Data Set Abstract |
The Electron Reflectometer Data
Record (ERDR) is a time ordered series of electron measurements from the
Mars Global Surveyor (MGS) Mission. Each record consists of a time tag
with 19 scalar data points representing measurements of the electron flux
in 19 different energy channels, ranging from 10 eV to 20 keV, with an
energy resolution of 25%. Each data point is a measure of the electron
flux (cm-2 sec-1 ster-1 eV-1) averaged over a 360 x 14 degree disk-shaped
field of view (FOV). (Parts of this FOV are masked because of spacecraft
obstructions, as described below.) During the Science Phasing Orbits
(SPO), the spacecraft was in Array Normal Spin (ANS) configuration, for
which the ER field of view sweeps out the entire sky (4-pi ster) every
50 minutes, which is much longer than the integration time per record
(2 to 48 sec, depending on energy and telemetry rate) and much longer
than most timescales of interest in Mars' plasma environment. |
