The University of Colorado simulated the evolution of the twopoint coherence function of a plane wave propagating through globally intermittent turbulence. The specific parameters of the probability-density function used were taken from stratospheric

It is well known that the gas in an ascending helium or hydrogen filled balloon cools faster than the surrounding atmosphere for night ascents. The cooler balloon then removes heat from the surrounding air, resulting in regions of cooler air in the t

Atmospheric effects on normalized stellar irradiance fluctuations for the weak fluctuation regime are examined. Both monochromatic and polychromatic effects are considered. Calculations are performed using a Rytov theory which explicitly includes ref

A Master Data Base was assembled in support of the Airborne Laser Program (ABL). The database consists of two major tables of data, several forms to facilitate data entry and viewing, some queries of the database, and some reports based on the databa

Expressions are summarized for a sample of propagation effects when the refractive index fluctuations deviate from Kolmogorov statistics but are described by a spectrum with a general power law. These effects include a representative amplitude effect

Measurements of atmospheric optical turbulence have been made over the past decade using the thermosonde, a balloon-borne microthermal device that measures the time-averaged temperature differences between two fine wire probes. A probe separation of
