Accurate calibration, analysis, and error assessment provides the foundation for data that can be used to address a range of CEDAR strategic science topics, including coupling in the interaction region between the Earth’s atmosphere and the near space environment, lower-upper atmospheric coupling, Sun-Earth interactions, investigation of atmospheric dynamics through combination of observations such as wind measurements, and long-term climatology observations.


Accurate calibration is important for inter-comparison of observations, data/model comparisons, and long-term investigations. We invite discussion on a broad range of topics relating to passive optical and lidar observations and their analysis. Possible topics include absolute and relative intensity calibration, wavelength calibration, spatial scale determination, error analysis, correction for scattering within the lower atmosphere, isolation of atmospheric lines of interest, flat field techniques, spectral fitting approaches, and analysis of long term data sets. In addition to reporting progress on calibration and analysis techniques, this workshop provides an opportunity to share information on new developments in hardware ( CMOS or CCD detectors, filters, etc.). We encourage hands-on demonstrations. In addition, we welcome modelers to discuss use of observations for model-data comparisons, and associated questions and challenges for model validation. We welcome and encourage presentations by students.

During the second hour, the idea of an "Optics School" will be discuissed. The NSF Aeronomy program has supported various week long focused "schools" for students to learn the basic "nuts and bolts" of Space Weather or Inchoherent Scatter RADARs (ISRs). Perhaps a similar program dealing with issues specific to optical measurements of the atmosphere should be created. We envision a round table discussion of how to proceed with a proposal to NSF to get this process started.
