Twenty Years of Satellite Observations Reveal a Shift in the Diurnal Trend of Dust Optical Depth Over West Africa

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract West Africa is the largest global source of mineral dust, with significant impacts on climate, air quality, and biogeochemical cycles. While temporal variations in dust loading from daily to interannual scales are well studied, the long‐term evolution of the diurnal cycle itself is often overlooked.

Re‐Evaluating Inherited SIF Anomaly Detection Methods for the 2024 Amazon Drought: A 3D Convolutional Autoencoder Approach

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract In the past decade, the Amazon has experienced multiple severe droughts, raising critical questions about how vegetation stress can be detected using remote sensing indicators such as Solar‐Induced Chlorophyll Fluorescence (SIF). In this study, we compare two anomaly detection approaches applied to TROPOSIF data. First a classical pixel wise z‐

Satellite‐Based Global Assessment of Solar Resource Stability

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite spatial smoothing complicates comparisons of solar variability between gridded products and point measurements. We introduce the Stability Deviation Index (SDI), a bounded composite of solar intensity and intraday variability. Applied independently to 69 BSRN stations and co‐located CERES grid cells, SDI shows strong cross‐platform ...
