Fine‐Scale Estimation of Urban Biogenic CO2 Fluxes: A Novel Framework Integrating Multiple Versions of Vegetation Photosynthesis and Respiration Models and In Situ Measurements

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Estimating biogenic CO2 fluxes is essential to quantify urban anthropogenic emissions, yet urban vegetation heterogeneity presents a significant challenge to making accurate estimations. We have developed an hourly temporal, 10‐m spatial resolution biogenic CO2 flux estimation framework based on the Vegetation Photosynthesis and Respiration ...

Machine Learning Calibration of Groundwater Table Depth in ELM: Impact on Land Surface Hydrology and Land‐Atmosphere Fluxes

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Accurate representation of groundwater table depth (GWTD) is crucial for simulating hydrological cycling in Earth system models (ESM). Nevertheless, there is a notable gap in the literature regarding the validation of GWTD simulations in ESMs and their subsequent impact on downstream hydrological components. This study explores the calibration

Contrasting Parametric Sensitivities in Two Global Vegetation Models Using Parameter Perturbation Ensembles

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Uncertainty in land model projections remains high and the roles of parametric and structural uncertainty are difficult to disentangle. To compare parametric sensitivity across model structures we present two parameter perturbation ensembles using the Community Land Model (CLM) operating in satellite phenology mode.

Systematic Benchmarking of Climate Models: Methodologies, Applications, and New Directions

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract As climate models become increasingly complex, there is a growing need to comprehensively and systematically assess model performance with respect to observations. Given the increasing number and diversity of climate model simulations in use, the community has moved beyond simple model intercomparison and toward developing methods capable of ...

Observation‐Constrained Physical Snow Water Equivalent Simulations Using a Physics‐Guided Machine Learning Approach

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Estimating daily snow water equivalent (SWE) is critical for hydrological and climate applications, yet physical models often struggle to represent SWE, especially its interannual anomalies. In this study, we developed a hybrid physics‐guided machine learning (ML) model (hybrid model), by augmenting the Community Land Model 4.0 SWE simulations

Satellite Solutions: Facing Chlorophyll‐a Retrieval in Small Mountain Lakes in the Sierra Nevada, Spain

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract National and international regulations enforce monitoring programmes of water quality to guide management actions of inland water ecosystems. Our study evaluates the effect of spectral and spatial resolutions on the estimation of chlorophyll‐a concentrations in mountain lakes, and derives implications for addressing the adjacency effect, which

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

Functional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...
