SIF Background and Interpretation

What is SIF?

SIF is a remote sensing index intended to monitor plant production.

More conventional indices, such as NDVI or EVI, measure greenness of vegetation-- which is less ideal for capturing changes in production that are not associated with changes in greenness, like conifers in winter, or plants with different photosynthetic types.

SIFVIZ is a map viewer displaying global seasonal shift in SIF.

Greater intensity of greens indicate greater seasonal change in chlorophyll fluorescence.

White flowing shapes demonstrate direction of increased chlorophyll concentration across seasons.
