Many techniques exist for statistically estimating measurement uncertainties in radiometric instruments. One method, the fidelity interval, is addressed here and applied to simulated calibration data for the multi-angle imaging spectroradiometer (MISR). The fidelity interval is the region within which the true radiance is expected to lie with a given probability and thus provides a measure of the calibration uncertainty. Calibration data are reduced using a least- squares approach to provide the gain and offset coefficients used in data reduction. It is from these calibration measurements that the fidelity interval is estimated. The technique allows us to optimize our calibration test plan through simulations which vary the number of radiometric levels, the radiometric range available for testing, and the number of data repetitions.
