QeRSIF: A quality-enhanced red solar-induced chlorophyll fluorescence dataset for TROPOMI satellite

The QeRSIF dataset spans June 2018 to March 2025, with a spatial resolution of 0.05° and a temporal resolution of 8 days. As a novel global terrestrial satellite-based quality-enhanced RSIF product, QeRSIF provides critical data support for advancing studies of vegetation photosynthesis, global carbon cycling, climate change responses, and agricultural monitoring. The dataset will be continuously updated at https://data.casearth.cn/thematic/Liulab. For detailed information, please visit https://www.tandfonline.com/doi/full/10.1080/15481603.2026.2632999. QeRSIF data are stored in NetCDF4 files in the form of 2D arrays, including the following components: 1. SIF products: QeRSIF, data-driven retrieved RSIF, and retrieval error estimate (RSIF_err). Caltech FRSIF is included in selected time series. 2. Auxiliary data: Data used for QeRSIF production, including NDVI and NIRv derived from MODIS albedo data, and PAR calculated from ERA5 reanalysis data. 3. Other data: Including DRSIF (denoise RSIF), SRSIF (spatiotemporally filtered RSIF), and grid_count (number of observations within each grid cell). Additionally, the QeRSIFCaltech (generated by RSIFCaltech) product is provided, with the same structure as described above.
