collection:
Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer High-Res Data Collection
This collection includes derived Pioneer Venus Orbiter high-resolution ion density data from the OIMS instrument for PVO. It contains it contains sample mass and density data for orbits 1-5055, including data for the period periapsis +/- 30 minutes for each orbit. The collection is divided into multiple files which contain 1 orbit. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Document Collection
This collection contains the document files associated with the Pioneer Venus (PVO) Electron Temperature Probe (OETP) Data Bundle. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) High-Res. Data Collection
This data collection contains derived high resolution number density of electrons (Ne) data, from Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) from 1978-12-05 to 1992-10-07. High resolution measurements are typically available at 2 to 8 second intervals depending upon the telemetry rate available to the OETP at the time. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Bow Shock Data Collection
This data collection contains the orbit-by-orbit times and locations of the bow shock crossings, which are characterized by distinct changes in Ne. Multiple shock crossing are listed if they are sufficiently separated to be resolved accurately. (Bow shock crossings will be evident in the High Resolution Ne File when they occurred within 30 minutes of periapsis) -
bundle:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Data Bundle
This bundle includes PVO Electron Temperature Probe (OETP) collections: High-Res., Low-Res., Ionopause, Bow Shock, Solar EUV, and Browse Plot. -
bundle:
Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer Data Bundle
This bundle includes Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer High-Resolution and Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer Low-Resolution data. -
bundle:
Venus Solar Wind Interactions Data
This bundle contains the data presented in Brecht, S. H. and S. A. Ledvina, An explanation of the nightside ionospheric structure of Venus, JGR, 2020. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Ionopause Data Collection
This data collection contains orbit-by-orbit times and locations of the ionopause crossings, which are evident as sharp gradients in Ne at the top of the ionosphere. (These crossings always occur within 30 minutes of periapsis, so they may be seen in the High Resolution Ne files) -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Browse Plot Collection
This collection contains PDF/A files that contains plots of PVO electron number density data from Venus Orbital Operations. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Solar EUV Data Collection
This data collection contains a file that gives the magnitude of the photoemission current from the radial probe, Ipe, (in units of 10-9 amps) for orbits 0001 to 4800. -
collection:
Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer Document Collection
This collection contains the document files associated with the Pioneer Venus (PVO) Ion Mass Spectrometer Data Bundle. -
collection:
Venus Solar Wind Interactions Data
This collection contains the data presented in Brecht, S. H. and S. A. Ledvina, An explanation of the nightside ionospheric structure of Venus, JGR, 2020. The data is stored in ASCII (text) format for easy reading. Units for the results are in the cgs system, densities (cm^-3), magnetic field (Gauss) and lengths (cm). The magnetic field can be found in the B-GradPe.dat.gz. The O+ density is designated by 2s in the file name. The O2+ density is designated by 3s in the file name. There are 2 types of data files, *.dat.gz and *.sdat.gz. The *.dat files contain the data stored on the Cartesian grid, while the *.sdat contains the data stored on the spherical mesh. -
collection:
Pioneer Venus Orbiter (PVO) Ion Mass Spectrometer Low-Res Data Collection
This collection contains Pioneer Venus Orbiter low-resolution ion number densities data recorded by the Ion Mass Spectrometer (OIMS), from PVO Venus. -
collection:
Pioneer Venus Orbiter (PVO) Electron Temperature Probe (OETP) Low-Res. Data Collection
This data collection includes the Ne, Te and Vs measurements derived by fitting the radial probe voltampere curves taken whenever PVO was within the ionosphere (ie., between the inbound and outbound ionopause crossings). Data from essentially every orbit in 1979 and 1980 included ionosphere transits. -
collection:
Venus Solar Wind Interactions Document Collection
This document collection contains a User Guide file that describes the data in the Venus Solar Wind Interactions Data bundle, which contains the data presented in Brecht, S. H. and S. A. Ledvina, An explanation of the nightside ionospheric structure of Venus, JGR, 2020.
