Fonte ou semidouro? uma revisão sobre os fluxos de CO2 na plataforma continental brasileira.
Studies of global carbon balance estimates are still incipient in the oceans of the Southern Hemisphere, mainly in coastal areas and continental shelf. Even in Brazil, despite its continental proportion coastline, there is still a great inconsistency in studies on the marine carbonate system and CO2...

Hydrological Model Performance in the Verde River Basin, Minas Gerais, Brazil.
In hydrological modelling, it is important to consider the uncertainties related to a models structures and parameters when different hydrological models are used to represent a system. Therefore, an adequate analysis of daily discharge forecasts that takes into account the performance of hydrologic...

Re-appraisal of the global climatic role of natural forests for improved climate projections and policies.
Along with the accumulation of atmospheric greenhouse gases, particularly carbon dioxide, the loss of primary forests and other natural ecosystems is a major disruption of the Earth's system and is causing global concern. Quantifying planetary warming from carbon emissions, global climate models hig...

Water Lifting and Outflow Gain of Kinetic Energy in Tropical Cyclones.
While water lifting plays a recognized role in the global atmospheric power budget, estimates for this role in tropical cyclones vary from no effect to a major reduction in storm intensity. To better assess this impact, here we consider the work output of an infinitely narrow thermodynamic cycle wit...

Influence of sample preparation methods on FTIR spectra for taxonomic identification of tropical trees in the Atlantic forest.
The Atlantic forest is one of the world's major tropical biomes due to its rich biodiversity. Its vast diversity of plant species poses challenges in floristic surveys. Fourier transform infrared spectroscopy (FTIR) enables rapid and residue-free data collection, providing diverse applications in or...

Burned area occurrence in agrarian reform settlement projects in the Matopiba region, Brazil.
Wildfires have been causing negative effects on ecosystems and rural communities. Among rural communities, the agrarian reform settlement projects have registered fires resulting from agricultural management inside and outside their areas. In this context, our objective was to analyze 821 settlement...

Multiple regional climate model projections to assess building thermal performance in Brazil: Understanding the uncertainty.
Understanding the trends and uncertainties in Building Energy Simulation (BES) performance indicators under future climate conditions is crucial for mitigating issues such as overheating and power outages. To address this, we generated a set of weather files for all 27 state capitals in Brazil, cons...

Impacts on South America moisture transport under Amazon deforestation and 2 °C global warming.
The increase in greenhouse gasses (GHG) anthropogenic emissions and deforestation over the last decades have led to many chemical and physical changes in the climate system, affecting the atmosphere's energy and water balance. A process that could be affected is the Amazonian moisture transport in t...

RECCAP2 Future Component: Consistency and Potential for Regional Assessment to Constrain Global Projections.
Projections of future carbon sinks and stocks are important because they show how the world's ecosystems will respond to elevated CO2 and changes in climate. Moreover, they are crucial to inform policy decisions around emissions reductions to stay within the global warming levels identified by the P...

Sink or carbon source? how the Opuntia cactus agroecosystem interacts in the use of carbon, nutrients and radiation in the Brazilian semi-arid region.
Anthropogenic disturbances directly influence environmental processes and increase the concentration of carbon (C) in the atmosphere. Here, we compare the differences in the seasonality of the balance of carbon, energy, and radiation, as well as seek to identify the interrelationships between these ...

Changes in atmospheric circulation and evapotranspiration are reducing rainfall in the Brazilian Cerrado.
Here we analyze the trends of rainfall and the frequency of rainy days over the Brazilian Cerrado between 1960 and 2021 in four distinct periods according to the seasonal patterns over the region. We also evaluated trends in evapotranspiration, atmospheric pressure, winds, and atmospheric humidity o...
