摘要/Abstract

摘要： 针对温度效应会影响太阳光度计观测结果且温度校正系数难以获取等问题, 设计了一种基于热电制冷器 (TEC) 的全自动太阳光度计温控系统。介绍了自研全自动太阳光度计的整体设计，特别是温控系统设计, 并分析了温度对探测器响应的影响。最后对该全自动太阳光度计进行了野外测试, 在合肥地区与商用仪器CE318 进行了同步观测比对, 测试结果表明全自动太阳光度计反演的气溶胶光学厚度与CE318 校正后的结果一致, 偏差在0.01 以内；在敦煌地区的长期测试结果表明, 在温度变化较大的长期野外观测中, 全自动太阳光度计温控系统均保持在 (25 ± 0.2) ℃内, 验证了温控系统设计的有效性和可靠性。

Abstract: According to the problems that the change of temperature can affect the observation results of sun photometer and the temperature correction coefficient is inconvenient to obtain, a temperature control system of automatic sun photometer based on thermo-electric cooler (TEC) was designed. The whole design, especially the temperature control system design, of automatic sun photometer was introduced, and the effect of temperature on detector response was analyzed. The performance of the automatic sun photometer was tested in the field. In Hefei area, China, the automatic sun photometer was compared with the commercial instrument CE318, and the results show that the aerosol optical depth retrieved by the automatic sun photometer is consistent with the corrected result of CE318, with the difference less than 0.01. The long-term test results in Dunhuang area show that the temperature control system of the automatic sun photometer can be kept within (25 ± 0.2) ℃ for long-term field observation with large temperature changes, which verifies the effectiveness and reliability of the system design.

Key words: temperature control, sun photometer, thermos-electric cooling, aerosol optical depth; temperature correction
