Abstract | This paper reports on experimental work to test the feasibility of using reference hyperspectral data sets to carry out vicarious radiometric calibrations for multiple satellite sensors. The methodology
has been validated using data from a campaign at the Railroad Valley playa test site in Nevada. The proof of concept has been further tested based on two data acquisition campaigns at the Newell County rangeland test site in Alberta. All three
campaigns included ground-based measurements, satellite imagery, and airborne hyperspectral data. The airborne image data were acquired using the AVIRIS sensor in Nevada and the casi sensor in all three cases. Radiometric calibration monitoring
results were obtained for six sensors: NOAA-14 AVHRR, Landsat-5 TM, SPOT-1 HRV, SPOT-2 HRV, SPOT-4 VGT, and OrbView-2 SeaWiFS. These results indicate that the nominal on-orbit radiometric calibrations of all the satellite sensors fit within their
predicted uncertainties. The combination of both lower-reflectance and higher-reflectance test sites is shown to improve the quality of the calibration monitoring results. |
