The data spans from April 7, 2013, to April 7, 2017, and is composed of 32-day periods. The EVI, with values from -1.0 to 1.0, is derived from Near-IR, Red, and Blue bands, with a pixel size of 30 meters. The USGS discontinued producing this pre-collection data as of May 1, 2017, recommending a shift to Collection 1-based datasets. The data is public domain.\n"]]
