ERA5-Land selected indicators daily aggregates for Africa, 1998

This deposit contains NetCDF files with daily aggregates from Copernicus Era5-Land for eight selected indicators, covering Africa for 1998. Each file represents one indicator aggregation for one month of the year. Inside each NetCDF file, the layers contain the daily aggregates. For 2m dewpoint pressure, 10m u-component of wind, 10m v-component of wind, surface pressure, the mean function was used for aggregation. For total precipitation, the sum function was used for aggregation. For 2m temperature, the functions maximum, mean, and minimum were used for aggregation. Those files were created using the KrigR package.本数据集存档包含8个选定指标的日聚合数据，数据源自哥白尼Era5-Land（Copernicus Era5-Land）数据集，存储为网络通用数据格式（NetCDF）文件，覆盖1998年的非洲区域。 每个文件对应一年中单个月份的单个指标聚合结果。每个NetCDF文件内部的图层均存储了日聚合数据。 针对2米露点气压、10米风速u分量、10米风速v分量以及地面气压这四项指标，采用均值函数进行聚合运算；针对总降水量指标，采用求和函数进行聚合运算；针对2米气温指标，则分别采用最大值、均值以及最小值函数进行聚合运算。 本数据集的所有文件均通过KrigR软件包生成。
