             abstract = "The factors that determine the occurrence, composition and 
                         structure of tropical forests and their functional responses to 
                         climate change are still not well understood. Remote sensing 
                         provides valuable tools for investigating these factors at 
                         multiple temporal and spatial scales. This paper aims to 1) 
                         explore the influence of topography on canopy height over complex 
                         terrain coastal tropical forest sites in Australia and Brazil; and 
                         2) examine the relationship between vegetation greenness and 
                         canopy height at these forests. We used canopy height and terrain 
                         slope data derived from airborne lidar observations and Enhanced 
                         Vegetation Index (EVI) and Normalized Difference Vegetation Index 
                         (NDVI) from Landsat 8 imagery. Our results revealed different 
                         relationships between canopy heights and local topography. Over 
                         the Brazilian site, canopy height was significantly lower over 
                         flat slopes (0-10\⁰), intermediate for gentle slopes 
                         (10-30\⁰) and higher for steep slopes (>30\⁰). Such 
                         relationship, however, was not observed over the Australian 
                         tropical forest site. Meanwhile, the Brazilian site showed 
                         significant differences in canopy greenness associated to 
                         different slope ranges, while the Australian site showed 
                         significant differences only for NDVI in two slope comparisons. We 
                         found no strong correlations between vegetation greenness and 
                         canopy height. Our results indicated site-specific relationships 
                         amongst canopy height, topography and VIs values, which might be 
                         attributed to distinct disturbance regimes and local environmental 
                         conditions, as well as bidirectional reflectance distribution 
                         function (BRDF) effects. Our findings thus highlight the influence 
                         of local context on the sensitivity of vegetation greenness to 
                         canopy structural properties.",
