| 英文摘要 | The surface reflectance is one of the most critical parameters during a field vicarious calibration. Traditional methods to measure the surface reflectance require personnel at the test site. A ground-viewing radiometer is built to measure the surface reflectance automatically. The radiometer has eight channels in the wavelength range from 400 nm to 1550 nm. The optical system is temperature controlled. A feedback resistor calculation method is introduced that is used to obtain a reasonable signal. Solar radiation-based calibration and two other laboratory methods are used to obtain the absolute calibration coefficients of the radiometer. The average difference in top-of atmosphere spectral radiance is less than 5% between the nine bands of S-NPP and automated vicarious calibration for eight months. The difference of apparent radiance between the results of OLI and automated vicarious calibration is mostly within 5%, therefore, the radiometer works effectively. |
