Summary Report, Atmospheric Propagation, October 1, 1966 to September 30, 1967

Abstract

The report summarizes the work performed during FY 1967. After a brief description of the system and its characteristics, a number of background studies are described. Particular attention has been given to microbarographic pressure fluctuation levels (power spectra) and cross-spectral properties such as coherence and phase lags between pairs of instruments. It is found that an important fraction of the background, in the 5 to 50 min period range, consists of slowly traveling disturbances (20-40 m/sec) probably associated with the jet stream. This part of the background is coherent over distances of a few km, and decorrelates rapidly for distances greater than 10 km. This report also discusses briefly immediate plans for FY 1968.
