The Barn Tower (40 m) was installed in 2009 to support meteorological and phenological measurements and to provide a relay point for the Harvard Forest field wireless network. A wind instrument was later installed at the top of the tower to provide continuous measurements of wind speed and direction.

The wind instrument is an R.M. Young 05103 wind monitor. The instrument is scanned once per second and 15-minute values are calculated and stored by a datalogger. Date-time values indicate the end of each measurement period. All times are Eastern Standard Time. Missing values are indicated by NA. The original instrument was replaced on 6 May 2021.
