Sun induced-chlorophyll fluorescence at 760nm (SIF760) and the apparent fluorescence yield (SIF760/a, with a=irradiance at time of measurement) were extracted from the radiance spectra of canopies using the Fraunhofer Line Discrimination-method. The photosynthetic parameters derived from Kautsky ...
where ρλ represents the TOA reflectance on the satellite image band wavelength, d is the Earth–sun distance, ESUNλ is the solar exoatmospheric irradiance, and θs is the solar zenith angle [38]. 𝜌𝑇𝑂𝐶=𝜌𝑇𝑂𝐴−𝜌𝑎𝑡𝑚𝑇(𝜇𝑠)𝑇(𝜇𝛾)𝑡𝑔1+...
It is equipped with a bare fiber-optic sensor (25° FOV) for downward radiance observations (μW/cm2·nm·sr) and a cosine corrector sensor (180° FOV) for upward irradiance observations (μW/cm2·nm). 4. To ensure accuracy and prevent potential FOV matching issues, this spectrometer ...
LO and LT are the radiance from an inclined surface and normalized radiance, respectively; and k is the Minnaert constant, which gives a measure of the deviation from a Lambertian surface, k equal to 1 indicating a Lambertian surface with most natural surfaces having values between 0 and 1. ...
