摘要: As a part of the pre-flight calibration and validation activities for Ocean Color Temperature Scanner (OCTS) Sea-viewing Wide Field-of-view Sensor (SeaWiFS) ocean color satellite instruments, radiometric measurement comparison was held in February 1995 at NEC Corporation Yokohama, Japan. Researchers from National Institute Standards Technology (NIST), Aeronautics Space Administration/Goddard Flight Center (NASA/GSFC), University Arizona Optical Sciences (UA), Research Laboratory Metrology (NRLM) Tsukuba, Japan used their portable radiometers to measure spectral radiance OCTS visible near-infrared integrating sphere four levels. These levels corresponded configuration when coefficients five eight channels, or bands, instrument were determined. The measurements differed by -2.7 % 3.9 compared overall agreement within combined uncertainties. A participating also resulted results are encouraging demonstrate utility comparisons using laboratory sources. Other will focus on instruments that scheduled spacecraft NASA study climate change, Earth Observing System (EOS).
