  • Abstract:

    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.

  • Methods:

    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.

Detailed Metadata

hf165-01: 15-minute

  1. datetime: date and time at end of sampling period
  2. jd: Julian day (unit: nominalDay )
  3. wspd: horizontal scalar wind speed. Average of 1-second measurements. (unit: metersPerSecond / missing value: NA)
  4. wres: horizontal resultant vector wind speed. Vector average of 1-second measurements. (unit: metersPerSecond / missing value: NA)
  5. wdir: horizontal vector wind direction. Vector average of 1-second measurements. Measured in degrees clockwise from true north. (unit: degree / missing value: NA)
  6. wdev: standard deviation of wind direction. Calculated from 1-second measurements using Campbell Scientific equation. (unit: degree / missing value: NA)
  7. gspd: gust speed. Maximum of 1-second measurements. (unit: metersPerSecond / missing value: NA)
