This research opportunity seeks innovative work to identify biochemical and environmental controls on ecosystem productivity. The approach is to combine observations of solar induced chlorophyll fluorescence (SIF) from a growing network of tower, airborne, and spaceborne sensors, with ancillary biometeorological data, to explore the functioning of photosynthesis under different light, temperature, and moisture conditions and canopy structures. Analysis of ecosystem productivity in the context of a carbon cycle data assimilation system, in which model equations are confronted with a suite of vegetation, carbon, and water cycle observations and weighted by their respective uncertainties, is highly desired. Incorporation of observations from OCO-2, TROPOMI, and ground sensors (e.g., Grossman et al., 2018) are likely to provide significant advances.
