Ionosonde Receiver Signal Amplitude Versus Time Plots


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1963-01-21 to 1964-06-27


This data set, prepared from the ionosonde telemetry tapes at NSSDC, consists of continuous plots of receiver signal amplitude versus time. This data set can be made available on microfilm (16 or 35 mm). The time scale is greatly expanded in comparison to the ionogram so that one ionogram line (16 ms) occupies about 0.5 in. of film record. No amplitude scaling is on the film. In addition to the amplitude records, there are a 1 kHz time signal trace and frequency marker information. Amplitude records for each ionogram require approximately 50 ft of film. Data for a limited number of ionograms were prepared for use in a study of plasma resonance. Additional similar data for other ionograms may be obtained in limited quantity by arrangement with the experiment principal investigator's office as long as original telemetry tapes are on file.
