2.3.2 spase://NASA/NumericalData/POLAR/TIDE/H1_CDF Polar TIDE 6-s Z-unresolved Data 2021-04-27T15:38:11Z The TIDE H1 CDF files contain non-mass Total Ion contribution below 411 eV. Data are available for 1996-12-07 through 2008-04-16. Data is accumulated over the 6-second Polar spacecraft spin. The files contain moments density, velocity (Vx and Vy only), temperature (T_perp and T_para) and the spectrograms for both the differential energy flux versus energy (flux averaged over spin angle) and versus spin angle (flux averaged over energy). Support data includes EFI spacecraft potential (adjusted by +2 volts), magnetic field location, spacecraft ram direction, plotting information, and several parameters that describe the instrument status and details about the data processing. spase://SMWG/Person/Thomas.E.Moore PrincipalInvestigator GeneralContact spase://SMWG/Person/Paul.D.Craven GeneralContact spase://SMWG/Person/Peggy.Sloan MetadataContact spase://VMO/NumericalData/POLAR/TIDE/H1_CDF spase://VSPO/NumericalData/POLAR/TIDE/H1_CDF spase://SMWG/Repository/NASA/GSFC/SPDF Online Open CDAWeb https://cdaweb.gsfc.nasa.gov/cgi-bin/eval2.cgi?dataset=PO_H1_TID&index=sp_phys PO_H1_TID CDAWeb TIDE H1 CDF viewer FTPS from SPDF (not with most browsers) ftps://spdf.gsfc.nasa.gov/pub/data/polar/tide/tide_h1/ CDAWeb TIDE H1 CDF viewer HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/data/polar/tide/tide_h1/ In CDF via HTTP from SPDF CDF spase://SMWG/Repository/NASA/GSFC/SPDF Online Open CDAWeb HAPI Server https://cdaweb.gsfc.nasa.gov/hapi PO_H1_TID Web Service to this product using the HAPI interface.

The detection of time-of-flight direct-events deteriorated rapidly early in the mission, reducing the ability to resolve ion masses and resulting in the lost of information in one axis (Z). After 09/30/96, the ion data is of poor quality and as a result, only Total Ions (Stops) are reported starting 12/08/96. Total Ions is the sum over the 7 polar angle channels of the particle counts detected by the Stop microchannel plate (MCP) detectors. The resolution in the 32 energy steps and in the 32 spin angle bins is retained. 1996 H+, O+, and He+ data are reported in the TIDE H0 CDFs. In order to avoid damage to the MCPs, starting 03/27/96 and continuing throughout the rest of the mission, the high voltage on the MCPs is reduced during radiation belt passes.
