Analysis of Fire Hotspot Numbers, Fire Radiative Power and Air Pollutant Concentrations in the Legal Amazonia Between 2016 and 2021.
Over the past few years, the Amazonia region has experienced a notable increase in fire occurrences, primarily attributed to agricultural management and territorial possession. This increase has, in turn, led to as rise in atmospheric concentrations of pollutants. This chapter presents an observatio...

Drivers of aboveground biomass change in recently burned forests of western Amazonia
Wildfire substantially affects Amazonian forest ecosystems, including a large and persistent loss of aboveground biomass. This study investigates the drivers of changes in aboveground biomass in recently burned forests in western Amazonia. We collected soil samples in eight terra firme forest plots ...

Influence of geomagnetic disturbances on myocardial infarctions in women and men from Brazil.
Background Understanding the role of space weather, specifically Geomagnetic Disturbances (GMDs) caused by solar activity, on health outcomes is unclear. One emerging link includes the impact of space weather on myocardial infarctions (MI). In this study we examined the correlation between MI and GM...

FLAME 1.0: a novel approach for modelling burned area in the Brazilian biomes using the maximum entropy concept.
As fire seasons in Brazil lengthen and intensify, the need to enhance fire simulations and to comprehend fire drivers becomes crucial. Yet determining what drives burning in different Brazilian biomes is a major challenge, with a highly uncertain relationship between drivers and fire. Finding ways t...
