The PhenoCam Network uses imagery from digital cameras to track vegetation phenology and seasonal changes in vegetation activity in diverse ecosystems across North America and around the world. Imagery is uploaded to the PhenoCam server at the University of New Hampshire, where it is made publicly available in near-real time, every 30 minutes from sunrise to sunset, 365 days a year. The data are processed using simple image analysis tools to yield a measure of canopy greenness, from which phenological metrics are extracted, characterizing the start and end of the growing season. These transition dates have been shown to align well with on-the-ground observations of tree phenology at Harvard Forest (HF003). Long-term PhenoCam data can be used to track the impact of climate variability and change on the rhythm of the seasons. This dataset contains one mid-day image for each camera. Please see the PhenoCam Network website (https://phenocam.nau.edu/webcam/) for more information and additional images.

Webcams at this location record images at 30-minute intervals during daylight hours. These images are then uploaded to the project archive at the University of New Hampshire. The Hemlock Tower NE camera (since 2010) is mounted on the Hemlock Tower at a height of 25 meters with a view toward the northeast. The Hemlock Tower SW camera (since 2015) is mounted on the Hemlock Tower at a height of 25 meters with a view toward the southwest.
