Abstract

The foliage Clumping Index (CI) is a key vegetation structure parameter for leaf area index (LAI) estimating and ecological modelling. Previously, several global CI products have been retrieved from the Collection V005 Moderate Resolution Imaging Spectroradiometer (MODIS) Bidirectional Reflectance Distribution Function (BRDF) products with a temporal resolution of one year, one month or 8 day. The Collection V006 MODIS BRDF products provide a chance to retrieve a global CI product with higher temporal resolution and data accuracy. However, the large size of the Collection V006 MODIS BRDF products (~150 terabyte from January 2001 to December 2017) and the retrieved CI products (~9 terabyte) increases the difficulty in retrieving and publishing the global CI product. In this study, we develop a software tool that enable users to produce CI product of their desired date, region and temporal resolution based on the Collection V006 MODIS land cover type and BRDF products. The software tool reduces the requirements of the processing and storage capacity for researchers and thus facilitate the publication and widespread application of the CI product.
