Magenta asterisks show the determined times of OSS beginning; magenta line represents the evaluated tilt Δf D /ΔT. Figure 3 shows ionograms recorded in Tucumán at the time period in which the OSSs presented in Fig. 1 were recorded.
A spread F, which could be categorized as strong-range spread F (Shi et al. 2011; Alfonsi et al. 2013), was observed at 01 10 UT (Fig. 3b) and at 02 40 UT (Fig. 3d), which are the times in which the OSSs were observed in the Doppler shift spectrogram in Fig. 1.
The application of the unstressed length concept has major advantages both in the simulation (as the OSS can be achieved without any overall iterative process) and in service (as re-tensioning operations to correct time-dependent phenomena effects can be avoided).
From October 1942 to May 1945 he served as chief of the OSS office in Bern, playing, in particular, a notable role in the events that led to the surrender of German troops in northern Italy.
He served in the Jedberg Group of the OSS during W.W. II.
