The primary calibration is that of the temperature sensor used to determine the temperature of the mirror on which frost forms. This is performed by the manufacturer and is traceable to NIST calibrations. The pressure transducer in the housing also affects the derived measrements, but the results are relatively insensitive to uncertainty in this measurement.
The instrument was first flown for testing on the C-130 in 2011, and will be flown again in 2013 on the GV as part of the IDEAS project. These test programs are for initial testing of the performance of the instrument and for deciding if this should be an instrument routinely operated and supported for users. An initial implementation of software code was installed in 2011 and is described in the Technical Note on Processing Algorithms.
