Objectives of the Tuz Golu campaign:
 

• Evaluate differences in field instrument primary calibrations
  • Reference standards used and traceability (based on “Laboratory” information)
  • On-site calibrations/validations
     
• Evaluate differences in methods for characterising and assigning “radiometric value” to a site, for multiple view angles
  • Small area for high-resolution imagers
  • Large area for medium-resolution imagers
     
• Establish formal traceability of Tuz Gölü reference site based on an evaluation of all comparison results.
   
• Establish “best practice” guidance for above and/or knowledge of variance between methodologies.
   
• A multi-sensor (satellite and aircraft) comparison linked to the ground calibration derived from the multi-team comparison.
   
• Identify the minimum and ideal specifications for characterisation/instrumentation for a CEOS “reference standard”
