The Atmospheric Filter

Volumes I and II

The atmosphere acts like an optical filter that affects visual, infrared, and millimeter wave propagation. The atmospheric filter decreases image contrast and resolution. It reduces measured signal intensity for laser, radar, and non-imaging/radiometer systems. The effects of atmospheric filter sources depend on spectral band and the sensor type used to acquire data. The filter impacts sensor design, data acquisition, and data interpretation.

Engineers and technicians are provided the information necessary to understand and quantify sensor response. Meteorologists are provided guidance on the importance of instrument placement and measurement accuracy when performing remote sensing measurements. Students have access to a wide range of detailed information that supports their early entry into effective experimental design, data acquisition, and remote sensing data analysis.

Numerous approximations are used throughout both volumes. These provide valuable insights into, and a useful working knowledge of, the relationships between meteorology, the atmospheric filter, and remote sensor performance.




" Farmer, a consultant on the effects atmosphere has on the operation and data of remote sensing systems, considers meteorological conditions, background radiation, plume transport and diffusion, transmittance, sky-to-ground ratio, wind, the Pasqul stability. Effects vary according to the spectral band and sensor type being used to acquire data. Of interest to environmental scientists, sensor engineers, and systems analyzers."

"This is the first volume in a two-volume reference concerned with the effects of the atmosphere on the operation and data of remote sensing systems, written for environmental scientists, sensor engineers, and systems analyzers, among others. Farmer, a consultant in the field, covers gases, aerosols, dust, soils, water vapor, refractive turbulence, infrared transmittance, precipitation and fogs, particle measurement, snow, sleet, graupel, and hail."
