Low-frequency temperature spectra from a 444 meter tower
Review of temperature spectra at three levels in the planetary boundary layer covering a range of periods from about 5 hr to 35 days. Apart from the diurnal and semidiurnal oscillations, there are two identifiable period lengths of interest. One extends from about 3 to 7 days, the other from 7 to 20 days. Comparisons are made between these spectra and those reported by other investigators.
