Intercomparison of Global Solar Induced Chlorophyl Fluorescence Products

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of Sun‐Induced Chlorophyll Fluorescence (SIF) provide a powerful means to assess terrestrial photosynthesis at regional to global scales, yet major SIF products differ in retrieval strategy, radiometric stability, and sensitivity to environmental conditions.

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

Low‐Income, Minority‐Serving Public Schools in Southern California Have Disproportionately High Surface Temperatures

GeoHealth, Volume 10, Issue 9, September 2026.
Abstract Extensive evidence demonstrates that people from minority backgrounds often face unequal exposure to extreme heat and have less access to green space that can provide cooling relief. What is less clear is whether these inequities extend to students on school playgrounds, where high temperatures can affect physical health, social and emotional ...

Bayesian Analysis of Infragravity Edge Waves

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Infragravity (IG) waves (periods nominally 25–250 s) are generated in shallow water by nonlinear difference‐frequency interactions between shorter period (nominally 4–25 s) incident sea‐swell waves. Previous studies show strong IG reflection from the beach face and detectable IG energy in alongshore‐propagating edge waves.

Direct Assimilation of Satellite Visible and Near‐Infrared Radiances to Improve Aerosol Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Existing satellite‐based aerosol data assimilation approaches mostly rely on assimilating retrieved aerosol products, which suffer from inconsistencies between retrieval assumptions and model representations, as well as uncertainties in the retrieved aerosol parameters.

Assimilation of Atmospheric CO2 Concentration in the ORCHIDEE Land Surface Model: Exploring the Added Value of Explicit Forest Regrowth Representation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The land absorbs a large proportion of human‐induced carbon emissions, yet the spatial distribution of this carbon sink remains uncertain. Land surface models (LSMs) and atmospheric inversions often diverge on the spatial distribution of carbon sink, with models generally underestimating the northern land sink (above 30°N).

Process‐Based Model Parameters for Post‐Fire Snow Hydrology: Looking Beyond Snow Albedo and Vegetation

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Wildfires fundamentally alter snow accumulation and melt dynamics by modifying forest canopy structure, snow albedo, and snowpack physical properties. Despite the growing body of work on fire impacts on snow, few studies have used physically based models to simulate post‐fire changes, and none have examined the global parameter sensitivities ...
