Figure 4.32c Range-Velocity-Intensity plots (top) and individual normalized spectra
(bottom) for AMISR-P (left column) and phase velocities at 430MHz on March 12,
2005, observed at the Jicamarca Observatory and theoretically predicted (right column).
Stars and solid squares show data for FB waves moving toward and away from the radar,
respectively. Shaded areas around each data point show the altitude (horizontal scale)
and velocity (vertical scale) uncertainty. Solid and dashed black lines are theoretically
predicted for V ph for 0 and 0
2 aspect angles, respectively. An isothermal ion acoustic
speed is shown as a solid gray line. The dashed gray line denotes the adiabatic process.
