Troposphere, Ionosphere, GPS, and Interferometric Radar (TIGIR) Workshop Proposal; Sepember 21-22, 2009 in Pasadena, CA Grant


  • The PIs will convene a workshop to bring together experts and stake-holders in
    synthetic aperture radar and GNSS systems, the data processing and the products they
    generate. The workshop will examine the wide range of different approaches that have
    been developed to understand and mitigate the atmospheric ?noise? in SAR signals, and
    establish the current best-practices in atmospheric imaging and mitigation techniques,
    generate priorities for further investigations, and recommendations for upcoming
    missions for how best to maximize the utility of the data products they will produce.
    Ionospheric and tropospheric imaging using SAR and GNSS and stochastic and
    deterministic modeling have great potential for correcting media effects on space
    geodetic systems, however, although many of these approaches have shown promise in
    particular circumstances, effectiveness and general applicability are yet to be
    demonstrated. Small amplitude, non-linear and non-periodic ground motion signals
    abound in geodesy from a wide range of sources, and InSAR holds great promise for
    giving us new insights into these types of physical phenomena. For a wide spectrum of
    the signals we might hope to explore, however, the delays induced in the SAR signals by
    the ionosphere and the troposphere overprint and confuse the interpretation of

    This workshop is multi-disciplinary bringing together atmospheric
    and solid earth researchers, operational centers and technologists to find ways to
    understand and mitigate the effects of the atmosphere on new satellite SAR systems.
    Coupled with the compelling hazards research applications of SAR and GPS, this
    workshop provides an excellent venue to engage students. Two students and one career
    researcher will be recruited from a pool of prot_g_s from UNAVCO and UCAR?s
    RESESS and SOARS summer internship program. These two programs have operated in
    partnership for many years providing research opportunities for students from
    underrepresented groups. In addition, a workshop report of the results and outcomes of
    the workshop and statement of recommendations for upcoming SAR missions will be
    generated after the meeting and disseminated via the UNAVCO website.
