Data release associated with the journal article "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States" 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 data and code provided allow users to replicate, test, or further explore results. The dataset includes 2 raster datasets (folder:Rasters): 1) 'cntWinterPks2003_2018DR' provides a count of years with winter peaks from 2003-2018 in an 11-state area in the western United States. 2) 'VegClassGte5_2003_2018' raster, within the zip file 'WinterPeaksVegTypes.zip' identifies the broad vegetation types for locations with common winter peaks (5 or more years out of 16). The dataset also includes Google Earth Engine... Tags: Arizona, California, Colorado, Idaho, Montana, All tags...

The data are provided in support of the following publication: "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States". The data and scripts allow users to replicate, test, or further explore results. The file GrcaScpnModisCellCenters.csv contains locations (latitude-longitude) of all the 250-m MODIS (MOD09GQ) cell centers associated with the Grand Canyon pinyon-juniper ecosystem that the Southern Colorado Plateau Network (SCPN)...
