联邦航空管理局航空气象研究计划（FAA/AWRP）海洋气象产品开发小组（OW PDT）产生了云顶高度诊断（CTOP），该诊断最近通过航空气象技术转让（AWTT）过程获得了实验状态。该产品创建了一个快速更新的云顶高度视图。特别令人感兴趣的是与湍流、闪电和结冰有关的深对流的发生。然而，CTOP产品还显示了上层卷云，砧云和15，000英尺以下的低云，这可能在飞机受损的罕见情况下构成潜在威胁。在这项研究中，CTOP的性能在两个时期，2004年2月12日至4月23日和8月15日至9月15日，进行了比较，其他云顶高度算法全球可用，包括NESDIS云顶压力（NCTP）产品，NWS雷达回波顶（ET），和云顶高度估计rawinsondes（RCTH）。虽然这些数据源中的每一个都可以推断云顶高度，但是各种方法的比较对于评估CTOP的一致性是有用的。
The Federal Aviation Administration Aviation Weather Research Program (FAA/AWRP) Oceanic Weather Product Development Team (OW PDT) produces a diagnosis of cloud-top heights (CTOP), which has recently received experimental status through the Aviation Weather Technology Transfer (AWTT) process. The product creates a rapidly-updated view of cloud-top heights. Of particular interest is the occurrence of deep convection related to turbulence, lightning, and icing. However, the CTOP product also indicates upper-level cirrus, anvil clouds, and lower clouds down to 15,000 ft, which may potentially pose a threat in the rare situation of a crippled aircraft. In this study, the performance of CTOP during two periods, 12 February – 23 April and 15 August – 15 September 2004, is compared to other cloud-top height algorithms available globally, including the NESDIS Cloud-Top Pressure (NCTP) product, NWS radar echo tops (ET), and cloud-top heights estimated from rawinsondes (RCTH). Although each of these data sources infer cloud-top heights, a comparison of the various approaches is useful to evaluate the consistency of the CTOP.
