Changes to this version primarily involve replacing MODIS fPAR with VIIRS fPAR as the new baseline fPAR input for the carbon model processing; and BPLUT recalibration and SOC re-initialization in response to updates to the upstream SPL4SMGP input datasets. Specifically: - Replaced NASA EOS MODIS (MOD15A2H) fPAR with NOAA/NASA Suomi NPP VIIRS (VNP15A2H) fPAR as the new baseline 8-day fPAR inputs to the L4C model; generated a new ancillary global clear-sky fPAR climatology from the long-term (2012-2021) VIIRS record. This update enables extended L4C operations beyond the EOS MODIS era through ongoing VIIRS operations. - Revised SPL4CMDL global BPLUT calibration and SOC initialization using soil moisture and soil temperature data from the latest SMAP L4SM Open Loop (OL7000) ensemble Catchment land model simulation. The revision results in a calibration that is more consistent with the ensemble SPL4SMGP inputs used in SPL4C production than the calibration with the single-member, unperturbed L4SM Nature Run (NR) data used in prior L4C product releases. - The carbon model BPLUT, Vv7040, was recalibrated using the FLUXNET2015 global tower site record, which includes 356 sites representing all major global PFT classes.
