Development and implementation of a new biomass burning emissions injection height scheme (BBEIH v1.0) for the GEOS-Chem model (v9-01-01).
Biomass burning is a significant source of trace gases and aerosols to the atmosphere, and the evolution of these species depends acutely on where they are injected into the atmosphere. GEOS-Chem is a chemical transport model driven by assimilated meteorological data that is used to probe a variety ...

Season‐based rainfall–runoff modelling using the probability‐ distributed model (PDM) for large basins in southeastern Brazil.
Southeastern Brazil is characterized by seasonal rainfall variability. This can have a great social, economic, and environmental impact due to both excessive and deficient water availability. During 2014 and 2015, the region experienced one of the most severe droughts since 1960. The resulting water...

Tools for communicating agricultural drought over the Brazilian Semiarid using the soil moisture index.
Soil moisture over the Brazilian semiarid region is presented in different visualizations that highlight spatial, temporal and short-term agricultural risk. The analysis used the Soil Moisture Index (SMI), which is based on a normalization of soil moisture by field capacity and wilting point. The in...

Distribution modelling and multi-scale landscape connectivity highlight important areas for the conservation of savannah elephants.
Habitat connectivity is the milestone towards species' long-term persistence, especially considering impacts of climate change and human activities. Here, we examined the potential implications of climate change and human pressure on connectivity among habitat patches, aiming to identify priority ar...

Environmental and biological controls on seasonal patterns of isoprene above a rain forest in central Amazonia.
The Amazon rain forest is a major global isoprene source, but little is known about its seasonal ambient concentration patterns. To investigate the environmental and phenological controls over isoprene seasonality, we measured isoprene mixing ratios, concurrent meteorological data, and leaf area ind...

Individual tree crown delineation in a highly diverse tropical forest using very high resolution satellite images.
Mapping tropical tree species at landscape scales to provide information for ecologists and forest managers is a new challenge for the remote sensing community. For this purpose, detection and delineation of individual tree crowns (ITCs) is a prerequisite. Here, we present a new method of automatic ...

Compliance to Brazil’s forest code will not protect biodiversity and ecosystem services.
In striking contrast to heartening events in the adjacent Amazon, Brazil's Cerrado biome has seen continued deforestation over the past decade. Though approved in 2012, no study evaluated the impacts of new Brazilian Forest Code (FC) revision on biodiversity and ecosystem services. Here, we report t...

The Brazilian Earth System Model version 2.5: evaluation of its CMIP5 historical simulation.
The performance of the coupled ocean-atmosphere component of the Brazilian Earth System Model version 2.5 (BESM-OA2.5) simulating the historical period 1850-2005 is evaluated. Following climate model validation procedure, in which the atmospheric and oceanic main variabilities are validated against ...
