Digital Records of Beacon Amplitude Scintillation Due to Solar Wind Turbulence

NSSDCA ID: SPHE-00136

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

Time span: 1968-12-01 to 1973-01-01

Description

These data, written on a magnetic tape in binary format, consist of 79 records for each of two frequencies. Each record covers a 29.75-s time period. Within each record are normally about 900 observations of signal strength received at the spacecraft from the Stanford transmitter. These records were taken over a period of about 4 years, i.e., from an earth-sun-Pioneer-angle (ESPA) of 358 deg around through conjunction (ESPA=360 deg) and occultation (ESPA=180 deg) to ESPA=333 deg. Records are most frequent near occultation (ESPA between 147 and 214 deg). The tape lists digital values of signal intensity (dBm) versus time (measured from the beginning of each record). It also lists derived values used in obtaining spectral analyses of these observations.
