Calibration of the SMAP Soil Moisture Retrieval Algorithm to Reduce Bias Over the Amazon Rainforest

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Soil moisture (SM) is crucial for the Earth's ecosystem, impacting climate and vegetation health. Obtaining in situ observations of SM is labor-intensive and complex, particularly in remote and densely vegetated regions like the Amazon rainforest.

Self-amplified Amazon forest loss due to vegetation-atmosphere feedbacks

Nature Communications, 2017
Relatively little is understood about seasonal effect of climate change on the Amazon rainforest. Here, the authors show that Amazon forest loss in response to dry-season intensification during the last glacial period was likely self-amplified by ...

Resilience analysis in the Amazon rainforests

, 2023
Here are the main codes and data for a paper to be published as: Wang, H., Ciais, P., Sitch, S., et al. Anthropogenic disturbance exacerbates resilience loss in the Amazon rainforests (Under review). We share codes for transparency and to demonstrate the application of SHAP analysis using machine learning. The raw data formatted as .csv are required to

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, EarlyView.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

The Application of Telemedicine in Surgery

Med Research, EarlyView.
This figure provides an overview of the content presented in this article. Telemedicine is integrated throughout the entire surgical workflow, with distinct applications across the preoperative, intraoperative, and postoperative phases. These applications are enabled by a suite of supporting technologies, while the associated implementation challenges ...

Unexpected seasonality in quantity and composition of Amazon rainforest air reactivity

Nature Communications, 2016
The degree to which biogenic volatile organic compounds released by the Amazon canopy impact oxidation capacity remains uncertain. Here, the authors evaluate the vertical distribution of total hydroxyl radical reactivity and individual trace gases in the

Correlation between Amazon deforestation and rainfall patterns in the Iguaçu River basin (Paraná, Brazil) [PDF]

Brazilian Journal of Biology
The Amazon Rainforest plays a crucial role in regulating the South American hydrological cycle, particularly through moisture transport driven by the Low-Level Jets (LLJs), which connect the Amazon region to southern Brazil.

Sensitivity of the Amazon biome to high resolution climate change projections [PDF]

Acta Amazonica, 2016
: Despite the reduction in deforestation rate in recent years, the impact of global warming by itself can cause changes in vegetation cover. The objective of this work was to investigate the possible changes on the major Brazilian biome, the Amazon ...

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...
