MARCI weather report, October 8-14, 2018
Dust clouds and hazes continued along the seasonal south polar ice cap edge of Mars this past week. Dust storms were observed from Aonia Terra to northern Noachis Terra to northern Amazonis. The Amazonis storm was advected southwest over the … Continue reading

MARCI weather report, October 1-7, 2018
Weather patterns on Mars were fairly typical last week. Large dust lifting activity associated with the defrosting south polar seasonal ice cap continued over southern Sirenum and Aonia. The western hemisphere of these polar latitudes also had some small dust … Continue reading

MARCI weather report: September 17-23, 2018
During the past week, dusty conditions continued along the retreating seasonal south polar ice cap edge. Sites of activity included Aonia, southern Sirenum, and southwest of Hellas — near the ‘Mountains of Mitchel.’ Looking further northward, dust lifting was relatively … Continue reading

HiRISE: Martian haze
A massive, planet-encircling dust storm occurred on Mars during the summer of 2018, resulting in many images where the surface could not be seen due to the dust. This is a problem for HiRISE but also gives us an exciting … Continue reading

MARCI weather report, September 10-16, 2018
Multiple local-scale dust storms picked up along the seasonal south polar ice cap of Mars this past week. This activity that extended over Aonia, Cimmeria, and near the Mountains of Mitchel generated a diffuse dust cloud along the cap edge. … Continue reading

MARCI weather report, September 3-9, 2018
Slightly hazy conditions continued across many regions of Mars last week. Near the start and end of the week, a couple small dust lifting events occurred over the low-latitudes of Noachis Terra. Looking to the eastern hemisphere, a transient local-scale … Continue reading

MARCI weather report, Aug 27-Sept 2, 2018
Dusty atmospheric conditions resulting from the planetary-encircling dust event continued to wane across much of Mars for the past week. Looking to the equatorial latitudes, a couple short-lived dust events were observed over North Central Noachis Terra. Further west, dust … Continue reading
