本文介绍了用于NOAA国家气候数据中心业务监测和气候评估活动的陆地-海洋表面温度合并分析（MLOST 3.5版）的新版本。最新版本的主要动机是包含了一个新的土地数据集，该数据集有几项重大改进，包括更详细的方法来处理站点位置、仪器和选址条件的变化。新版本与以前的全球分析大致一致，显示出自1901年以来10 - 1年的趋势为0.076°C，自1979年以来10 - 1年的趋势为0.162°C，两个时间段都普遍变暖。总的来说，新版本与前一版本的差异不大，最明显的是在全球尺度上略微变暖（自1901年以来10 - 1年0.004°C），地表的趋势型也略有不同。
This paper describes the new release of the Merged Land–Ocean Surface Temperature analysis (MLOST version 3.5), which is used in operational monitoring and climate assessment activities by the NOAA National Climatic Data Center. The primary motivation for the latest version is the inclusion of a new land dataset that has several major improvements, including a more elaborate approach for addressing changes in station location, instrumentation, and siting conditions. The new version is broadly consistent with previous global analyses, exhibiting a trend of 0.076°C decade−1 since 1901, 0.162°C decade−1 since 1979, and widespread warming in both time periods. In general, the new release exhibits only modest differences with its predecessor, the most obvious being very slightly more warming at the global scale (0.004°C decade−1 since 1901) and slightly different trend patterns over the terrestrial surface.
