Global Retrieval of 24-hourly Solar-Induced Chlorophyll Fluorescence and Evapotranspiration from OCO-2, OCO-3 and ECOSTRESS over 1982–2022

We developed an efficient modeling algorithm and produced a long-term global SIF and ET dataset (0.1°, hourly, from 1982 to 2022), which has been validated using global EC flux towers and popular satellite products. Our dataset will provide new insights for monitoring the diurnal variations of carbon and water cycles and deepen our understanding of their changes over the past 41 years.All products are provided in NetCDF4 format. Our dataset contains four main fields: SIFOCO, which represents continuous SIF data obtained by extending canopy-level SIF from OCO-2 and OCO-3 observations; SIFtotal-D, which represents photosystem-level SIF directly calculated based on a radiative transfer model; SIFtotal-S, which represents photosystem-level SIF obtained from the SCOPE model; and ETECO, which represents continuous ET data obtained by scaling ECOSTRESS observations. Detailed descriptions of these four main fields, including units, coverage, and other relevant information, are included in the NetCDF4 files.
