High resolution lightning density maps to study elevation effects at microscale.
Lightning location systems have evolved over the years in both location accuracy and detection efficiency. For the Brazilian integrated lightning detection network (RINDAT), the mean location accuracy has increased along the years as the network was expanded and the performance and sensibility were ...

Hydrological response of the Amazon basin to drought events of 1997/98, 2005 and 2010.
While there is an increasing understanding on forest response to severe droughts episodes recently occurred in Amazon region (e.g. tree mortality rates, live biomass, CO2 exchanges and forest resilience), there has been not so many works on the hydrological response of the region to rainfall anomali...

The Amazon floodplain ecosystem: large-scale dynamics, climate change impacts and implications for biodiversity.
The Amazon floodplain ecosystem links large-scale climatic phenomena to the lives of animals (including people), plants, and other organisms that live within it. The floodplain is subject to seasonal changes in water level that can reach up to 16m, as it aggregates rainfall inputs from the entire Am...

Scenarios for the Amazonia 2050: combining emission reductions and social development.
Deforestation in Amazonia has decreased significantly in the last five years, from around 27,772 km2 in 2004 to around 6,000 km2 in 2010. This decrease has been attributed to a net of governmental/civil society actions, and commodities markets related factors. In spite of this, there is an enormous ...

Multi-scale participatory scenario methods as a tool of local population empowerment: case studies in the Brazilian Amazonia.
We are investigating how multi-scale participatory scenario methods can contribute to the process of consolidation of the mosaic of diverse territorial units which constitute the Brazilian Amazonia nowadays. Today, indigenous lands, conservation units and settlements represent more than 60% of the A...

Resolution of the sprite polarity paradox: the role of halos.
This study revisits the sprite polarity paradox, first manifest by observations that exceptional cloud-to-ground flashes with negative polarity generally did not produce detectable sprites. The paradox is here resolved by the Transient Luminous Event (TLE) known as the halo, which on account of its ...

Evapotranspiration of deforested areas in central and southwestern Amazonia.
Considering the high rates of evapotranspiration of Amazonian forests, understanding the impacts of deforestation on water loss rates is important for assessing those impacts on a regional and global scale. This paper quantifies evapotranspiration rates in two different pasture sites in Amazonia and...

Anodic and cathodic pre-treatment effects on BDD surface to deposit copper nanoparticles applied to nitrate reduction.
The influence of anodic and cathodic pre-treatment on boron doped diamond (BDD) surface for copper (Cu) electrodeposition was studied to assess Cu particle consolidation on BDD electrode. These modified electrodes were applied to study the nitrate electrochemical reduction process. The obtained resu...
