Abstract
In order to realize the quantitative application of satellite remote sensing data and adapt to the demand of field calibration of hyper-spectral remote sensors, the solar direct spectral irradiance-meter was developed. According to the sampling principle of spectral irradiance, the irradiance-meter was designed with some technical improvements, the radiometric calibration based on system-level detector were adopted. Irradiance-meter took part in field calibration experiment on Dunhuang radiometric calibration sites and the correct data results were collected. The measurement results of spectral irradiance were consistent with simulated ground irradiance by MODTRAN model. The relative deviation of atmospheric optical depth(AOD) compared with solar radiometer CE318 was less than 4.84%. The whole day results of the irradiance observations and atmospheric transmission in the data applications were collected, the local atmosphere mode and the change of environment were reflected accurately, the input information of the atmospheric parameter were provided for the study of atmospheric properties and field calibration of remote sensors.
