HadUK-GRID是英国气象局哈德利气候科学和服务中心制作的一个新的格网气候观测数据集。该数据集使用在自2002年以来通过英国气候预测项目(UKCIP02，UKCP09)向用户提供的先前等效数据集中开发的方法，将现场观测数据插入到规则网格中。新的数据集与现有的数据集在一些关键方面有所不同：空间分辨率更高，某些变量的时间序列更长，在台站观测数据的预处理方面的一致性得到了改进，使用了可公开获取的辅助数据源，对一些变量的计算顺序进行了修订，并改进了版本控制。这使得数据集更具内部一致性、更具可追踪性和更具重复性。结果是英国关键气候变量的数据集，分辨率高达1公里，从1862年的月降雨量，1884年的月温度，1891的日降雨量，1929的月日照，以及从20世纪60年代开始的更广泛的变量集，以支持国家气候监测和气候研究的需要。
HadUK-Grid is a new dataset of gridded climate observations for the UK produced by the Met Office Hadley Centre for Climate Science and Services. The dataset interpolates in situ observations to a regular grid using methods developed in a previous equivalent dataset that had been made available to users since 2002 through the UK Climate Projections project (UKCIP02, UKCP09). The new dataset differs from the existing one in a number of key respects: higher spatial resolution, longer time series for some variables, improved consistency with regard to the pre-processing of station observations, the use of publicly-accessible ancillary data sources, a revised calculation sequence for some variables and improved version control. This makes for a dataset that is more internally consistent, more traceable and more reproducible. The result is a dataset of key UK climate variables of up to 1 km resolution from 1862 for monthly rainfall, 1884 for monthly temperature, 1891 for daily rainfall, 1929 for monthly sunshine and a wider set of variables with start dates from the 1960s to support the need for national climate monitoring and climate research.
