摘要
为了比较几种自动化测云仪器的性能,中国气象局气象探测中心在南京信息工程大学的 气象探测基地首次组织了一次为期近5个月的比对试验,试验仪器包括四台激光云高仪、 两部红外测云仪、一台全天空成像仪以及一部毫米波云雷达。对其中大部分仪器取得的 三个月云底高度数据进行了初步分析,结果表明:三台激光云高仪测量结果比较一 致;两部红外测云仪在测量低云时一致性稍差;云雷达与激光云高仪测量的最 低层云底高度数据一致性较差,但与红外测云仪的测量结果匹配较好。
Abstract
To compare the consistency of cloud base heights measured by some instruments, the Meteorological Observation Center of China Meteorological Administration firstly organized a nearly 5-month campaign employing four ceilometers, two infrared cloud measuring systems, one Total-Sky-Imager and one cloud radar. The campaign was carried at the observation field within the campus of Nanjing University of Information Sciences & Technology. Preliminary analysis of 3-month cloud base heights obtained from most of the above instruments shows that the data among 3 ceilometers are comparatively consistent, the consistency between the two infrared cloud measuring systems is slightly worse than that from ceilometers, the consistency of observed cloud base height of the first cloud layer between cloud radar and ceilometers is comparatively low, but is much better than that between cloud radar and infrared cloud measuring system.
