Clumping index (CI) describes the spatial distribution pattern of foliage, and is a critical parameter to characterize the terrestrial ecosystem and model land-surface processes. Global and regional scale CI maps have been generated from POLDER, MODIS, and MISR sensors based on an empirical relationship with the normalized difference between hotspot and darkspot (NDHD) index by previous studies. However,...
Clumping index (CI) indicates the spatial distribution pattern of foliage. It is important for evapotranspiration (ET) and net primary productivity (NPP) estimation. Remote sensing methods offer an opportunity for CI estimation at the global scale. However, higher resolution and more stable temporal CI are critical for spatial and seasonal characteristic understanding of CI. In this study both 275...
