FVC, Albedo, and LAI Products for ET Downscaling in Central–Southern East Asia

This dataset provides fractional vegetation cover (FVC), broadband albedo, and leaf area index (LAI) products used to support the study “Downscaling Microwave-Based Evapotranspiration with a Fourier-Supervised Multi-Source Fusion Network in Central–Southern East Asia”. The data cover the model domain in central–southern East Asia and are prepared specifically for evapotranspiration (ET) downscaling experiments. FVC, albedo, and LAI are derived from the Global Land Surface Satellite (GLASS) products and resampled to a common spatial grid consistent with the ET datasets used in the study. The products provide 8-day composites at 0.05° spatial resolution. These vegetation and surface radiation parameters are key auxiliary inputs to the Fourier-supervised multi-source fusion network (FMED-Net), where they are used to characterize land-surface and canopy conditions and to constrain the spatial and seasonal variability of ET. The dataset is intended to facilitate reproducibility of the published work and to support further research on ET downscaling, land–atmosphere interactions, and vegetation–hydrology coupling in East Asia.
