    • CLM Simulated Solar-Induced Fluorescence, Niwot Ridge, Colorado, USA, 1998-2018

    Metadata Updated: December 6, 2023

    This dataset provides results for simulations of solar-induced chlorophyll fluorescence (SIF) implemented within the terrestrial biosphere Community Land Model (CLM 4.5) for Niwot Ridge, Colorado, USA, from 1998-2018. The data include outputs from three model simulations designed to test the importance of non-photochemical quenching (NPQ), that is, the absorbed light energy dissipated as heat, in determining seasonal SIF.

    Simulated and observed seasonal patterns of canopy SIF (740 nm) for (a, c) absolute SIF and (b, d) normalized canopy SIF for CLM simulation year 2010. The CLM-SIF simulation considers reversible NPQ (kR) only, the CLM-NPQ simulation considers both reversible (kR) and sustained NPQ (kS), and CLM-NPQ-kR(t) considers kS and seasonal variation in kR. Both a satellite SIF product (GOME-2) and the PhotoSpec measurements are included for comparison. Figure from Raczka et al. (2019)
