Name
TIDE H1 CDF
Description

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.

Caveats

TIDE was originally designed to detect mass-resolved ions, H+, O+, He+, and NO+, for 32 energy steps (31 reported), 32 spin angle bins, and 7 polar angle channels. 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.

Name
Thermal Ion Dynamics Experiment (TIDE)
Alternate name
TIDE
Description

This investigation, TIDE (thermal ion dynamics experiment), is designed to study the origin, transport, energization, storage, and loss of low energy ions in the earth's magnetosphere. The instrument measures the distribution function of ions in the energy range 0-100 eV and the mass range 1 to 16 u. A complete ion distribution is obtained over each spin of the spacecraft (nominally 6 s). The instrument consists of two sensor assemblies and an electronics assembly. The two sensors are mounted on opposite edges of the spacecraft, and each has a field of view of 170 deg. Control of the instrument by an onboard microprocessor permits programmable sequences of angle, energy, and mass to be selected for specific studies. The angular acceptance is in 10 x 10 deg windows covering a 120-deg fan in the plane containing the spin axis, and in 2- x 2-deg windows on 4-deg centers covering a 30-deg fan in the plane containing the spin axis. Energy resolution is nominally 20%, and mass resolution is 25% for masses 1-4 u, 8% for masses 4-16 u, and 3% for masses 16-64 u.

GGS/Polar
ISTP/Polar
Description

POLAR is one of four spacecraft in the Global Geospace Science (GGS) program. These are among the six spacecraft in the International Solar Terrestrial Physics (ISTP) program. POLAR provides multi-wavelength imaging of the aurora, measuring plasma entry into the polar magnetosphere and geomagnetic tail, the flow of plasmas to and from the ionosphere, and the deposition of particle energy in the ionosphere and upper atmosphere. POLAR has on-board propulsion systems and a design lifetime of three to five years, with redundant subsystems. POLAR is cylindrical, approximately 2.8 m in diameter by 1.25 m high (plus 1.25 m for its two despun platforms), with body-mounted solar cells, weighs 1250 kg and uses 333 W of power. The spin rate is 10 rpm around an axis approximately normal to the orbital plane. It has long wire spin-plane antennas, inertial booms, and spin-plane appendages to support sensors. POLAR has two despun gimbaled instrument platforms, and booms are deployed along both Z axes. Data are stored using on-board tape recorders and are relayed to the Deep Space Network at 600 kbps maximum (250 kbps nominal) although the average real-time data rate for POLAR is 41.6 kbps. POLAR has a 22.6-h polar orbit (90 deg inclination), with perigee and apogee of 11,500 and 57,000 km. Polar was launched to observe the polar magnetosphere and, as its orbit has precessed with time, has observed the equatorial inner magnetosphere and is now carrying out an extended period of southern hemisphere coverage. Details on the POLAR mission and instrumentation are provided in Space Science Reviews (Vol. 71, Nos. 1-4, 1995) and reprinted in The Global Geospace Mission, edited by C. T. Russell (Kluwer, 1995).

TIDE Data Archive

The TIDE Data Archive contains all TIDE data and plot files. The files can most easily be accessed through the appropriate links on the TIDE website but they can be accessed directly. See http://tide.gsfc.nasa.gov/data_archive_desc.shtml for the location of the files used in the TIDE level-zero processing software (level-zero, orbit, attitude, mask, and spacecraft potential) and the location of the spectrogram summary plot files (gif, jpeg, and pdf). The archive contains copies of the TIDE H1and H0 CDF files (also available at the CDAWeb). Documentation, software, and miscellaneous files are also kept on the archive.
