Soil macrofauna and water-related functions in patches of regenerating Atlantic Forest in Brazil.
The Atlantic Forest is the most threatened Brazilian biome, with less than 10% of its original surface cover remaining. Thus, several programs of payment for ecosystem services have been developed in this biome focusing on revegetation of degraded areas. Forest regeneration promotes the development ...

Multiscale analysis of drought, heatwaves, and compound events in the Brazilian Pantanal in 2019–2021.
In this study, a comprehensive multiscale analysis of compounding drought-heat events in the Pantanal region is presented. The goal is to assess the multiscale nature of drought and determine whether the combined effects of drought and heatwaves, as driving factors, are more relevant than the effect...

The South American Tropopause Aerosol Layer (SATAL).
The presence of an aerosol layer in the upper troposphere/lower stratosphere (UT/ LS) in South America was identified with the Modern-Era Retrospective Analysis for Research and Applications version 2 (MERRA-2). This layer, which we shall refer to as the South American tropopause aerosol layer (SATA...

An attribution study of very intense rainfall events in Eastern Northeast Brazil.
Severe floods and landslides in Eastern Northeast Brazil in May 2022 led to severe impacts with human losses and material damage. These disasters were a direct consequence of extremely heavy rainfall days. A rapid attribution study was performed to assess the role of anthropogenic climate change in ...

Evaluation of Soil Microbial and Enzymatic Activity in Ecosystems in a Coastal Region of Brazil.
The enormous soil carbon pool stored by mangroves depends upon microbial respiratory activities and enzymes associated with carbon breakdown in soils. Our hypothesis is that increased microbial activity leads to elevated carbon breakdown. To prove this, we measured microbial respiratory and enzyme a...

Two decades of clear-cutting threats in the Brazilian Amazonian protected areas around the Jirau, Santo Antônio, and Belo Monte large dams.
Deforestation rates in the Amazon have markedly increased in the last few years, affecting non-protected and protected areas (PAs). Brazil is a hotspot of Protected Area Downgrading, Downsizing, and Degazettement (PADDD) events, with most events associated with infrastructure projects. Despite the t...

Urban Heat Island Assessment in the Northeastern State Capitals in Brazil Using Sentinel-3 SLSTR Satellite Data.
The lack of a solid methodology defining urban and non-urban areas has hindered accurately estimating the Surface Urban Heat Island (SUHI). This study addresses this issue by using the official national urban areas limit together with a surrounding areas classification to define three different refe...

Partitioning of water vapor and CO 2 fluxes and underlying water use efficiency evaluation in a Brazilian seasonally dry tropical forest (Caatinga) using the Fluxpart model.
The Fluxpart partitioning model was employed to assess transpiration, photosynthesis and evaporation, respiration based exclusively through high-frequency eddy covariance (EC) data. The model was implemented across three sites with two vegetation cover conditions (dense and sparse) during the drough...

DeepWealth: A generalizable open-source deep learning framework using satellite images for well-being estimation.
Measuring socioeconomic indices at the scale of regions or countries is required in various contexts, in particular to inform public policies. The use of Deep Learning (DL) and Earth Observation (EO) data is becoming increasingly common to estimate specific variables like societal wealth. This paper...
