MODIS Aqua Net Evapotranspiration Gap-Filled Yearly L4 Global 500m

The MODIS Aqua MYD16A3GF Version 6.1 product provides a yearly gap-filled composite of Evapotranspiration (ET) and Latent Heat Flux (LE) at 500 m spatial resolution. The dataset is generated at the end of each year using an algorithm based on the Penman–Monteith equation, which integrates daily meteorological reanalysis data with MODIS-derived variables such as vegetation dynamics, albedo, and land cover. The product uses quality-controlled inputs from the 8-day LAI/FPAR dataset (MYD15A2H), and pixels that do not meet quality criteria are filled through linear interpolation. The dataset includes layers for ET, LE, Potential Evapotranspiration (PET), and Potential Latent Heat Flux (PLE), along with a quality control layer. Annual ET and PET values represent the sum of daily values over the year, while LE and PLE represent the annual average. Low-resolution browse images for ET and LE are also provided for each granule.
