The MODIS Terra MOD16A2GF Version 6.1 product provides a gap-filled 8-day composite of Evapotranspiration (ET) and Latent Heat Flux (LE) at 500 m spatial resolution. The dataset is based on an algorithm derived from the Penman-Monteith equation, which integrates daily meteorological reanalysis data with MODIS-derived variables such as vegetation dynamics, albedo, and land cover. The gap-filled product is generated at the end of each year once the complete annual MOD15A2H LAI/FPAR dataset becomes available. Poor-quality LAI/FPAR inputs are identified using quality control flags and replaced through linear interpolation to improve data consistency. The dataset includes layers for ET, LE, Potential Evapotranspiration (PET), and Potential Latent Heat Flux (PLE), along with a quality control layer. ET and PET values represent the sum of daily values within each 8-day compositing period, while LE and PLE represent the average of the same period.
