湖州地区FS-RZ1日照传感器试运行分析
|
摘要
为了研究湖州地区试用的FS-RZ1日照传感器跟人工观测数据的差异,利用2018年5月1日～8月31日湖州站和长兴站的FS-RZ1日照传感器数据、德清站直接辐射传感器数据以及上述3个国家级观测站的人工日照数据,分析了日照自动和人工观测的数据差异。结果表明,自动观测日照比人工观测值偏低,自动与人工观测数据的相关性较好,说明误差分布较均匀。具体分析两者每个月的差距变化情况,发现从春天到夏天,两者差距越来越小。早晨和傍晚自动观测的日照时间要大于人工观测,中间时段的人工观测要高于自动。低日照天气总日照时数、人工日照时数均大于自动观测的日照时数。
In order to study the difference between FS-RZ 1-day illumination sensor and manual observation data in Huzhou area. Based on the FS-RZ1 sunshine sensor data of Huzhou Station and Changxing Station, the direct radiation sensor data of Deqing Station and the artificial sunshine data of the three National Observatories mentioned above from May 1 to August 31, 2018, the data differences between automatic and artificial sunshine observations are analyzed. The results show that the automatic sunshine observation is lower than the manual sunshine observation, and the correlation between the automatic sunshine observation and the manual sunshine observation data is better, indicating that the error distribution is more uniform. By analyzing the monthly variation of the gap between the two, it is found that the gap between the two is getting smaller and smaller from spring to summer. The sunshine time of automatic observation in the morning and evening is longer than that of manual observation, and that of manual observation in the middle period is higher than that of automatic observation. The total sunshine hours in low sunshine weather are greater than those observed automatically.
