Extended Data Fig. 4: Analysis of thermal oscillations along the sols.
From: The diverse meteorology of Jezero crater over the first 250 sols of Perseverance on Mars
Analysis of thermal oscillations along the sol, for the periods (a) sols 20-22, (b) sols 75-76, (c) sols 140-150, corresponding to different TI values. Blue dots correspond to ATS measurements at z = 0.84 m, green dots to ATS measurements at z = 1.45 m, and yellow dots to TIRS measurements at z ~40 m. The large amplitudes around 20:00 h correspond to thermal contamination by the RTG at that time, as confirmed by simultaneous wind and rover yaw. The oscillations were calculated by detrending the temperature data in each half-hour period using a 2nd order polynomial.
