Recently, the visible-near-infrared spectral irradiance meter and the visible-near-infrared radiance meter developed by the Anhui Institute of Materials Science and Technology, Chinese Academy of Sciences Hefei Institute of Materials Science and Technology, and the two instruments are the projects for the purchase of special funds by the central scientific institutions. The instrument is an important observation instrument for on-orbit performance testing and site calibration of satellite sensors.

The visible-near-infrared spectroradiometer is mainly used for direct observation of the total surface solar irradiance and diffuse irradiance, and can also derive the direct irradiance of the sun. It can also be used for atmospheric optical thickness, atmospheric transmittance, etc. The inversion of parameters provides the necessary basic data for the study of surface and atmospheric optical properties. The irradiance meter is used as a research and development project for the public welfare industry (meteorological) scientific research special radiation correction field and authenticity inspection field equipment and technology. The observation experiment in the calibration field can realize observation of atmospheric optical characteristics of continuously subdivided spectra. The measurement results of the instrument are directly used for radiometric calibration of satellite loads such as FY-3, resource satellites, and NOAA, which is the atmospheric optical characteristics of the radiation correction field. The long-term operational observations of the solar radiation provide technical support, which lays the foundation for equipment conditions for the realization of radiation calibration and authenticity testing with independent intellectual property rights and operationalization. Visible - near-infrared radiance meter is mainly used to observe the target reflectivity, and other equipment such as reference board can also measure the relevant atmospheric optical parameters. The project team introduced that these two instruments are the same commercially available instruments with the widest spectral coverage in the world, and have strong field adaptability to sand and anti-condensation, and three field tests conducted in 2011 and 2012. Fully verified the reliability of the system performance.

In October 2010, the Hefei Research Institute of the Chinese Academy of Sciences and the Chinese Academy of Meteorological Sciences signed a contract to assume the task of developing equipment for the special fund project for the two central-level scientific institutions, and completed development and performance in October 2012. test. At the acceptance meeting, an acceptance panel from the China Meteorological Administration, the Meteorological Exploration Center, the National Satellite Meteorological Center, and the Hefei Research Institute of the Chinese Academy of Sciences believed that the main technical specifications of the two instruments were in line with the requirements of the contract, and that the instrument was field tested and its performance and function were satisfactory. User's use; The documents of acceptance and inspection are complete, and they agree to pass the acceptance check.

The two instruments are project instruments for the purchase of special funds by central scientific institutions. They are important observation instruments for on-orbit performance testing and site calibration of satellite sensors.
