Recent demonstrations of the retrieval of vegetation solar-induced fluorescence (SIF) emission from satellite platforms have opened up the possibility of remotely monitoring photosynthetic function, in addition to the structural and biochemical parameters that characterize the current capabilities of vegetation observing systems. The Chlorophyll Fluorescence Imaging Spectrometer (CFIS) was recently developed for OCO-2 validation purposes and provides an airborne capability to help fill the spatial gap between leaf- or canopy-level observations of SIF flux and extensive satellite footprints. CFIS is a high-resolution (<0.1nm) spectrometer covering the 740-770 nm wavelength range, optimized for SIF quantification. The flexibility of an airborne instrument allows for studies of the temporal variability of SIF emission over consecutive days, or with meteorological variability throughout a day. Here we present an overview of the instrument design and capabilities, along with the retrieval methodology. We discuss the CFIS airborne campaign conducted across Northwestern Canada and Alaska as part of the 2017 Arctic-Boreal Vulnerability Experiment (ABoVE). This campaign provided an opportunity to acquire data over a variety of northern latitude ecosystems. We provide an overview of near- and long-term plans for analysis in the context of field data and multi-sensor synthesis.
