How green the land gets through the year (Terra, 250 m)

MODIS/Terra EVI Phenology annual L4 250m SIN Grid
land NASA LAADS Level 4 active HDF-EOS
In plain English

What it measures. A yearly, gap-filled and smoothed record of how green the land becomes through the seasons, at 250-meter resolution. It uses a vegetation 'greenness' index (EVI) to track the plant growing cycle.

How it's made. Built from the Terra satellite's MODIS 8-day surface reflectance data, then gap-filled and smoothed into a clean annual series.

How & where you'd use it. Useful for studying plant phenology - when vegetation greens up and dies back each year - and tracking growing seasons and crop or ecosystem patterns.

Official description

The MODIS/Terra EVI Phenology annual L4 250m SIN Grid product, with short-name MOD09Q1P_EVI is a Gap-filled Smoothed EVI created from the MOD09A1 8-day Surface Reflectance product. The spatial resolution is 250 m. MOD09Q1P_NDVI is stored in Hierarchical Data Format (HDF) with sinusodial projection, same as other standard MODIS land products.
