Uso de radar meteorológico para a avaliação das variáveis polarimétricas associadas a descargas atmosféricas no leste da Amazônia.

A compreensão da microfísica de nuvens associada a tempestades severas com grande incidência de descargas atmosféricas pode servir como base científica para o desenvolvimento de sistemas de alerta para a proteção de vidas e equipamentos expostos a céu aberto. Neste trabalho, foram avaliadas ...

State-of-the-Art and Framework for Identifying Urban Patterns by Remote Sensing Data.

The increase in the spatial resolution of satellite imagery and the greater distribution of data have enabled the use of remote sensing for urban studies. However, there is still a lack of databases and cartographic publications for cities in the Brazilian Amazon. Thus, the following questions guide...

Flood-prone areas based on physiographic indices and multi-criteria assessment for the basins of Ubatuba, on the mountainous North Coast of São Paulo State, Brazil.

The municipality of Ubatuba, São Paulo State, Southeast Brazil, is known for its strong orographic rainfall as a result of moisture fronts in the Atlantic Ocean, morphological structure, and abrupt relief of Serra do Mar. These conditioning combinations reinforce the occurrence of natural disasters...

Greening and Water Use Eciency during a period of high frequency of droughts in the Brazilian semi-arid.

A discussion that has occurred in the scientific community is that despite the increase in the frequency of droughts, the semi-arid world may be increasing the density of vegetation due to fertilization by the increase in atmospheric CO2, a phenomenon called greening. Through this study, we sought t...

A mathematical programming approach for downscaling multi-layered multi-constraint land-use models.

Land-use and land-cover change (LULCC) models are important tools for environmental policy planning. LULCC models are frequently constrained to the generation of projections at a specific resolution. However, subsequent studies or models may require finer resolutions. In this work, a downscaling met...

Spatiotemporal distribution of precipitation and its characteristics under tropical atmospheric systems of Brazil: Insights from a large sub-hourly database.

The study of rainfall properties at various spatiotemporal scales is deeply important for understanding a large range of socio-environmental processes and variables (e.g., water resources, agriculture, socio-ecosystemic services, natural risk assessment). However, such studies on rainfall characteri...

Exploring the time geography of public transport networks with the gtfs2gps package.

The creation of the General Transit Feed Specification (GTFS) in the mid-2000s provided a new data format for cities to organize and share digital information on their public transport systems. GTFS feeds store geolocated data on public transport networks, including information on routes, stops, tim...

A biomass map of the Brazilian Amazon from multisource remote sensin.

The Amazon Forest, the largest contiguous tropical forest in the world, stores a significant fraction of the carbon on land. Changes in climate and land use affect total carbon stocks, making it critical to continuously update and revise the best estimates for the region, particularly considering ch...
