This dataset provides calculated camera-NDVI data for individual regions-of-interest (ROI's) for the phenocam named 'GRCA1PJ' (part of the Phenocam Network, https://phenocam.sr.unh.edu/webcam/). The GRCA1PJ phenocam is within a pinyon-juniper woodland in Grand Canyon National Park. Camera-NDVI refers to a modified version of NDVI calculated by the phenopix package (Filippa et al., 2016). The camera-calculated NDVI data are in the folder FinalOutput. File attributes within that folder are described in detail in the entity and attribute information section of this metadata. It should be possible for the user to use only the ROI definitions, image data downloaded from the phenocam network, and the phenopix R-package...

This dataset supports the following publication: "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States" (DOI:10.1016/j.rse.2020.112013). The data release allows users to replicate, test, or further explore results. The dataset consists of 4 separate items based on the analysis approach used in the original publication 1) the 'Phenocam' dataset uses images from a phenocam in a pinyon juniper ecosystem in Grand Canyon National Park to determine phenological patterns of multiple plant species. The 'Phenocam' dataset consists of scripts and tabular data developed while performing analyses and includes the final NDVI values for all areas...
The NC CSC has collaborated with the USGS AmericaView program to deploy cameras that will record phenology throughout the region. Although, not all cameras were deployed throught AmericaView, they were deployed at the following sites: Ashland Bottoms, Kansas Bangtail Study Area in Bozeman, Montana Central Plains Experimental Range, Colorado Grand River Grasslands, Iowa Grand Teton National Park National Elk Refuge, Wyoming Nine Mile Prairie, University of Nebraska, Nebraska Oakville Prairie, North Dakota Poudre Learning Center, Colorado Sagebrush Steppe, Wyoming Earth Resources Observation and Science Center, South Dakota
