Climategate: the role of the social sciences
As has been widely documented, lavishly funded media campaigns by political and financial elites and corporations with vested interests against climate policy are a central instigator of the climate backlash and a threat to democratic processes. However, it would behoove the environmental coalition,...- por Portal Padrão

Anatomy of dissent: a cultural analysis of climate skepticism
Based on findings from ethnographic analysis of U.S. climate scientists, this article identifies largely unrecognized sociocultural dimensions underpinning differences in scientists' perceptions of anthropogenic climate change. It argues that culturally laden tensions among scientists have influence...- por Portal Padrão

Integração de imagens NOAA/AVHRR: Rede de cooperação para monitoramento nacional da safra de soja
An early assessment of national crop development conditions while the plants are still in the fields is highly needed to calculate correctly projections for decision-making and policies related to government planning andfood security. The aim of this study was to evaluate the suitability of NOAA /AV...- por Portal Padrão

Inhalable particulate matter characterization in a medium-sized urban region in Brazil (São José dos Campos Town) – Part I: morphology
In this study, the concentration and morphological characteristics of inhalable particulate material (PM10) were evaluated and associated with climatic conditions. The mean annual concentration was 11.0 µg m−3, varying between 0,647 µg m−3 and 36.8 µg m−3. Wind speed has a higher influence ...- por Portal Padrão

Variability of air-sea CO2 fluxes and dissolved inorganic carbon distribution in the Atlantic Basin: a coupled model analysis
The biogeochemical dynamics of carbon in the ocean is a subject of fundamental interest to environmental studies. In this context, we have implemented a ten year run of the Brazilian Earth System Coupled Ocean-Atmosphere Model (BESM-OA2.3) integrated with TOPAZ biogeochemical model for the Atlantic ...- por Portal Padrão

Updated analyses of temperature and precipitation extreme indices since the beginning of the twentieth century: the HadEX2 dataset
In this study, we present the collation and analysis of the gridded land-based dataset of indices of temperature and precipitation extremes: HadEX2. Indices were calculated based on station data using a consistent approach recommended by the World Meteorological Organization (WMO) Expert Team on Cli...- por Portal Padrão

Calibration and validation of the Integrated Biosphere Simulator (IBIS) for Brazilian Semi-Arid Region
The reliability of predictions from climate and weather models is linked to an adequate representation of the land surface processes. To evaluate performance and to improve predictions, land surface models are calibrated against observed data. Despite an extensive literature describing methods of la...- por Portal Padrão

Impactos das mudanças de cobertura vegetal nos processos de superfície na região semiárida do Brasil
A cobertura vegetal da superfície continental tem sido consideravelmente alterada pelas atividades humanas, principalmente através da conversão em grande escala da vegetação natural por áreas de cultivos e pastagens. Essas mudanças na cobertura da superfície podem alterar o clima regional e ...- por Portal Padrão

Visible channel development during the initial breakdown of a natural negative cloud-to-ground flash
GPS time synchronized high-speed video records (at 4000 frames per second) and electric field waveforms are discussed for one stepped leader of a negative cloud-to-ground flash whose initial development becomes visible above cloud base. The leader emerges from the opaque region of the thundercloud a...- por Portal Padrão

Validação de dados termopluviométricos obtidos via sensoriamento remoto para o Estado de São Paulo
Dados termopluviométricos são utilizados em diversos estudos. Contudo, a escassez de dados resultante da baixa densidade de estações meteorológicas é um problema frequentemente encontrado. Com isto, a utilização de dados estimados por satélites tem-se mostrado importante para regiões nas q...- por Portal Padrão
