A disdrometer is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. Some disdrometers can distinguish between rain, graupel, and hail.{{Cite web|url=https://www.arm.gov/capabilities/instruments/disdrometer|title = ARM Research Facility}}

The uses for disdrometers are numerous. They can be used for traffic control, scientific examination, airport observation systems, and hydrology. The latest disdrometers employ microwave or laser technologies. 2D video disdrometers can be used to analyze individual raindrops and snowflakes.{{Cite journal |doi = 10.1002/asl.376|title = A Joss-Waldvogel disdrometer derived rainfall estimation study by collocated tipping bucket and rapid response rain gauges|journal = Atmospheric Science Letters|volume = 13|issue = 2|pages = 139–150|year = 2012|last1 = Islam|first1 = Tanvir|last2 = Rico-Ramirez|first2 = Miguel A.|last3 = Han|first3 = Dawei|last4 = Srivastava|first4 = Prashant K.|bibcode = 2012AtScL..13..139I| s2cid=123002855 }}
