Yearly cycle of plant greenness, haze-resistant (Terra, 500 m)

MODIS/Terra EVI Phenology annual L4 500m SIN Grid
land NASA LAADS Level 4 active HDF-EOS
In plain English

What it measures. The year-long cycle of how green and leafy the land is, using a vegetation index designed to see through haze better than older measures. The data are smoothed and gap-filled across the year.

How it's made. Derived from the MODIS instrument on the Terra satellite, built up from its 8-day surface-reflectance product into a yearly, gap-filled, smoothed map at 500-meter resolution.

How & where you'd use it. Useful for tracking growing seasons, crop cycles, and how vegetation responds to climate from one year to the next.

Official description

The MODIS/Terra EVI Phenology annual L4 500m SIN Grid product, with short-name MOD09A1P_EVI is a Gap-filled Smoothed EVI created from the MOD09A1 8-day Surface Reflectance product. The spatial resolution is 500 m. MOD09A1P_NDVI is stored in Hierarchical Data Format (HDF) with sinusodial projection, same as other standard MODIS land products.
