Objectives: Spectral and radiometric calibration of radiance-measuring sensors and for quantitative comparison of data acquired from different sites, times and instruments to meet calibration and validation requirements for AVIRIS during the BOREAS experiment. Ground based surface and atmospheric measurements with rigorously calibrated field instruments will be acquired simultaneously with the AVIRIS overflights. With assessments of surface and atmospheric characteristic derived from these ground based measurements a radiative transfer code will be used to predict the total radiance incident at AVIRIS. Analysis using this predicted radiance and the AVIRIS reported radiance will allow validation and calibration of the in-flight spectral and radiometric properties of AVIRIS. Rigorous error analysis of the field measurements, derived parameters, radiative transfer models and sensor characteristics will be implemented to constrain fully the results of this experiment.

The NASA ER-2 carrying AVIRIS
A spectral and radiometric calibration of radiance-measuring sensors such as AVIRIS is required for physically based analysis of the measured data and for quantitative comparison of data acquired from different sites, times and instruments. The data measured in this experiment support this calibration and validation requirement for AVIRIS during the BOREAS experiment. Ground based surface and atmospheric measurements with calibrated field instruments were acquired simultaneously with the AVIRIS overflights.
