Description

In this study, we present the first evaluation study of rainfall retrieval using commercial microwave link data for the oceanic temperate climate using one year of received signal level data collected from 115 microwave links (recorded at 15-minutes interval with minimum, maximum and average sampling strategy). The open-source package RAINLINK was applied to retrieve the rainfall intensities confirming that the package can be applied for the average logged data as well. Rainfall intensities for all links are validated with the path-average rainfall intensities obtained from the gauge-adjusted radar product and automatic rain gauges. Comparison of our results showed that average sampling outperforms Min/Max sampling regarding both the occurrences and quantity at a 15-minutes sampling rate for the Melbourne climate.
