Abstract

Measurement capabilities of a new optical disdrometer called High-speed Optical Disdrometer (HOD) were evaluated through a comparative study with the 2- Dimensional Video Disdrometer (2DVD), and the Pluvio200 weighing bucket rain gauge. All instruments were collocated at the Maggie Valley site of the Integrated Precipitation Hydrology Experiment (IPHEx) field campaign. This field campaign was a joint effort between NASA’s Global Precipitation Measurement (GPM) ground validation program, Duke University, and NOAA’s Hydrometeorology Test bed- South East. Collocated measurements were conducted for a heavy rain event (conditional mean rain rate of 18.7 mm h-1 based upon 2DVD) on May 13, 2014. This comparative study seeks the degree of agreement among precipitation measuring instruments for the rain total, raindrop size distribution, and fall velocity.
