SIF Products: What They Are and How They're Used

SIF products are derived from satellite data and represent the vegetation's nighttime photosynthetic fluorescence (Solar-Induced Fluorescence or SIF). SIF is the energy released by plants through fluorescence when exposed to sunlight, providing insights into the intensity and health of their photosynthetic processes. Different satellites employ distinct sensors and observation methods, resulting in variations in the SIF data obtained through different algorithms. Therefore, SIF products can be named according to the satellite data used in their derivation, such as 'OCO-2 SIF products' which are derived from OCO-2 satellite data. These SIF products are valuable tools for scientific research on topics including vegetation growth, photosynthetic rates, and carbon cycling.
