ENSO-driven reverse coupling in interannual variability of pantropical water availability and global atmospheric CO2 growth rate

Environmental Research Letters, 2020
The large interannual variability of global atmospheric CO _2 growth rate originates primarily from variation in carbon dioxide (CO _2 ) uptake of pantropical terrestrial ecosystems, which covaries with the El Niño–Southern Oscillation (ENSO) modulated ...

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Securing Water in a Changing Climate: A Transient Solar Desalination Model for the Sundarbans, Bangladesh

Energy Science &Engineering, EarlyView.
This graphical abstract presents a solar‐powered reverse osmosis (RO) system for the Sundarbans, Bangladesh. Mechanistic modeling reveals a critical seasonal mismatch: during the monsoon, feed water salinity peaks (24.8 ppt) while solar irradiance drops significantly.

Influence of Salinity and Temperature Gradients on the Variability of the North Brazil Undercurrent

Frontiers in Marine Science, 2021
The North Brazil Undercurrent (NBUC) is a narrow (<1°) northward western boundary current in the tropical South Atlantic Ocean. It carries a large volume of water (>16 Sv) and plays an important role in the Atlantic Meridional Overturning ...

Farm‐Level Greenhouse Gas Balance of Commercial Coffee Production in Minas Gerais, Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Coffee production is considered a potential contributor to climate change mitigation due to its perennial biomass and carbon storage capacity. However, empirical assessments of greenhouse gas (GHG) balances at the farm level remain limited for commercial coffee systems.

Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

No constraint on long-term tropical land carbon-climate feedback uncertainties from interannual variability

Communications Earth & Environment
Unraveling drivers of the interannual variability of tropical land carbon cycle is critical for understanding land carbon-climate feedbacks. Here we utilize two generations of factorial model experiments to show that interannual variability of tropical ...

Oceanic control of Northeast Pacific hurricane activity at interannual timescales

Environmental Research Letters, 2013
Sea surface temperature (SST) is not the only oceanic parameter that can play a key role in the interannual variability of Northeast Pacific hurricane activity.

Characterising Vento Norte Downslope Windstorms and Their Thermal Impacts in Southern Brazil

International Journal of Climatology, EarlyView.
Using 20 years of hourly INMET observations in Santa Maria (southern Brazil), we identify 189 Vento Norte (VNOR) downslope windstorms, ~72% in winter, marked by abrupt warming, drying and strong northerly gusts. Across five biometeorological indices (TEFW, TDI, THI, HDI, Humidex), VNOR hours consistently show significantly higher thermal discomfort ...
