范围是-10~-90度,在月球上是-180~100度。

Now that we have established the diurnal temperature behavior at the VL1 site, nearby in latitude and longitude, lets take a look at the pathfinder temperature for the sol at the same season from a frame extracted from the Pathfinder page.

The single Viking temperature sensor (black line) in the above plot, which includes Pathfinder Sol 6 data, is located about 1.5 meters above the ground. Pathfinders three sensors are located at 0.25 meter (red), 0.5 meter (green) and 1.0 (blue) meter above the petal, which itself is close to a half meter above the surface on the air bags. These data consist of about three minute averages approximately every 30 minutes throughout the 24.66 hour Martian day. (I chose those colors to represent human associations during daytime, since the sensor closest to the surface is hottest.) Just like on Earth for clear skies and with no front (different air mass) moving in, the vertical temperature gradient reverses at night, with the surface now cooler. Note that with the exception of early morning, the pathfinder temperatures are about 10° C hotter than Viking. This sol clearly shows the transition from stable nighttime (lower sensor cooler) to unstable daytime (upper sensor cooler) at 6 AM and the reverse transition at 18:00, (6 PM).
