一个新的夜间海洋气温（NMAT）数据集，建立在HadNMAT 2数据集，这是在2013年发布。与HadNMAT 2类似，新的数据集（CLASSnmat）提供了自1880年以来未插值的、分辨率为5°的全球月度数值。除了延长到2019年底外，CLASSnmat还进行了四项主要发展：（1）NMAT值提取自最新版本的国际综合海洋大气数据集（ICOADS Release 3），并采用了消除重复观测的修正方法;（2）除了HadNMAT 2中使用的10 m高度之外，NMAT的值被调整为2 m和20 m高度;（3）对第二次世界大战期间所需的修正进行了改进，它使用了更多的NMAT观测，因此比HadNMAT 2可能的更广泛的空间覆盖范围;（4）使用更新的网格化方法，其允许改进不确定性从各个NMAT值到网格化估计的传播。本文介绍了CLASSnmat（1.0.0.0版）的构造方法。
A new data set of Night Marine Air Temperature (NMAT) is presented that builds on the HadNMAT2 data set, which was released in 2013. In a similar manner to HadNMAT2, the new data set (CLASSnmat) provides uninterpolated, monthly global values at a 5° resolution back to 1880. In addition to being extended to the end of 2019, four main developments are made in CLASSnmat: (1) the NMAT values are extracted from the most recent version of the International Comprehensive Ocean‐Atmosphere Data Set (ICOADS Release 3) and a revised method of eliminating duplicated observations is used; (2) values of NMAT are adjusted to 2m and 20m heights in addition to the 10 m height used in HadNMAT2; (3) a refinement is made to the corrections necessary during World War 2, which uses more of the NMAT observations and hence results in a more extensive spatial coverage for this period than was possible in HadNMAT2; (4) an updated gridding method is used that allows for an improved propagation of uncertainty from the individual NMAT values through to the gridded estimates. In this paper, the method used to construct CLASSnmat (version 1.0.0.0) is described.
