Electric field waveforms of M components in negative and positive ground flashes: A comparative analysis.
There has been some discussion concerning the nature of luminosity pulses observed during the continuing currents of positive cloud-to-ground flashes. It still undefined whether or not these pulses can be considered M components when compared to similar events observed in negative flashes. In the pr...

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...
