  • Phenology data in this dataset is collected using high frequency visible wavelength digital time-lapse imagery from a camera (referred to as a ‘PhenoCam’) mounted on the Lost Creek eddy covariance flux tower in Northern Wisconsin. The camera is part of the larger PhenoCam Network, a network of cameras installed at over 500 sites across the world to collect real-time phenology data in a diverse array of ecosystems (Richardson et al., 2018).

    This data is collected to track vegetation phenology using greenness indices, calculate growing season length, benchmark ecosystem models and remote sensing products, and study the impacts of climate change on terrestrial ecosystems. At this site specifically, phenology data is used in conjunction with eddy covariance flux estimates of surface-atmosphere exchanges of carbon and water to better understand spatial and temporal variations in the terrestrial carbon cycle.

    The camera takes images year-round, and has been in operation since 07/28/2015. Images are taken and uploaded to the PhenoCam Network server every half hour, and red, green, and blue color metrics are extracted to calculate a greenness index called the green chromatic coordinate (GCC) that corresponds to the amount of foliage present and its developmental stage.

    This dataset is part of the larger PhenoCam Network (project url: https://phenocam.sr.unh.edu/), and was processed through the PhenoCam Network data processing pipeline. The Lost Creek research site is part of the Chequamegon Ecosystem‐Atmosphere Study Ameriflux core site cluster, so this data is publicly shared with the PhenoCam Ameriflux group within the Ameriflux network.
