This document discusses water temperature and leaf area index datasets for the Zambezi River Basin and surrounding areas derived from Landsat 8 and Sentinel-2 satellite imagery. It describes the processing steps to generate water temperature and leaf area index maps at monthly intervals from 2013 to 2016. Additional datasets provided for analysis include Landsat imagery, land use classifications, waterbody maps, and demographic data for the Zambezi and Omo River basins.
