Data Quality: Reading Beam Velocities

Check Your Gear Before You Collect Data

Duration: 2:57

When looking at 2-dimensional Doppler velocity data, do you know how to use "Beam" velocities as a diagnostic tool? Because the water "coming in" through the upstream beam should be equal to the water "going out" through the downstream beam, this means you should look for beam velocities that are roughly equal in magnitude, one a positive number and one a negative number.
