Análise Episódica do Downburst do dia quatorze de fevereiro de 2018, no município do Rio de Janeiro.
Desde o século XVIII o Rio de Janeiro é afetado por eventos extremos de precipitação, os quais acarretam uma série de transtornos no espaço urbano, por meio de inundações e movimentos de massa. Dentre inúmeros eventos, o ocorrido no dia quatorze de fevereiro de 2018, possui características...

Climate projections of precipitation and temperature in cities from ABC Paulista, in the Metropolitan Region of São Paulo-Brazil.
Cities are increasingly vulnerable to climate change's impacts and poorly adapted to extreme variability. This study aimed to evaluate climate projections of air temperature and precipitation in seven cities in the Metropolitan Region of São Paulo that correspond to the Greater ABC Paulista. We use...

Idealized hydrodynamical numerical model dataset with no-river runoff at the western tropical North Atlantic.
The western tropical North Atlantic (WTNA) is a very complex region, with the influence of intense western boundary currents in connection with equatorial zonal currents, important atmospheric forcings (e.g Intertropical Convergence Zone), mesoscale activities (e.g NBC rings), and the worlds largest...

Computational methods of EEG signals analysis for Alzheimer’s disease classification.
Computational analysis of electroencephalographic (EEG) signals have shown promising results in detecting brain disorders, such as Alzheimer's disease (AD). AD is a progressive neurological illness that causes neuron cells degeneration, resulting in cognitive impairment. While there is no cure for A...

Estimating public transport emissions from General Transit Feed Specification data.
This paper introduces the gtfs2emis model, a bottom-up method available as an R package to estimate emissions of public transport systems. The method uses General Transit Feed Specification (GTFS) data, a standard format for public transport data widely adopted worldwide, which makes the method easi...

Socio-environmental vulnerability to drought conditions and land degradation: an assessment in two northeastern Brazilian river basins.
over the past few decades, a significant amount of agricultural land has been lost due to soil degradation/desertification. in addition, the increasing frequency of extreme events, such as intense droughts and forest fires, has negatively impacted various ecosystem services. two of the main brazilia...

Genetic viability and habitat suitability of the critically endangered southern muriqui (Brachyteles arachnoides) in the Atlantic Forest’s fragmented landscapes under land use and climate change scenarios.
The joint effects of climate change and landscape fragmentation to the genetic viability of isolated populations has barely been addressed for the Atlantic Forest fauna. Therefore, this work explored the potential habitat suitability for the southern muriqui (Brachyteles arachnoides), by modeling cl...

Moisture origins of the Amazon carbon source region.
The southeastern Amazon has recently been shown to be a net carbon source, which is partly caused by drying conditions. Drying depends on a number of factors, one of which is the land cover at the locations where the moisture has originated as evaporation. Here we assess for the first time the origi...

A decentralized approach to model national and global food and land use systems.
The achievement of several sustainable development goals and the Paris Climate Agreement depends on rapid progress towards sustainable food and land systems in all countries. We have built a flexible, collaborative modeling framework to foster the development of national pathways by local research t...

The role of ecosystem transpiration in creating alternate moisture regimes by influencing atmospheric moisture convergence.
The terrestrial water cycle links the soil and atmosphere moisture reservoirs through four fluxes: precipitation, evaporation, runoff, and atmospheric moisture convergence (net import of water vapor to balance runoff). Each of these processes is essential for sustaining human and ecosystem well-bein...

Multiple controls on carbon dioxide sequestration in the beagle channel (Southern Patagonia) in early fall.
Subpolar coastal waters are key hotspots in the global carbon cycle. However, the small-scale distribution of partial pressure of carbon dioxide (pCO2) in these environments and the physical and biological controls underlying this variability are still poorly understood. Here, we examine simultaneou...

Land use and green crime: assessing the edge effect.
Green crimes are violations of environmental laws that aim to protect human well-being, natural resources, and ecosystems. Brazil has recorded an increase in green crimes in recent years. In this study, we used Spatial Durbin and other regression models to analyze the relationship between land use a...
