Potencial eólico no Rio Grande do Sul distribuição estatística dos ventos na região central do estado.
Este estudo procura identificar o melhor modelo estatístico para modelar a intermitência dos ventos e avalia ocomportamento anual e sazonal do regime de ventos. Os dados anemométricos foram coletados na plataforma do Projeto SONDA em operação desde 2004 no Observatório Espacial do Sul em São ...

Combining sattelite sensing and census data to quantify agricultural land use change in the Brazilian Amazon.
As pasture and cropland have replaced forest cover in the Brazilian Amazon, the creation of spatial explicit time series of land use is an important concern in modeling land change. Despite much progress in mapping deforestation using satellite remotely sensed data, little is known about the distrib...

Remote wind stress influence on mean sea level in a subtropical coastal region.
The purpose of this study was to assess the relative influence of remote wind stress on mean sea level (MSL) variations in the coastal region of Cananeia (Sao Paulo State, Southern Brazil) during the period from 1/1/1955 to 12/31/1993. An optimized low-pass Thompson filter for the study area, and sp...

Changes in vegetation cover in reforested areas in the State of São Paulo, Brazil and the implication for landslide processes.
In Brazil, plantations of exotic species such as Eucalyptus have expanded substantially in recent years, due in large part to the great demand for cellulose and wood. The combination of the steep slopes in some of these regions, such as the municipalities located close to the Serra do Mar and Serra ...

Methane airborne measurements and comparison to global models during BARCA.
Tropical regions, especially the Amazon region, account for large emissions of methane (CH 4). Here, we present CH 4 observations from two airborne campaigns conducted within the BARCA (Balano Atmosférico Regional de Carbono na Amaznia) project in the Amazon basin in November 2008 (end of the dry s...

Frequency distributions of some parameters of negative downward lightning flashes based on accurate-stroke-count studies.
This paper presents some parameters of negative cloud-to-ground lightning flashes in terms of frequency distribution. All data are based on so-called accurate-stroke-count studies from different climatological regions in the world and were already published in the literature with the exception of ou...

Carbon monoxide and related trace gases and aerosols over the Amazon Basin during the wet and dry seasons.
We present the results of airborne measurements of carbon monoxide (CO) and aerosol particle number concentration (CN) made during the Balan double dagger o Atmosf,rico Regional de Carbono na Amazonia (BARCA) program. The primary goal of BARCA is to address the question of basin-scale sources and si...

Ozone sounding in the metropolitan area os São Paulo, Brazil: wet and dry season campanigns of 2006.
In the Metropolitan Area of São Paulo (MASP), located in southeastern Brazil, surface ozone concentrations are often well above the national air quality standards. In this experimental study, we attempted to characterize the vertical profile of atmospheric ozone and transport of the ozone plume in ...

Modeling the spatial and temporal heterogeneity of deforestation-driven carbon emissions: the INPE-EM framework applied to the Brazilian Amazon.
We present a generic spatially explicit modeling framework to estimate carbon emissions from deforestation (INPE-EM). The framework incorporates the temporal dynamics related to the deforestation process and accounts for the biophysical and socioeconomic heterogeneity of the region under study. We b...
