SIF

Historical Solar-Induced Fluorescence of Chlorophyll

Global map of solar-induced fluorescence.

Solar-Induced Fluorescence derived along ERS-2 GOME orbital tracks on 1 July 1995.

Global estimates of solar-induced fluorescence (SIF) of chlorophyll from 1995 to 2003 are now available.

Global Solar-Induced Chlorophyll Fluorescence (SIF)

Solar-induced chlorophyll fluorescence.

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.

High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.
