Jezero Crater Dust Devil Activity (Perseverance Era)

Perseverance's MEDA meteorology instrument detected hundreds of dust devil passages across its first Martian year of surface operations at Jezero Crater, providing the highest-cadence record of dust devil activity for any Mars landing site to date. Several vortices were captured on camera, and pressure-drop signatures were used to derive vortex diameter and strength statistics. Dust devils at Jezero are more frequent than at InSight's Elysium Planitia site, consistent with Jezero's lower latitude and stronger summer insolation. Dust devil activity is a primary mechanism for lofting dust into the Martian lower atmosphere during non-storm periods.
