Surface and atmospheric patterns for early and late rainy season onset years in South America.
The biosphereatmosphere interactions associated with the rainy season onset in South America (SA) are not well understood. This study aimed to analyze the atmospheric and surface patterns associated with early, neutral, and late rainy season onset in tropical regions of SA. The following years repre...- por Portal Padrão

Income inequality and the geography of residential burglaries: A spatial model applied to Campinas.
Although income inequality has been often pointed out as an important cause of crime, it is yet unclear how spatial patterns of income in a city can explain its geography of crime. In this study, we apply a model to test the influence of income inequality on the spatial concentration of residential ...- por Portal Padrão

Ground-based and satellite measurements of solar spectral irradiances at 305 nm and 380 nm at a tropical site.
The solar radiation has been monitored through ground-based and satellite instruments all over the world for decades. This is also important for both checking and validation of satellite probing. In this work, we compare spectral irradiances at 305 nm (UV-B) and 380 nm (UV-A) from a ground-based rad...- por Portal Padrão

Tecnologias sociais na redução da vulnerabilidade às mudanças climáticas nos municípios do Ceará, Brasil.
As previsões climáticas para o Semiárido Brasileiro nesse século incluem aumento da temperatura do ar, redução das chuvas e aridização. As previsões alertam também para danos em sistemas humanos que já enfrentam uma infinidade de outras ameaças, requerendo que a vulnerabilidade nesses si...- por Portal Padrão

Investigations on concentric gravity wave sources over the brazilian equatorial region.
Observations of concentric gravity waves (CGWs) in the OH airglow emission over the Brazilian equatorial region are presented. An all-sky imager installed at Sao Joao do Cariri [7.4 degrees S, 36.5 degrees W] was used to acquire near-infrared OH images. Using over 19 years of observational data from...- por Portal Padrão

Intercomparison of planetary boundary layer heights using remote sensing retrievals and ERA5 reanalysis over central Amazonia.
The atmospheric boundary layer height ((Formula presented.)) is a key parameter in the vertical transport of mass, energy, moisture, and chemical species between the surface and the free atmosphere. There is a lack of long-term and continuous observations of (Formula presented.), however, particular...- por Portal Padrão

DETER-R: An operational near-real time tropical forest disturbance warning system based on Sentinel-1 time series analysis.
Continuous monitoring of forest disturbance on tropical forests is a fundamental tool to support proactive preservation actions and to stop further destruction of native vegetation. Currently most of the monitoring systems in operation are based on optical imagery, and thus are flaw-prone on areas w...- por Portal Padrão

The influence of diethylaniline and toluene on the streamer propagation in cyclohexane between a point-plane gap under positive impulse voltage stress.
Liquid insulation is used in high voltage equipment such as power transformers as both dielectric medium and coolant. Breakdown in liquid insulation tends to be governed either by streamer initiation under more uniform fields, or by streamer propagation under more non-uniform fields. A model streame...- por Portal Padrão
