Description

The downscaled solar-induced chlorophyll fluorescence (DSIF)  product (wavelength at 740 nm) had a spatial resolution of 0.05° and a temporal resolution of 8 days.

The difference between version 1:

(1) Before spatial downscaling, we upscaled SIF from instantaneous clear-sky observations to all-sky sums  (according to https://doi.org/10.1016/j.agrformet.2021.108439), while use cos (SZA) instead of PAR.

(2) After spatial downscaling, we used the ratio of ERA5 PAR to PAR under clear-sky to convert clear-sky SIF to all-sky SIF.
