HadUK-Grid Climate Observations by UK river basins, v1.0.0.0 (1862-2017)

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 1km 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 2017, but the start time is dependent on climate variable and temporal resolution. The grids 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 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).

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 是一套从英国陆地观测网络中派生出的栅格气候变量集。这些数据通过对气象站数据的插值，被投射到统一的网格上，以实现对英国全境的完整且一致覆盖。该数据集以 1 公里分辨率为标准，对一系列离散的地理区域（与 UKCP18 气候预测数据相一致）进行了平均处理，从而定义了英国河流流域。数据集覆盖了 1862 年至 2017 年的时期，但起始时间依赖于气候变量和时间分辨率。网格数据覆盖了每日、每月、每季、每年以及一系列气候参考时期的长期平均值。变量包括空气温度（最高值、最低值和平均值）、降水量、日照时间、平均海平面气压、风速、相对湿度、水汽压、积雪天数以及地面霜冻天数。

此数据集取代了 UKCP09 栅格观测数据。后续版本将按 Hollis 等人（2018 年，参见相关文档）概述的版本编号规则陆续发布。

这些数据的主要目的是为了便于监测英国气候和气候变化、影响及适应性的研究。数据集由气象局创建，并获得商务、能源与工业战略部（BEIS）和环境保护、食品与农村事务部（DEFRA）的财政支持，以支持公共气象服务客户组（PWSCG）、Hadley 中心气候项目以及英国气候预测（UKCP18）项目。补充 19 世纪和 20 世纪初数据的恢复活动也得到了自然环境和研究委员会（NERC，资助编号：NE/L01016X/1）项目“英国历史干旱和水匮乏分析”的资助。该数据集在开放政府许可下提供。
