ZCB Plasma structures at 400-850km altitudes in the equatorial ionosphere have been measured by the C/NOFS Planar Langmuir Probe (PLP). This PLP data set contains 1-sec resolution ion number density and its standard deviation, electron density, electron temperature, spacecraft potential, and spacecraft position in geodetic coordinates. As of 5/13/2010, the data were preliminary. the GSFC SPDF Team Pfaff, Robert, F. 2023-01-01T00:00:00 Space Physics Data Facility spase://SMWG/Person/Robert.F.Pfaff GeneralContact spase://SMWG/Person/Lee.Frost.Bargatze MetadataContact C/NOFS PLP 1-s plasma parameter data https://cdaweb.gsfc.nasa.gov/index.html 1-sec PLP avg key parameters preliminary data from CDAWeb spase://VSPO/NumericalData/CNOFS_PLP_PLASMA_1SEC spase://VSPO/NumericalData/CNOFS/PLP/PT1S spase://SMWG/Repository/NASA/GSFC/SPDF/CDAWeb Online Open https://spdx.org/licenses/ SPDX CC0-1.0 https://spdx.org/licenses/CC0-1.0.html Creative Commons Zero v1.0 Universal CC0 1.0 Universal is the Creative Commons license applicable to all publicly available NASA Heliophysics data products CDAWeb https://cdaweb.gsfc.nasa.gov/cgi-bin/eval2.cgi?dataset=CNOFS_PLP_PLASMA_1SEC&index=sp_phys CNOFS_PLP_PLASMA_1SEC Plots, lists and files from CDAWeb.
