ERA5-Land selected indicators daily aggregates for Africa, 2019

This deposit contains NetCDF files with daily aggregates from Copernicus Era5-Land for eight selected indicators, covering Africa for 2019. 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.本数据集包含8个选定指标的日聚合数据文件，数据格式为NetCDF（网络公共数据格式），源自哥白尼Era5-Land（Copernicus Era5-Land）陆地再分析数据集，覆盖2019年的非洲区域。每个文件对应单一年份中单个月份的某一指标的聚合结果。每个NetCDF文件内的图层均存储有对应的日聚合数据。针对2米露点气压、10米风u分量、10米风v分量以及地表气压四类指标，采用均值函数进行聚合计算；针对总降水量指标，采用求和函数进行聚合计算；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计算。本数据集的所有NetCDF文件均通过KrigR包生成。
