The authors have characterized the near-surface martian wind environment as calculated with a set of numerical simulations carried out with the NASA Ames Mars General Circulation Model (MARS GCM). These wind environments are intended to offer future spacecraft missions to the martian surface a data base from which to choose those locations which meet the mission's criteria for minimal near surface wind to enable a successful landing. The authors became involved in the development and testing of the wind sensor which is currently onboard the Mars-bound Pathfinder lander. The authors began this effort with a comparison of Mars GCM produced winds with those measured by the Viking landers during their descent through the martin atmosphere and their surface wind measurements during the 3+ martian year lifetime of the mission.
