Size dependent particle exchange velocity (Vex) is presented in 30 minute periods, these were calculated from 10 Hz particle data and sonic data. The exchange velocities (Vex) follow the sign convention that negitive is downward and positive is upward movement. The midpoint of the size range is included in the column headers. This data was quality control filtered based on 30% stationarity bounds, friction velocity less than 0.14 m/s, and precipitation events have been removed.
