Characterization and intercomparison of global moderate resolution leaf area index (LAI) products: Analysis of climatologies and theoretical uncertainties

Abstract Leaf area index (LAI) is a critical variable for land surface and climate modeling studies. Several global LAI products exist, and it is important to know how these products perform and what their uncertainties are. Five major global LAI products—MODIS, GEOV1, GLASS, GLOBMAP, and JRC‐TIP—were compared between 2003 and 2010 at a 0.01° spatial resolution and with a monthly time step. The daily Land‐SAF product was used as a regional …
