Soil texture and chemical characteristics along an elevation range in the coastal Atlantic Forest of Southeast Brazil.
We analyzed soils under forest across an elevation range (100 m, Lowland Forest, 400 m, Submontane Forest, and 1000 m, Montane Forest) in the Atlantic Rainforest of São Paulo State, Brazil. We hypothesized that soil nutrient content would increase with elevation in the surface mineral soil as a res...

Precipitation in the Amazon and its relationship with moisture transport and tropical Pacific and Atlantic SST from the CMIP5 simulation.
Studies on numerical modeling in Amazonia show that the models fail to capture important aspects of climate variability in this region and it is important to understand the reasons that cause this drawback. Here, we study how the general circulation 5 models of the Coupled Model Intercomparison Proj...

Potential land availability for agricultural expansion in the Brazilian Amazon.
The Amazon hosts one of the largest stocks of arable land in the world. However, little is known about the available extent of agricultural land in conformity with legal, agronomical and environmental requirements. This study aims to identify and quantify potentially available areas for agricultural...

Comments on “the tropospheric land-sea warming contrast as the driver of tropical sea level pressure changes”.
In their paper "The tropospheric land-sea warming contrast as the driver of tropical sea level pressure changes,'' Bayr and Dommenget proposed a simple model of temperature-driven air redistribution to quantify the ratio between changes of sea level pressure p(s) and mean tropospheric temperature T-...

Hybrid color segmentation method using a customized nonlinear similarity function.
Image segmentation is a fundamental step in several image processing tasks. It is a process where an image is divided into its constituent regions guided by a similarity criterion. One very interesting image segmentation method is the color structure code (CSC), which combines simultaneously split-a...

Integrating forest cover change with census data: drivers and contexts from Bolivia and the lao PDR.
The aim of this paper is to explore possible links between forest cover change and characteristics of social-ecological systems at sub-national scale based mainly on census data. We assessed relationships between population density, poverty, ethnicity, accessibility and forest cover change during th...

Characterising Brazilian biomass burning emissions using WRF-Chem with MOSAIC sectional aerosol.
The South American Biomass Burning Analysis (SAMBBA) field campaign took detailed in situ flight measurements of aerosol during the 2012 dry season to characterise biomass burning aerosol and improve understanding of its impacts on weather and climate. Developments have been made to the Weather Rese...

Day-to-day differences in the characterization of lightning observed by multiple high-speed cameras.
This study aims to analyze how the visible parameters of cloud-to-ground discharges such as the flash multiplicity and duration, the interstroke interval, the continuing current duration and the number of ground contacts per flash vary between observations conducted on different days. Several author...

Experiences with a socio-environmental modeling course.
In a social-environmental modeling course, students need to learn complementary skills that include the conceptualisation of a model, different modeling paradigms, computer programming, and the process of rigorously converting ideas and data into a computational program using a given toolkit. Such t...
