Does Disdrometer Accuracy Apply at Every Particle Velocity?

2026-10-02English

Not necessarily. Retain velocity and other conditions stated with accuracy or resolution.

Why

Relevant 2DVD velocity accuracy and resolution statements apply below 10 m/s. Removing that condition changes their meaning.[1]

Size resolution, velocity accuracy and type-identification rate are different metrics. LPM output bins are not measurement errors.[2]

What to confirm

Compare the specific output, particle conditions and model. Without common tests, do not create a universal accuracy ranking from promotional numbers.
