Table 4 Overview of key variables in NetCDF files of gridded indices (in addition to standard variables of time, latitude and longitude).
From: An Observation-Based Dataset of Global Sub-Daily Precipitation Indices (GSDR-I)
Variable | Description |
|---|---|
index (e.g. Rx1hr) | Index (e.g. Rx1hr) or statistic (e.g. percentile) value obtained via angular distance weighting gridding |
n_cell | Number of gauges available within grid cell for calculation |
n_radius | Number of gauges within search radius of grid cell centre (i.e. total number of gauges used in calculation) |
cell_statistics | Index value for grid cell obtained by summarising gauges within grid cell (i.e. providing minimum, median, mean and maximum of index/statistic values for those gauges within the grid cell) |
n_years | For supplementary statistics (percentile, diurnal profile) only, mean number of years of record available from gauges contributing to the gridded values |
