The atmospheric boundary layer height (zi) is a key parameter in the vertical transport of mass, energy, moisture, and chemical species between surface free atmosphere. There lack long-term continuous observations zi, however, particularly for remote regions, such as Amazon forest. Reanalysis products, ERA5, can fill this gap by providing temporally spatially resolved information on zi. In work, we evaluate ERA5 estimates zi (zi-ERA5) two locations corrected them means ceilometer,...

Abstract. The Amazon biome contains more than half of the remaining tropical forests planet and has a strong impact on aspects meteorology such as planetary boundary layer (PBL). In this context, objective study was to conduct observational evaluations daily cycle height PBL during its stable (night) convective (day) phases from data that were measured and/or estimated using instruments radiosonde, sodar, ceilometer, wind profiler, lidar microwave radiometer installed in central 2014...

Abstract Tropical forests are recognized for their role in providing diverse ecosystem services (ESs), with carbon uptake the best recognized. The capacity of tropical to provide ESs is strongly linked enormous biodiversity. However, causal relationships between biodiversity and poorly understood. This may be because often translated into species richness. Here, we argue that focusing on multiple attributes biodiversity—structure, composition, function—will make clearer. In this review,...
