When plants green up and brown down at tower sites (North America)

Land Surface Phenology, Eddy Covariance Tower Sites, North America, 2017-2021
biosphere NASA ORNL_CLOUD Level 3 multiple
In plain English

What it measures. Tracks the seasonal rhythm of plant life around 104 monitoring towers in North America: when vegetation greens up in spring, hits its peak, and browns down in fall, plus greenness scores and quality flags.

How it's made. Built from very high-resolution (3-meter) PlanetScope satellite images covering 10-by-10 km areas around each tower, processed into seasonal-timing measures for the 2017-2021 growing seasons.

How & where you'd use it. Researchers use it to check other satellite greening products, test land-surface model predictions, and study what drives the seasonal flow of carbon, water, and energy between ecosystems and the air.

Official description

This land surface phenology (LSP) dataset provides spatially explicit data related to the timing of phenological changes such as the start, peak, and end of vegetation activity, vegetation index metrics and associated quality assurance flags. The data are for the growing seasons of 2017-2021 for 10-km x 10-km windows centered over 104 eddy covariance towers at AmeriFlux and National Ecological Observatory Network (NEON) sites. The dataset is derived at 3-m spatial resolution from PlanetScope imagery across a range of plant functional types and climates in North America. These LSP data can be used to assess satellite-based LSP products, to evaluate predictions from land surface models, and to analyze processes controlling the seasonality of ecosystem-scale carbon, water, and energy fluxes. The data are provided in NetCDF format along with geospatial area-of-interest information and visualizations of the analysis window for each site in GeoJSON and HTML formats.
