Tracking climate variables at the levels of precision and accuracy required to detect global change requires satellite sensors to make highly consistent measurements that can be compared to measurements made at different times and with different instruments. Gaps in climate data records, such as those resulting from launch delay or instrument failure, and inconsistencies in radiometric scales between satellites can introduce unnecessary measurement error and thus undermine the credibility of fundamental climate data records. To address these issues, leading experts in satellite remote sensing and lunar observation and modeling assembled at the National Institute of Standards and Technology from 12-15 May 2012 for a workshop to discuss the utility of and strategies for using the Moon to calibrate satellite remote sensing measurements. This report summarizes the outcome of the workshop, including suggested steps to maximize the value of the Moon as an exoatmospheric calibration source for satellite remote sensing.
要以检测全球变化所需的精度和准确度来追踪气候变量，就要求卫星传感器进行高度一致的测量，以便能与在不同时间、使用不同仪器进行的测量相比较。气候数据记录中的缺口，比如由发射延迟或仪器故障导致的缺口，以及卫星之间辐射度尺度的不一致，可能会引入不必要的测量误差，进而损害基本气候数据记录的可信度。为解决这些问题，2012年5月12日至15日，卫星遥感以及月球观测与建模领域的顶尖专家齐聚美国国家标准与技术研究院，参加了一场研讨会，讨论利用月球校准卫星遥感测量的效用和策略。本报告总结了研讨会的成果，包括为将月球作为卫星遥感的外层大气校准源的价值最大化而建议采取的步骤。
