Abstract
This is an interim report of an ongoing CAL/VAL study for the ADEOS AVNIR sensor which is being conducted by the ADEOS sensor team and working group (including PIs). In order to calibrate and validate on-orbit AVNIR sensor characteristics, ADEOS CAL/VAL Campaign experiments using AVIRIS were conducted in the western USA. AVIRIS observations from ER-2 aircraft correlative flights by NASA JPL were conducted over Rogers Dry Lake and Ivanpah Playa in California on February 28 and March 4, 1997 respectively. The Japanese AVNIR sensor team/WG and NASA JPL team successfully performed correlative field experiments in both test sites.
This paper firstly describes the objectives and outline of these ADEOS CAL/VAL campaign experiment in the USA. A few of in-situ simultaneous measurements data using spectral radiometers, Sun photometers, sky radiometer etc. are then shown. Finally, the first results of preliminary analysis for these field experiments are presented. Estimated gain parameters of AVNIR Mu bands are presented for Ivanpah Playa and Rogers Dry Lake using a vicarious calibration method. Typical estimated values of PSF1/2 of AVNIR Mu bands without atmospheric correction are also presented. As the CAL/VAL study for the AVNIR sensor is still ongoing, these data are tentative and must be validated.
