Fourth FORMOSAT-3/COSMIC Data Users Workshop

27 - 29 October 2009
Boulder, Colorado U.S.A

FORMOSAT-3/COSMIC (F3C) is a joint Taiwan/US science mission for weather, climate, space weather and geodetic research. The F3C mission was successfully launched on 15 April 2006. Six identical micro satellites, each carrying an advanced GPS radio occultation (RO) receiver, a Tiny Ionospheric Photometer (TIP) and a Tri Band Beacon (TBB) were deployed. The satellites have since been raised by Taiwan's National Space Organization (NSPO) to their final orbit altitude at 800km to achieve an operational constellation of six orbital planes separated by 30 degrees. The payload science data are currently being downloaded every orbit via two NOAA TT&C stations (in Alaska and Norway) and one NSF/NASA station in McMurdo, Antarctica and transferred to the COSMIC Data Analysis and Archival Center (CDAAC) at UCAR in Boulder. The CDAAC currently processes the COSMIC science data in near real time - 90 percent of RO profiles are delivered to operational weather centers within 3 hours of observation. CDAAC also reprocesses data in a more accurate post-processed mode (within 6 weeks of observation) for COSMIC as well as other missions including GPS/MET, CHAMP, SAC-C, and GRACE.

COSMIC is currently providing between 1000-2500 daily RO profiles in the neutral atmosphere, 1000-2500 daily electron density profiles and total electron content arcs, and TIP radiance products. The data have already demonstrated their value for operational weather forecasting, hurricane forecasting, and investigations of the atmospheric boundary layer. The data have been used extensively to test ionospheric models and their use in operational space weather models is under development. COSMIC GPS RO data also have the potential to be of great benefit to climate studies due to their demonstrated high precision and global and diurnal sampling coverage.

Workshop objectives:

  • Dialogue between data providers and data users
  • Update the user community on the status of the mission
  • Status of CDAAC data processing and data availability
  • Scientific investigations with COSMIC data
  • Results obtained with GPS, TIP and TBB data
  • Data validation experiments
  • Comparison with other sensors - including other RO missions (CHAMP, SAC-C, GRACE, TerraSAR-X, METOP/GRAS, TechSat-21)
  • Status of Precise Orbit Determination and Excess Atmospheric Phase Processing - Algorithm improvements and validation studies
  • GPS RO retrieval improvements
  • Data assimilation into numerical models - Impact studies from NCEP, ECMWF, UKMO and other leading weather centers
  • Climate studies with RO data
  • Use of the data in ionospheric models - early operational tests
  • Future plans for validation experiments, campaigns, or other projects in the neutral atmosphere and ionosphere
  • Discussions related to COSMIC-II Follow-On mission

We invite participants that have used or plan to use data from the F3C mission to contribute presentations or posters to this workshop. The success of the mission depends on broad participation from the science community. By March 2009 we have > 1000 registered F3C data users and we are looking forward to understanding their uses of the data and to feedback that will help us improve the CDAAC data products.
