Data Table

  • Title: Raw Forest Canopy Meteorological Tower Data
  • Start Date: 1992-08-13
  • Description: Meteorological data, including wind speed and direction, leaf wetness, temperature and humidity, collected at each of four heights from the forest floor to above the canopy at Proctor Maple Research Center. The canopy tower also captures measurements of solar radiation.

  • Purpose: Long-term continuous measurements of meteorological variables in and above a hardwood forest canopy to use in relation with other biological or physical variables within the forest.
