Level A Pan Europe Precipitation, E-Hype 2.5

Time-series for 1961 to 2001 describing the input forcing precipitation for each E-HYPE subbasin. The data describes daily values for each subbasin (mean area 215 km2). Unit of measurement: mm. The precipitation is derived from the WFD gridded data set which consists of the ERA-40 reanalysis data set daily precipitation output (Weedon et al. 2011)corrected for wet days mean monthly precipitation and undercatch (for example to CRU and GPCC). For each subbasin, the gridpoint nearest the subbasin centroid is used. Within E-HYPE a correction is made to increase precipitation above 700 m elevation. Original data source was WFD Forcing data and HYDE was used for repurposing. The data format is a zipped text file. On the first row there is a brief description and the rest of the file contains one row per time step, with the sub basin id as each column header on the second row. The first item on each line is the time step using the format YYYY-MM-DD, so 1961-01-01 for the first of January 1961.本数据集涵盖1961年至2001年的时序数据，用于描述每个E-HYPE子流域（E-HYPE subbasin）的降水输入强迫量。数据包含各子流域的日尺度数值，子流域平均面积为215 km²，测量单位为毫米。 该降水数据源自WFD格点数据集（WFD gridded data set），其基础数据为ERA-40再分析数据集（ERA-40 reanalysis data set）的日降水输出结果（Weedon等，2011），并针对湿日平均月降水及观测漏测情况进行了校正，以匹配CRU（CRU）与GPCC（GPCC）数据集的标准。针对每个子流域，我们选取最接近其质心的格点数据。在E-HYPE模型框架内，还会针对海拔高于700米的区域的降水数据进行校正，以调高其数值。本数据集的原始数据来源为WFD强迫数据（WFD Forcing data），HYDE数据集（HYDE）被用于该数据集的重新适配与复用。 数据格式为压缩文本文件。文件首行为简要说明，第二行以各子流域ID作为列标题，剩余各行均对应一个时间步长。每行的首个字段为时间戳，格式遵循YYYY-MM-DD，例如1961-01-01代表1961年1月1日。
