Roundtable Discussion: How to Define and Include Bias Considerations in
Future OSSEs and Other OSSE topics

  • Potential bias errors from the environment (i.e., atmosphere, scattering,
    WV, spectroscopy, etc.)
  • Potential bias errors from the instrument (i.e., offsets, nonlinearities, orbitor angle-dependent effects)
  • What is the easiest way to adapt our emerging "random error simulation
    capability" to assess these?
  • Dry-Air Mass Calculations
  • What are the appropriate approaches to determine “how small do the bias
    errors need to be” to address the/other different candidate science
    questions? Finally, and importantly, target dates in CY11, to complete
    various aspects of OSSE studies.
