Landsat-8/9 Atmospheric Correction Reliability Using Scene Statistics

Remote Sensing
Landsat data correction using the Land Surface Reflectance Code (LaSRC) has been proposed as the basis for the atmospheric correction of smallsats. While atmospheric correction can enhance smallsat data, the Landsat/LaSRC pathway delays output and may ...

A Harmonized Landsat–Sentinel‐2 Burned‐Area Product for the Pantanal (2014–2024), Based on Multitemporal Composites

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
This work presents AQM‐HLS, a harmonized burned‐area dataset for the Pantanal covering 2014–2024. Landsat‐8/9 and Sentinel‐2 imagery were integrated into multitemporal NBR composites and classified using Random Forest. The dataset captures fire‐scar dynamics, delivering accurate 30‐m burned‐area maps suitable for long‐term monitoring and environmental ...

Water quality assessment of Loktak Lake, Manipur using Landsat 9 imagery

Water Practice & Technology
ABSTRACT The role of freshwater lakes in providing water resources and supporting ecosystems is essential. Monitoring water quality using remote sensing (RS) technologies is crucial for sustainable management practices. A study on Loktak Lake was done using RS algorithms to predict post-monsoon water quality.

Optimizing Wind Power Plant Locations: A GIS‐Based Approach With Interval Type‐2 Fuzzy Risk Deviation Performance Index

Wind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT This study develops an integrated GIS and multicriteria decision making (MCDM) approach supported by the Interval Type‐2 Fuzzy Risk Deviation Performance Index (IT2F‐RDPI) method to assess the wind energy potential in Diyarbakır Province. Fifteen criteria, including wind speed, slope, land use, elevation, soil structure, and proximity to ...

Satellite‐Based Assessment of Methane Emissions From the Darvaza Gas Crater

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Methane is a potent greenhouse gas, and the Darvaza crater in Turkmenistan is a rare, persistent emitter. There are uncertainties regarding its formation date (either 1963 or 1971), fire ignition, and the fire's influence on methane release. Using historical Landsat imagery, we reconstruct the fire history, identifying that combustion began ...

Pansharpening largely preserves the normalized difference vegetation index: a multi-sensor comparison with PRISMA, Landsat 9, and field spectroscopy

Frontiers in Remote Sensing
Pansharpening is widely used to increase the spatial resolution of satellite imagery, yet its effects on vegetation indices derived from hyperspectral sensors remain poorly quantified.

Windblown Diatoms for Reconstructing Westerly Wind Variability in the South Atlantic Sector of the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Southern Hemisphere westerly winds are important drivers of Antarctic and sub‐Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide valuable tools to extend environmental records. Here we present a novel wind study based on the use of windblown

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Water Quality Monitoring Using Landsat 8 OLI in Pleasant Bay, Massachusetts, USA

Remote Sensing
Water quality monitoring is essential to assess and manage anthropogenic eutrophication, especially for coastal estuaries in heavily populated areas. Current monitoring techniques rely on in situ sampling, which can be expensive and limited in spatial ...
