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...

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...
