摘 要: | 利用林芝国家基准气侯站冬季(2018年12月-2019年2月),CHP1型太阳直接辐射传感器、DFC2型光电式数字日照计、暗筒式日照计在不同天气模式下的测量值分类进行对比分析。结果表明:三种仪器两两测量值对比绝对偏差和相对偏差,直接辐射传感器测量值在“阴云”、“多云”、“云晴”比暗筒式日照计低,从大到小的顺序为“晴天”>“阴云”>“多云”。DFC2型光电式数字日照计仅“晴天”测量值比暗筒式日照计高,其余则低。从大到小顺序为“晴天”>“多云”>“阴云”;三种设备测量值可以相互替代,取消人工观测设备后,日照资料可以合并使用。

Abstract: | in the winter of linzhi national reference gas station(December 2018-February 2019), the measurement values of the CHP1 solar direct radiation sensor, DFC2 photoelectric digital sunshine meter and dark tube sunshine meter under different weather modes were compared and analyzed. The results show that the measurement values of two kinds of instruments compare the absolute deviation and relative deviation, and the measurement values of direct radiation sensors are lower in "cloudy", "cloudy" and "cloudy" than the dark tube sunshine meter. The order from large to small is "sunny" > "cloudy" > "cloudy". The DFC2 type photoelectric digital sunshine meter is only "sunny" and the measurement value is higher than that of dark tube sunshine, while the rest is low. From large to small, the order is "sunny" > "cloudy" > "cloudy"; The measurements of the three kinds of equipment can be replaced with each other. After the manual observation equipment is cancelled, the sunshine data can be combined. |
