The SHARAD/MARSIS Data Users' Workshop was held on March 16, 2014 (the day before the 45th Lunar and Planetary Science Conference) from 3:00 to 7:00 PM in "Montgomery Ballroom A" at The Woodlands Waterway Marriott Hotel and Convention Center, The Woodlands, Texas.

Hosted by the SHARAD & MARSIS science teams, by the Radar Lab in the DIET Dept. at Sapienza University of Rome, and by the PDS Geosciences Node, the workshop was sponsored by the University of Texas Institute of Geophysics.

Radar sounding data from the SHARAD instrument on the Mars Reconnaissance Orbiter (MRO) and the MARSIS instrument on Mars Express have provided a wealth of information on the near-subsurface of Mars. The goals of the workshop were to:

  • Provide an introduction to the data (radargrams) in both digital and image formats
  • Explain how to locate the data on the planet
  • Explain how to distinguish subsurface returns from surface clutter and how to choose observations that minimize clutter
  • Explain how to convert time-delay results to depth, and to make depth-converted radargrams
  • Discuss ionospheric distortion and strategies for mitigation
  • Discuss various versions of radargrams and where they may be obtained
  • Show how you, too, can process SHARAD data through a user-friendly Web interface
  • Discuss various tools and software packages for mapping subsurface reflectors
  • Explain how you, too, can target SHARAD over your favorite Martian feature
