Solar Induced Chlorophyll Fluorescence from the leaf through the global scale
Abstract
New satellite measurements from space as well as the FLEX mission have spurred research in the use of Solar Induced Chlorophyll Fluorescence (SIF) for investigations into the carbon cycle from the regional through the global scale. The Orbiting Carbon Observatory, launched in July 2014, now provides SIF data at unprecedented spatial resolution of less than 3km2. In addition, JPL built the airborne Chlorophyll Fluorescence Imaging Spectrometer (CFIS) for OCO-2 validation and local studies. For the local scale, the PhotoSpec project, funded by the Keck Institute for Space Studies and JPL now enables the acquisition of high resolution spectra on the ground at flux-tower sites. For the leaf level scale, we developed a system to combine Pulse Amplitude Modulated fluorescence measurements with spectrally resolved measurements of SIF and saturation pulse induced maximum fluorescence. This talk will summarize recent measurement advances for SIF, with a particular focus on the CFIS instrument and campaigns in 2015/2016 in the continental US.
