Extended Data Fig. 3: Daily cycle temperatures under typical values of thermal inertia and atmosphere’s thermal gradients.
From: The diverse meteorology of Jezero crater over the first 250 sols of Perseverance on Mars
Daily Cycle of temperatures at Jezero under low and high values of TI of the local terrain, and thermal gradients of the atmosphere. (a-c) Low thermal inertia with TI = 260 J·m-2·K-1·s-1/2, as in sols 20-22. (d-f) High thermal inertia terrain with TI = 545 J·m-2·K-1·s-1/2, as in sols 140-150. Colors legend is as in Fig. 2. Low surface thermal inertia (left panels) result in more stable conditions with respect to vertical motions during nighttime than high values of the surface thermal inertia. This is due to the strong locality of surface temperatures, which change strongly in different terrains, compared to a more regular behavior of air temperatures (a and d). The data shown in these figures are the result of averaging the values over 12-minute time intervals, with the standard deviation as the error bar.
