Table 5 Correlation coefficient flag codes and their definitions.

From: Hourly rainfall data from rain gauge networks and weather radar up to 2020 across the Hawaiian Islands

Correlation Coefficient flag code (CORR_FLAG)

Definition

Not applicable

The flag is not applicable on the gauge because there is not enough data to compare between its data and its neighbor gauges’ data.

Warning

The gauge needs to be used with caution because it has different daily rainfall pattern with its neighbor gauges.

Pass

The gauge is reliable because its data is consistent with its neighbor gauges’ data.
