Rain Gauge Inter-Comparison Quantifies Deficiencies in Precipitation Monitoring

Efforts to correct precipitation measurements have been ongoing for decades, but are scarce for tropical highlands. Four tipping-bucket (TB) rain gauges with different resolution that are commonly used in the Andean mountain region were compared—one DAVIS-RC-II, one HOBO-RG3-M, and two TE525MM TB gauges (with and without an Alter-type wind screen). The relative performance of these rain gauges, installed side-by-side in the Zhurucay...
