal atmospheric tide at the equinoxes using improved heating rates and realistic mean winds and temperatures are presented. The heating rates for equinox are quite similar to those reported by ...
Influence of Mean Zonal Motion and Meridional Temperature Gradients on the Solar Semidiurnal Atmospheric Tide: A Revised Spectral Study with Improved Heating Rates
Publisher: American Meteorological Society
Abstract: Calculations of the semidiurnal atmospheric tide at solstice using improved heating rates are presented. The heating rates for solar absorption by water vapor are based on a global water vapor distribution (Jenne, 1969, ...
Retrieving Properties of Thin Clouds from Solar Aureole Measurements
Publisher: American Meteorological Society
Abstract: This paper describes a newly designed Sun and Aureole Measurement (SAM) aureolegraph and the first results obtained with this instrument. SAM measurements of solar aureoles produced by cirrus and cumulus clouds were taken ...
