海洋近地表气温在了解当前气候状态方面是一个相对未使用的参数，但作为海洋的独立温度度量是有用的，并作为陆地近地表气温的地理和物理补充。虽然这个数据集有一个完整的版本（HadNMAT 2），但强烈建议各个团体独立生成气候记录，这是这里的一个动机。这项位于亨茨维尔的亚拉巴马大学（UAH）研究首先使用船上的气温构建了从二十世纪初到当今时代的每月夜间海洋气温（UAHNMATv 1）值。使用国际海洋-大气综合数据集3.0版（R3.0）的数据汇编了网格化UAHNMATv 1的完整时间序列。观测需要详细的均匀化程序，因为有许多偏差，如增加船舶高度和改变观测方法。UAHNMATv 1数据集一旦均匀化，就被网格化为1900年至2018年的5.0°月距平。这项研究将呈现量化变化和趋势的结果，并与其他相关数据集的当前趋势进行比较，包括HadNMAT 2和海面温度（HadISST和ERSSTv 4）。这个新的数据集在全球和区域范围内与HadNMAT 2，HadISST和ERSSTv 4数据集具有广泛的总体一致性。
Near‐surface air temperature over the oceans is a relatively unused parameter in understanding the current state of climate, but is useful as an independent temperature metric over the oceans and serves as a geographical and physical complement to near‐surface air temperature over land. Although one complete version of this dataset exists (HadNMAT2), it has been strongly recommended that various groups generate climate records independently, which is one motivation here. This University of Alabama in Huntsville (UAH) study began with the construction of monthly night‐time marine air temperature (UAHNMATv1) values from the early‐twentieth century through to the present era using air temperatures on ships. Data from the International Comprehensive Ocean–Atmosphere Data Set (ICOADS) Release 3.0 (R3.0) were used to compile a complete time series of gridded UAHNMATv1. The observations required detailed homogenization procedures since there are many biases to account for such as increasing ship height and changing observing practices. The UAHNMATv1 dataset, once homogenized, is gridded to 5.0° monthly anomalies from 1900 to 2018. This study will present results which quantify the variability and trends and compare to current trends of other related datasets that include HadNMAT2 and sea‐surface temperatures (HadISST & ERSSTv4). This new dataset has broad overall agreement both globally and regionally with HadNMAT2, HadISST, and ERSSTv4 datasets.
