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.
