Global leaf cover and light absorption, 8-day 500m (Copernicus)
What it measures. Estimates how much leaf area canopies hold and what fraction of useful sunlight plants absorb for growth, summarised every eight days at 500-metre detail.
How it's made. Calculated from MODIS observations on NASA's Aqua satellite by selecting the best pixel in each 8-day window, a modelled (Level 4) product.
How & where you'd use it. Feeds crop, forest, and ecosystem models and helps study plant productivity, carbon uptake, and how vegetation responds to weather and climate.

Official description
The MODIS Aqua MYD15A2H Version 6.1 product provides an 8-day composite of Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) at 500 m spatial resolution. The dataset is generated by selecting the best available pixel from all Aqua MODIS acquisitions within the 8-day compositing period. LAI represents the one-sided green leaf area per unit ground area in broadleaf canopies and half the total needle surface area per unit ground area in coniferous canopies. FPAR describes the fraction of incoming photosynthetically active radiation (400-700 nm) absorbed by the green vegetation canopy. The Level-4 product includes science datasets for LAI and FPAR, two quality control layers, and standard deviation layers for both variables. Additionally, low-resolution browse images for LAI and FPAR are provided for each granule.
