A revised set of phenology metrics have been released for 2003 – 2017. This suite of phenology metrics was
derived from time-series Collection 6 Aqua eMODIS Normalized Difference Vegetation Index (NDVI) data.

Historical remote sensing phenology (RSP) image data and graphics for the conterminous U.S. are made freely available from the USGS/EROS Center through this website.
Five data sets are distributed: CONUS 1 km AVHRR RSP data, C5 Eastern CONUS 250 m eMODIS RSP data, C6 Eastern CONUS 250 m eMODIS RSP data, C5 Western CONUS 250 m eMODIS RSP data, and C6 Western CONUS 250 m eMODIS RSP data.
Due to sensor degradation of the MODIS Terra sensor, particularly for the period after 2007, we recommend that users work with the C6 eMODIS RSP datasets which are derived from AQUA MODIS C6 NDVI data.
Users of these phenology data sets should cite this DOI: https://doi.org//10.5066/F7PC30G1
