Reduced Vegetation Uptake During the Extreme 2023 Drought Turns the Amazon Into a Weak Carbon Source

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract In 2023, the biogeographic Amazon experienced temperature anomalies of 1.5°C above the 1991–2020 average from September to November. These conditions were driven by high sea surface temperature in the Atlantic and Pacific oceans, together with reduced moisture advection from the Atlantic, causing large vapor pressure and water deficits in the ...

Towards estimating land evaporation at field scales using GLEAM [PDF]

, 2018
The evaporation of water from land into the atmosphere is a key component of the hydrological cycle. Accurate estimates of this flux are essential for proper water management and irrigation scheduling.

Implementing a Plant Hydraulics Parameterization in the Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC) v.1.4

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Drought conditions cause stress to terrestrial ecosystems and make their accurate representation in models challenging. The Canadian LAnd Surface Scheme Including biogeochemical Cycles (CLASSIC) employs an empirical approach to link soil moisture stress with stomatal conductance. Such approaches typically perform poorly during drought.

Assessing Global Surface Water Inundation Dynamics Using Combined Satellite Information from SMAP, AMSR2 and Landsat [PDF]

, 2018
A method to assess global land surface water (fw) inundation dynamics was developed by exploiting the enhanced fw sensitivity of L-band (1.4 GHz) passive microwave observations from the Soil Moisture Active Passive (SMAP) mission.

Climate‐Driven Hydraulic Traits Shift in Natural and Planted Forests: Patterns, Drivers, and Future Acclimation

Earth's Future, Volume 14, Issue 1, January 2026.
Abstract Plants modify their functional traits in response to changing environmental conditions under climate change. However, it remains unclear whether tree planting alters patterns and acclimation of hydraulic traits across spatial scales. Here, we compiled a site‐level data set of hydraulic traits in natural (NF) and planted forests (PF) to examine

Quantitative assessment of various proxies for downscaling coarse-resolution VOD products over the contiguous United States

International Journal of Applied Earth Observations and Geoinformation
Vegetation Optical Depth (VOD), a vegetation parameter that quantifies the extinction effect of microwaves penetrating the canopy, plays a crucial role in global-scale biomass monitoring and climate change research.

Precipitation and temperature drive woody vegetation dynamics in the grasslands of sub‐Saharan Africa

Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 740-754, December 2025.
Identifying the drivers of ecosystem dynamics, and their spatiotemporal variation, is critical in the face of global change. Sub‐Saharan African grasslands support biodiversity, carbon storage, and livelihoods, yet the drivers of change remain poorly understood.

Parameter Estimation in Land Surface Models: Challenges and Opportunities With Data Assimilation and Machine Learning

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Accurately predicting terrestrial ecosystem responses to climate change over long‐timescales is crucial for addressing global challenges. This relies on mechanistic modeling of ecosystem processes through land surface models (LSMs). Despite their importance, LSMs face significant uncertainties due to poorly constrained parameters, especially ...

Evaluation of optical and microwave-derived vegetation indices for monitoring aboveground biomass over China

Geo-spatial Information Science
The microwave-derived vegetation optical depth (VOD) products were used to monitor aboveground biomass (AGB) at regional to global scales, but the ability of VOD to monitor AGB in China is uncertain.
