Cover Story: Tropical forests store globally significant amounts of carbon as aboveground biomass (AGB). Light detection and ranging (LiDAR) and optical wavelength data are increasingly being used to map tree height and to estimate AGB. In the tropics, cloud cover is prevalent, and so several years of satellite data may need to be considered. This may reduce mapping accuracy because of seasonal and interannual changes in forest reflectance. The sensitivity of tree height and AGB estimation derived using airborne LiDAR data with respect to the season of Landsat acquisition was examined. The quantitative results suggest that using a single cloud-free Landsat-8 image may be sufficient for dominant canopy height and AGB mapping, but that use of Landsat imagery from different seasons is preferred for improving Congo Basin forest inventories.View this paper.
