repository corresponding to 'Sustained Non-Photochemical Quenching Shapes the Seasonal Pattern of Solar-Induced Fluorescence' within JGR-Biogeosciences
This source code was used to perform the SIF simulations described in Raczka et al., (2019) JGR-Biogeosciences. The three formulation are CLM-SIF, CLM-SIF-NPQ and CLM-SIF-NPQ-Kr.
**IMPORTANT: CLM-SIF was designed for general use (multi-site/regional/global simulations) -no calibration specific to Niwot Ridge. CLM-SIF-NPQ and CLM-SIF-NPQ-Kr include parameterizations specific to Niwot Ridge site simulations, not designed for general use.
Solar induced fluorescence description for each model formulation:
CLM-SIF: Adopted from Lee et al., (2015), adds the impact of nitrogen limitation on Ja. Uses Flexas et al., (2002) data to parameterize reversible NPQ.
CLM-SIF-NPQ: Includes representation of both sustained and reversible NPQ. Sustained NPQ based upon acclimation model of temperature. Both sustained and reversible NPQ uses PAM fluorometry observations taken at Hyytiala, Finland, and adopted to Niwot Ridge Colorado.
CLM-SIF-NPQ-Kr: Similar to above but uses seasonal varying representation of reversible NPQ.
