P34A:
Mars Planet-Encircling Dust Event of 2018 II


Submit an Abstract to this Session


Session ID#: 63805

Session Description:
On June 1, a local dust storm moved out of the north circumpolar jet stream in the martian atmosphere, expanding and triggering new dust-raising centers.  By late June, the growing ensemble of storms had become a planet-encircling dust event (PEDE), the first since 2007.  This PEDE was the second earliest such event, just a few days later than the 2001 PEDE.  These events are the major component of interannual-to-decadal variability on Mars and they pose a challenge to solar powered, surface-based flight systems, namely the Opportunity rover and possibly the upcoming InSight lander.  This session solicits observational and modeling presentations related to this year’s PEDE, its onset and decay phase, and its context within the history of such events.  This includes data acquired by observers from the various Mars flight missions and from Earth-based observers, both in orbit and on the ground.
