Optical calibration facility at the Iza?a Atmospheric Research Center

摘要

During the last years a new optical calibration facility has been developed and deployed at the Iza?aObservatory for the calibration and characterization of the radiation measuring instruments withinresearch activities. These activities require a traceable Quality Assurance & Quality Control system.This new facility allows the absolute, spectral and cosine response calibration. At present there aresix set‐ups running at the laboratory for radiance calibration, angular response determination,spectral response characterization, slit function determination and absolute irradiance calibration(vertical and horizontal set‐ups). Each method and procedure has required the development of thecorresponding protocol. These systems, as well as some examples of instrument calibrations, arepresented in this work.
