Above is shown the DERIVED NEAR-SURFACE ATMOSPHERIC TEMPERATURES and SURFACE PRESSURE values during Session #1030 from the Mars Pathfinder Meteorology (MET) Instrument Package. This session was 89052 seconds in duration, starting at ~6 AM on Sol 25 of the mission, with a sampling rate of 0.25 Hz (producing 22262 measurements) . Session lengths ranged from 152 to 89052 seconds; there were a total of 1430 sessions through the duration of the mission.
The MET Instrument Package included three thermocouples attached near the Top, the Middle, and the Bottom of the MET Mast (plus a fourth thermocouple, the Descent thermocouple, located a bit below the height of the Top thermocouple). The MET Package also included a pressure sensor and wind speed and direction sensor (wind data are not shown above).
All of the variables mentioned for the figure above: the derived thermocouple temperatures, the derived pressure, and the derived wind sensor signals (temperatures), are provided within the sr1030s.tab ASCII file located within the sr13xxs folder which itself is within the scidata folder within the surf_rdr folder of the Mars Pathfinder Lander Meteorology data archive mpam_0001.
