Gridded estimates of daily and monthly areal rainfall for the United Kingdom (1890-2017) [CEH-GEAR]

1 km gridded estimates of daily and monthly rainfall for Great-Britain and Northern Ireland (together with approximately 3000 km2 of catchment in the Republic of Ireland) from 1890 to 2017. The rainfall estimates are derived from the Met Office national database of observed precipitation. To derive the estimates, monthly and daily (when complete month available) precipitation totals from the UK rain gauge network are used. The natural neighbour interpolation methodology, including a normalisation step based on average annual rainfall, was used to generate the daily and monthly estimates. The estimated rainfall on a given day refers to the rainfall amount precipitated in 24 hours between 9am on that day until 9am on the following day. The CEH-GEAR dataset has been developed according to the guidance provided in BS 7843-4:2012.

本数据集提供了1890年至2017年期间，大不列颠及北爱尔兰地区（包含爱尔兰共和国境内约3000平方千米的汇水流域）的1千米分辨率网格日降水量与月降水量估算数据。该降水估算结果源自英国气象局（Met Office）全国实测降水数据库。为生成此类估算数据，研究团队采用了英国雨量站网的月降水总量与完整月份的日降水总量数据。本次估算采用自然邻域插值法（natural neighbour interpolation），其中包含基于年平均降水量的归一化处理步骤，以生成日、月降水估算结果。单日估算降水量指当日上午9时至次日上午9时的24小时累计降水量。CEH-GEAR数据集是依据BS 7843-4:2012标准中的规范开发完成的。

背景概述

该数据集提供英国1890年至2017年的日度和月度区域降雨量格点估计，空间分辨率为1公里，基于英国雨量计网络数据采用自然邻域插值方法生成。数据格式为NetCDF，遵循英国标准BS 7843-4:2012的指导，但请注意该版本已被更新至1890-2019年的版本所取代。
