Identifying Individual Rain Events with a Dense Disdrometer Network

الملخص EN

The use of point detectors to measure properties of rainfall is ubiquitous in the hydrological sciences.

An early step in most rainfall analysis includes the partitioning of the data record into “rain events.” This work utilizes data from a dense network of optical disdrometers to explore the effects of instrument sampling on this partitioning.

It is shown that sampling variability may result in event identifications that can statistically magnify the differences between two similar data records.

The data presented here suggest that these magnification effects are not equally impactful for all common definitions of a rain event.
