HadUK-Grid Climate Observations by UK river basins, v1.0.2.1 (1862-2019)

HadUK-Grid is a collection of gridded climate variables derived from the network of UK land surface observations. The data have been interpolated from meteorological station data onto a uniform grid to provide complete and consistent coverage across the UK. These data at 1 km resolution have been averaged across a set of discrete geographies defining UK river basins consistent with data from UKCP18 climate projections. The dataset spans the period from 1862 to 2019, but the start time is dependent on climate variable and temporal resolution.

The gridded data are produced for daily, monthly, seasonal and annual timescales, as well as long term averages for a set of climatological reference periods. Variables include air temperature (maximum, minimum and mean), precipitation, sunshine, mean sea level pressure, wind speed, relative humidity, vapour pressure, days of snow lying, and days of ground frost.

This data set supersedes the previous versions of this dataset which also superseded UKCP09 gridded observations. Subsequent versions may be released in due course and will follow the version numbering as outlined by Hollis et al. (2018, see linked documentation).

For this version of note is that historical data recovery has improved monthly rainfall 1862-1910, daily rainfall 1883-1910, monthly temperature 1900-1909, and additional sunshine grids for 1919-1928 have been added.

The primary purpose of these data are to facilitate monitoring of UK climate and research into climate change, impacts and adaptation. The datasets have been created by the Met Office with financial support from the Department for Business, Energy and Industrial Strategy (BEIS) and Department for Environment, Food and Rural Affairs (DEFRA) in order to support the Public Weather Service Customer Group (PWSCG), the Hadley Centre Climate Programme, and the UK Climate Projections (UKCP18) project. The data recovery activity to supplement 19th and early 20th Century data availability has also been funded by the Natural Environment Research Council (NERC grant ref: NE/L01016X/1) project "Analysis of historic drought and water scarcity in the UK". The dataset is provided under Open Government Licence.

HadUK-Grid系由英国陆地观测网络中提取的格网化气候变量构成的集合。该数据集通过气象站数据插值至统一网格，旨在为英国提供全面且一致的覆盖。以1公里分辨率的这些数据，已根据与UKCP18气候预测数据一致的定义，对英国河流流域的一系列离散地理区域进行了平均。该数据集覆盖了1862年至2019年的时期，但起始时间取决于气候变量和时间分辨率。

格网数据按日、月、季节和年度时间尺度生产，同时还包括一系列气候参考期的长期平均值。变量包括气温（最高、最低和平均值）、降水量、日照、平均海平面气压、风速、相对湿度、蒸汽压、积雪天数和地面霜冻天数。

本数据集取代了之前版本的该数据集，后者也取代了UKCP09格网观测数据。后续版本将适时发布，并遵循Hollis等人（2018年）概述的版本编号规则。

值得关注的是，历史数据的恢复改善了1862-1910年的月降水量、1883-1910年的日降水量、1900-1909年的月温度，并增加了1919-1928年的额外日照网格。

这些数据的主要目的是促进英国气候的监测以及气候变化、影响和适应的研究。数据集由气象局创建，并由商业、能源与工业战略部（BEIS）和环境保护、食品与农村事务部（DEFRA）提供资金支持，以支持公共气象服务客户组（PWSCG）、哈德莱气候中心气候项目以及英国气候预测（UKCP18）项目。补充19世纪和20世纪初数据可用性的数据恢复活动也获得了自然环境研究委员会（NERC资助编号：NE/L01016X/1）项目“分析英国历史干旱和水短缺”的资金。该数据集在开放政府许可下提供。
