Abstract

Although long-term consistent observations of LAI play a significant role in understanding the Earth system and its change, there is no reliable, consistent and accurate LAI product available due to estimation errors, data gaps and inconsistency among data. This paper presents a method, based on the multiresolution tree (MRT), to integrate satellite LAI data with different resolutions. The results of integrating MODIS and MISR LAI show MRT has the capability of filling data gaps, reducing measurement errors and can also generate consistent results across scales. When compared with optimal interpolation (OI), MRT produces similar results but with significantly improved efficiency.
