Results from LBA and a vision for future amazonian research
This chapter summarizes selected results from the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) and briefly describes a vision for future Amazonian research. The need for research on people and environment interactions is emphasized in the context of regional and global change. LBA d...

Evaluation of an ensemble of regional climate model simulations over South America driven by the ERA-Interim reanalysis: model performance and uncertainties
The capability of a set of 7 coordinated regional climate model simulations performed in the framework of the CLARIS-LPB Project in reproducing the mean climate conditions over the South American continent has been evaluated. The model simulations were forced by the ERA-Interim reanalysis dataset fo...

Phenology and seasonal ecosystem productivity in an Amazonian floodplain forest.
Several studies have explored the linkages between phenology and ecosystem productivity across the Amazon basin. However, few studies have focused on flooded forests, which correspond to c.a. 14% of the basin. In this study, we assessed the seasonality of ecosystem productivity (gross primary produc...

On the triggering mechanisms of upward lightning.
Upward lightning studies took place in Rapid City, South Dakota, USA and S. Paulo, Brazil during the summer thunderstorm seasons from 2011 to 2016. One of the main objectives of these campaigns was to evaluate and characterize the triggering of upward positive leaders from tall objects due to preced...

Why ‘blended finance’ could help transitions to sustainable landscapes: Lessons from the Unlocking Forest Finance project.
There is a momentum towards finding financing solutions for halting deforestation at the landscape level for the benefit of climate, biodiversity and delivery of ecosystem services. The Unlocking Forest Finance (UFF) project has, between 2013 and 2018, worked on the development of innovative financi...

Quantifying the aerosol effect on droplet size distribution at cloud top.
This work uses the number concentration-effective diameter phase-space to test cloud sensitivity to variations in the aerosol population characteristics, such as the aerosol size distribution, number concentration and hygroscopicity. It is based on the information from the top of a cloud simulated b...

Is there a classical inertial sublayer over the Amazon Forest?
On the basis of measurements over different surfaces, an inertial sublayer (ISL), where Monin-Obukhov Similarity Theory applies, exists above z = 3h, where h is canopy height. The roughness sublayer is within h < z < 3h. Most studies of the surface layer above forests, however, are able to probe onl...

The Brazilian Earth System Model ocean-atmosphere (BESM-OA) version 2.5: evaluation of its CMIP5 historical simulation.
The performance of the coupled ocean-atmosphere component of the Brazilian Earth System Model version 2.5 (BESM-OA2.5) was evaluated in simulating the historical period 1850-2005. After a climate model validation procedure in which the main atmospheric and oceanic variabilities were evaluated agains...

Case study for hybrid power generation combining hydro- and photovoltaic energy resources in the Brazilian semiarid region.
Hydropower is currently the primary energy resource to service the Brazilian electricity sector. However, the dry seasons in the Brazilian semiarid region have become longer due to climate variability, and they have afected the operation of hydropower plants during the last decade. Brazil has a grow...
