High-precision Ground-based Sun / Atmosphere Ultraviolet Spectrum Measurement And Comparison

Ozone vertical distribution probe is one of the aviliable loads of FY-3 satelite. It is an important work to check up its radiance calibrations precision,instrument precision ,statoscope and dynamic rage at the endgame of its meanufacture. So the State Key Laboratory of Applied Optics of Changchun Institute of Optics and Fine Mechanics, Physics carries out a field experiment in Lijiang on Nov and Dec of 2005,cooperating with Center for Space Science and Applied Research Chinese Academy of sciences and China Meteorological Administration, Aational Satellite Meteorological Center. We used the Ozone vertical distribution probe and Ozone total distribution probe to measure the solar ultraviolet radiation at the same conditions. The result of this experiment is very important for the department of satellite administer and the user to evaluate the performance of the two instruments.The performance and the design of Ozone vertical distribution probe is introduced in brief first in chapter two The method of Radiance Calibrations is discussedl in the dissertation. And we design the software for Ozone vertical distribution probe to accomplish Radiance The spectral irradiance response and The spectral radiance response from 250nm to 400nm of the Ozone vertical distribution probe is obtained . Based on this experiment we designed the apparatus for observation-solar tracker .It is a brief design of solar tracker as introduced in this dissertation. And software to control the solar tracker is described in detailed.The result shows that the solar tracker has a high track precision and good delicacy which are necessary for the experiment.Data processing method and the software are discussed in chapter four. The measurement of ultraviolet spectral radiance and ultraviolet spectral irradiance form at 250nm-400nm were done by Ozone vertical distribution probe and Ozone total distribution probe at the same condition. according to the experiment detailed rules. Comparison was done at the same time between the ultraviolet spectral radiance obtained by the two spectral instruments and the results from the OMI instrument on AURO satellite. And the other comparison was also done between the ultraviolet spectral...
