Title Proper : AUTOMATED GROUND-BASED METHODOLOGY IN SUPPORT OF VICARIOUS CALIBRATION
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The Remote Sensing Group (RSG) at the University of Arizona performs the vicarious calibrationof airborne and spaceborne sensors using ground-based measurements. Vicarious calibration isimportant because it is independent of the sensor and any onboard calibration system, but itrequires that RSG personnel be present at a test site during the aircraft or satellite overpass. Theground-based data collection can be limited by poor weather, and also by the large traveldistances from RSGبs laboratory to the test sites.This dissertation presents an automated methodology that is used in support of vicariouscalibration. The most important parameter measured during a vicarious calibration field campaignis the surface reflectance, and this work describes the method and instrumentation to obtainsurface reflectance in the absence of RSG personnel. The instrumentation required to measure thesurface and atmospheric parameters is discussed. The design and laboratory characterization of anadir-viewing, multispectral radiometer is presented. Finally, results using this methodology arecompared to those obtained using vicarious calibration, and also with the top-of-atmosphereradiance for one Terra MODIS, and two Aqua MODIS overpasses...tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
