Improving CLM5.0 Biomass and carbon exchange across the western United States Using a data assimilation system.

The Western United States is dominated by natural lands that play a critical role for carbon balance, water quality, and timber reserves. This region is also particularly vulnerable to forest mortality from drought, insect attack, and wildfires, thus requiring constant monitoring to assess ecosystem...

Assessment of extreme rainfall estimates from satellite-based: regional analysis.

Excessive rain may cause several problems for society. Understanding the behaviour of extreme rainfall and quantifying it in an assertive manner is important for whole society. The purpose of this work is to evaluate the ability of satellite precipitation products to detect the extreme rainfall over...

The Brazilian Cerrado is becoming hotter and drier.

The Brazilian Cerrado is a global biodiversity hotspot with notoriously high rates of native vegetation suppression and wildfires over the past three decades. As a result, climate change can already be detected at both local and regional scales. In this study, we used three different approaches base...

Large and increasing methane emissions from eastern Amazonia derived from satellite data, 2010-2018.

We use a global inverse model, satellite data and flask measurements to estimate methane (CH4/ emissions from South America, Brazil and the basin of the Amazon River for the period 2010-2018. We find that emissions from Brazil have risen during this period, most quickly in the eastern Amazon basin, ...

Participatory 3D model to promote intergenerational engagement for disaster risk reduction in Sao Luiz do Paraitinga, Brazil.

Purpose The objective of this study was to investigate how participatory 3D mapping can promote local intergenerational engagement for disaster risk reduction. Design/methodology/approach This investigation was carried out in the city of Sao Luiz do Paraitinga, Brazil, where a low-cost participatory...

Sensible heat flux assessment in a complex coastal-mountain urban area in the metropolitan area of Rio de Janeiro, Brazil.

Obtaining accurate estimates of surface-atmosphere energy exchanges and improved comprehension of the mechanisms generating turbulent fluxes over non-uniform landscapes are both challenging goals and essential for validating numerical weather forecasting modeling. In this work, a large-aperture scin...

Fungal tolerance to Congo red, a cell wall integrity stress, as a promising indicator of ecological niche.

Differential sensitivities to the cell wall stress caused by Congo red (CR) have been observed in many fungal species. In this study, the tolerances and sensitivities to CR was studied with an assorted collection of fungal species from three phylogenetic classes: Sordariomycetes, Dothideomycetes, an...

Policy and governance dynamics in the water-energy-food-land nexus of biofuels: Proposing a qualitative analysis model.

The production of biofuels is inextricably linked with the water-energy-food-land (WEFL) nexus. Understanding these linkages is necessary to formulate effective policies that can influence positive outcomes and contribute to the realization of long-term economic, environmental, and social goals. The...

Conserving the Cerrado and Amazon biomes of Brazil protects the soy economy from damaging warming.

In tropical regions, widespread loss of native forest and savanna vegetation is increasing extreme heat, particularly in agricultural regions. Using the case of rising extreme heat from lost forest and savanna vegetation in Brazilian Amazon and Cerrado regions, we modeled losses to soy production, t...

Epidemiology, Biodiversity, and Technological Trajectories in the Brazilian Amazon: From Malaria to COVID-19.

The Amazon biome is under severe threat due to increasing deforestation rates and loss of biodiversity and ecosystem services while sustaining a high burden of neglected tropical diseases. Approximately two thirds of this biome are located within Brazilian territory. There, socio-economic and enviro...

A model for urban biogenic CO2 fluxes: Solar-Induced Fluorescence for Modeling Urban biogenic Fluxes.

When estimating fossil fuel carbon dioxide (FFCO2) emissions from observed CO2 concentrations, the accuracy can be hampered by biogenic carbon exchanges during the growing season, even for urban areas where strong fossil fuel emissions are found. While biogenic carbon fluxes have been studied extens...

Isotopic composition of precipitation in a southeastern region of Brazil during the action of the south Atlantic convergence zone.

The use of stable isotopes of hydrogen and oxygen is a tool widely used to trace water paths along the hydrological cycle, providing support for understanding climatic conditions in different spatial scales. One of the main synoptic scale events acting in southeastern Brazil is the South Atlantic Co...
