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.   The available phenological metrics are Start of Season Time (SOST), Start of Season NDVI (SOSN), End of Season Time (EOST), End of Season NDVI (EOSN), Maximum Time (MAXT), Maximum NDVI (MAXN), Duration (DUR), Amplitude (AMP), and Time Integrated NDVI (TIN).

Seven 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, C6 Western CONUS 250 m eMODIS RSP data, Eastern CONUS 375 m eVIIRS RSP data, and Western CONUS 375 m eVIIRS RSP data. (Note: 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.) 

Starting with 2021 CONUS RSP products, eVIIRS-based RSP will be developed and will replace eMODIS 250 m RSP data.
