No noise (smoothed) Normalized Difference Vegetation Index (SMN)

Global, 4 km, 7-day composite, validated. The SMN is derived from no noise NDVI, which components were pre- and post-launch calibrated. SMN can be used to estimate the start and senescence of vegetation, start of the growing season, phenological phases.

Note: For the area without vegetation (desert, high mountains, etc.), the displayed indices characterize surface conditions.

*** Data source: GVH derived vegetation indices; 'week' defined here is based on 'day of the year', i.e. week 1 covers day-of-the-year 1 to 7.
