High-resolution aboveground carbon changes in the Brazilian Amazon using repeated airborne lidar.
The Brazilian Amazon is a hotspot of deforestation and forest degradation caused by logging, fire, and deforestation-associated fragmentation and edge effects. While the extent of deforestation and associated carbon losses are relatively well known, the quantification of the carbon losses caused by ...- por Portal Padrão

Quantifying carbon loss at forests degraded by logging with repeated airborne Lidar data in the Brazilian Amazon.
Forest degradation is a major issue and a key component of tropical forests and carbon emissions. In this study, we use repeated Airborne Laser Scanning (ALS) data to quantify carbon losses in degraded forests due to logging at the Mato Grosso state rainforests. We identified logged areas using Plan...- por Portal Padrão

Avaliação das previsões de altíssima resolução em região de topografia complexa.
O modelo regional Eta, desenvolvido pelo INPE, tem como intuito complementar as previsões numéricas de tempo e clima, elaboradas através de modelos de circulação geral da atmosfera. O modelo apresenta uma alta resolução espacial, capaz de simular eventos de precipitação em pequenas escalas ...- por Portal Padrão

Degradação da terra nos biomas Cerrado e Caatinga no contexto dos ODS.
Eventos extremos de calor estão se tornando mais frequentes no globo terrestre, e com eles, diversos impactos são causados na sociedade. No Brasil, as ondas de calor estão mais intensas, abrangentes e de mais duração. Para monitorar e prever esses eventos extremos, é de suma importância possu...- por Portal Padrão

Using Routine Aircraft Profiles of CO2 and COS to Evaluate the Changing Carbon Cycle in Amazonia.
A large fraction of the terrestrial carbon sink is located in the tropics, and it is thought that much of the year-to-year variability in the global carbon sink is due to effects of climate and human influences on productivity, respiration, and disturbance in the tropics. There is a pressing need fo...- por Portal Padrão

Strategic dam-planning for climate change mitigation and biodiversity conservation in the Magdalena River basin.
Climate change and biodiversity loss are two of the most pressing environmental challenges confronting humanity in the 21st century. Strategies for mitigating climate change are often assumed to provide co-benefits towards biodiversity conservation, but can also incur strong biodiversity costs. Hydr...- por Portal Padrão

First leader spectra observation associated with TGFs production at the Telescope Array Surface Detector.
In this work we report the first observation of time-resolved leader spectra associated with Terrestrial Gamma Ray Flashes (TGFs) at the Telescope Array Surface Detector (TASD). The TASD is a ground-based surface detector primarily designed to observe ultra-high energy cosmic rays. The TASD site is ...- por Portal Padrão

Amazon deforestation combined high atmospheric CO2 concentration, a new state of South America climate.
The land cover change in the Amazon basin has been a high-impact subject in climate studies, especially those that evaluated the hydrological issues not only locally but also regionally. However, the increase of atmospheric carbon dioxide may lead to different behavior in the biosphere-atmosphere co...- por Portal Padrão
