| Data Set Abstract |
In February and March, 1989, the Termoskan instrument on board
the Phobos '88 spacecraft of the USSR acquired a limited set
of very high resolution simultaneous observations of the
reflected solar flux (hereafter referred to as the visible
channel) and emitted thermal flux (thermal infrared (IR)) from
Mars's equatorial region. These are, so far, the highest
spatial resolution thermal data ever obtained for Mars. Four
slightly overlapping thermal panoramas (also called scans or
swaths) cover a large portion of the equatorial region from 30
deg.S to 6 deg.N latitude. Simultaneous visible panoramas were
taken during each of the four observing sessions; due to
spacecraft memory limitations, visible channel processing was
stopped early relative to the thermal channel for 2 of the
sessions (2 and 4). Thus, the visible channel panoramas are
shorter than the thermal panoramas for these sessions. These data
are saved for historical reasons; they are not considered to be
of archival quality. |
