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 30S
to 6N 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. |
