Reconciling two-component power spectra

Power-law spectra have been used to interpret scintillation data for decades. Twocomponent power-law spectra were invoked to explain observed equatorial scintillation from VHF to S-Band. Carrano and Rino developed new strong-scatter theoretical results described in a companion IES 2015 paper. The new theoretical results have been used to estimate two-component power-law parameters from multi-frequency intensity scintillation data. Although two-component power-law structures have been observed in data from both in-situ rocket and satellite probes, published analyses of C/NOFS high-resolution density data have reported only single power-law characteristics for structure scales greater than 100 m. New results reported in this paper show that two-component power-law spectra are present, but they are con…ned to the most highly disturbed data segments. We reconcile the main body of C/NOFS data with two-component power-law spectra associated with structure strong enough to generate L-band scintillation.
