Evaluation of the escape probability method that we have incorporated in the Community Land Model version 5 with the Soil Canopy‐Observation of Photosynthesis and Energy fluxes model for (a) hemispherically integrated solar‐induced chlorophyll fluorescence (SIF) at top‐of‐canopy (TOC) (SIF_hem) and (b) TOC SIF at the nadir direction (SIF_nadir). Large SIF values not expected to be found in observations are simulated with combinations of extreme input parameter values. Evaluation with a more realistic SIF_nadir range of 0–10 W⋅m⁻²⋅sr⁻¹⋅μm⁻¹ is provided as Figure S3 in Supporting Information S1.
