Deforestation in the Amazon Biome has become more evident through the "arc of deforestation." Protected Areas (APs; Abbreviation in Portuguese) in the Amazon play numerous environmental services in this region, notably the preservation of sources within the Purus and Madeira River interfluve, the conservation of habitats for plant and animal specie...
Remote sensing data has helped to carry out forest inventories by providing information about objects without direct contact. However, planning forest management activities requires reliable information, and inventory is the basis for planning the use of forest resources. Notably, the most used variables for forest inventories are the height and di...

Brazil is the country with the highest social inequality in South America. This socioeconomic disparity reflects not only on the families' income but also on their spatial localization in the city, as well as on the urban design. These urban environments can alter the urban microclimate, and consequently, interfere in dwellers' thermal comfort. Thi...

Many efforts have been made in recent years to better understand the elements driving climate changes. Along with greenhouse gases, some recent studies have analyzed the impacts of land use change on the temperature at local, regional and even global scale. Most of these studies focused on the impact of changing vegetation cover by cropland and oth...
Density maps are one of the most common and powerful lightning data applications, and they are more efficient the more detailed they are. When working with CG lightning data from lightning location systems, some aspects must be included in the analysis to overcome network performance variations. Two parameters are typically used to evaluate system...
Several systems to track and nowcast thunderstorms are available, most of them using algorithms based on radar and satellite information (among the most common are TITAN, WDSS-II etc.). Most of theses systems are able to assimilate lightning data available from lightning location systems (LLSs) to improve the resulting information. On the other han...
One of the most interesting attributes of Lightning Location Systems (LLSs) data is that they can be analyzed in several ways according to the objectives of the study. However, the quality of the data is governed by the system performance and has some limitations when analyzed at different temporal/spatial scales, and these limitations will depend...
