Intercomparison of Global Solar Induced Chlorophyl Fluorescence Products

open access: yesEarth 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

open access: yesEarth 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

open access: yesGeoHealth, 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

open access: yesJournal 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.
