Gridded estimates of hourly areal rainfall for Great Britain 1990-2016 [CEH-GEAR1hr] v2

The dataset contains 1km gridded estimates of hourly rainfall for Great Britain for the period 1990-2016. The estimates are derived by applying the nearest neighbour interpolation method to a national database of hourly raingauge observations collated by Newcastle University and the UK Centre for Ecology & Hydrology (UKCEH). These interpolated hourly estimates were then used to temporally disaggregate the CEH-GEAR daily rainfall dataset. The estimated rainfall on a given hour refers to the rainfall amount accumulated in the previous hour. The dataset also contains data indicating the distance between the grid point and the closest recording raingauge used in its interpolation. When this distance is greater than 50km, or there is zero rainfall recorded in the closest gauge, the daily value is disaggregated using a design storm. The dataset therefore also contains a flag indicating if the design storm was used. These data are provided as an indicator of the quality of the estimates.

本数据集收录了1990年至2016年间，针对大不列颠地区1公里网格分辨率的小时降雨量估算数据。该估算数据通过应用最邻近插值方法，对纽卡斯尔大学及英国生态与水文中心（UKCEH）所编纂的全国性小时降雨观测数据库进行处理而得。经插值得到的小时降雨估算值，随后被用于对CEH-GEAR每日降雨数据集进行时间分辨率降低。特定小时的降雨估算值，指的是上一小时内累积的降雨量。此外，数据集还包含了指示网格点与用于其插值的最邻近降雨观测站之间的距离的数据。当此距离超过50公里，或最邻近的观测站记录的降雨量为零时，每日值将利用设计暴雨进行分解。因此，数据集中还包含了一个标志，用以指示是否使用了设计暴雨。这些数据作为估算质量指标提供。关于本数据集的详细信息，可通过以下链接获取：https://doi.org/10.5285/fc9423d6-3d54-467f-bb2b-fc7357a3941f
