This data set consists of hourly resolution data in ASCII format from the Pioneer 11 Plasma Analyzer. It contains five types of data: 'REDR' and EDR data, Spectral' data, 'summary' (high resolution) parameter data, hourly averaged parameter data, and trajectory data. The plasma bulk parameters (bulk velocity, proton number density, proton temperature, and flow angles) were obtained using one of three processing schemes described in the data set documentation. Hourly averaged data files were created by averaging every valid parameter in each hour, regardless of the processing scheme used to derive it. Each plasma data file contains a header followed by data records. The filename format is p10_XX_YYh.asc where XX and YY are the start and end years of data in the file. Each data record contains the spacecraft ID (SCID), year, day of year, and time of day in hours, followed by the bulk velocity, number density, temperature, and where appropriate, the flow angles. Speeds are given in km/s, number densities are given in #/cc, temperatures are given in K, and flow angles are given in degrees. Prior to day Jan. 31, 1989, all directions are given in a spacecraft-centered ecliptic system, in which the E/W angle is positive in the direction of planetary rotation while a N/S angle of zero means that the solar wind flow is parallel to the plane of the ecliptic. After Jan. 31, 1989 the flow directions are given with respect to a RTN heliographic system for which the R component is radially outward from the Sun, T is in the direction of planetary orbital motion around the Sun, and N is orthogonal (RxT) to R and T. |

Resource ID:spase://VSPO/NumericalData/Pioneer_Venus/MAG/PT1H | ||||||||||||||||||

| ||||||||||||||||||

This data set includes hourly averages of the interplanetary magnetic field magnitude and vector components measured by the Pioneer Venus Orbiter. The magnetic field data and spacecraft coordinates are provided in the Venus Solar Observer (VSO) system. Data collection periods inside the Venusian bow shock have been removed and hour averages have computed for those data points. Note that the BT values are computed from magnitudes of high resolution (1/4 sec.) vectors and are actually overlapped two-hour averages computed every hour to avoid potential aliasing effects from non-overlapping averages. The vector component averages are also overlapped in the same manner. Also note that BT will generally be higher than the magnitude of the hour-average field vector, so the latter should not be used to compute magnitude. Data records for hours 8-10 of July 3, 1979 have been removed since the data values are erroneous. Two-minute overlapping averages without the bow shock cuts were previously archived at NSSDC as dataset 78-051A-12G for data from 1978-12-06 through 1984-09-30 (this data set now extends through 1992-10-08, the end of the PVO mission). Detailed questions on the removal procedure should be directed to Chris Russell. This data was supplied by Janet Luhmann (now at UC-Berkeley) and Muriel Kniffen of the UCLA PVO magnetometer team in support of PVO data archiving and the COHO program. A transformed version of this data set in heliographic & RTN coordinates may be found in COHO directory PIONEER_VENUS/MERGED and can also be plotted on-line using the COHOWeb system. |

This data set holds hourly data for the interplanetary solar wind near Venus from the Plasma Analyzer (OPA) experiment on the Pioneer Venus Orbiter spacecraft. Data coverage includes cruise (enroute to Venus from Earth, May - Dec. 1978) and orbital (Dec. 1978 to Oct. 1992) mission phases up through loss of telemetry on Oct. 8, 1992 before atmospheric entry. The data consist of hourly-averages of the derived plasma parameters for every spectrum returned by the OPA. Each record consists of the spacecraft ID, the date of the record, the hour of the day (spacecraft event time) at the start of the record, reserved (but not used) space for the magnetic field and its azimuthal and polar angles, the proton temperature (K), and the plasma density (cm-3), bulk speed (km/sec), and azimuthal and polar flow angles (degrees). Also included in each record is the RMS dispersion of the derived, averaged quantities. Measurements made inside the Venusian bow shock were mostly excluded. The ASCII hourly data here are described in plain text files (*.txt). Orbital data in heliocentric or Venus-centered coordinates are provided with both datatypes. The hourly data may also be browsed, plotted, and retrieved through the COHOWeb data system. Merged solar wind magnetic field and plasma data from PVO, transformed into more convenient heliographic/RTN coordinates, are available in COHO directory PIONEER_VENUS/MERGED. |
