The Moderate Resolution Imaging Spectroradiometer (MODIS): land remote sensing for global change research

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 1998
The first Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is planned for launch by NASA in 1998. This instrument will provide a new and improved capability for terrestrial satellite remote sensing aimed at meeting the needs of global change research.

Variability of Particulate Organic Carbon Stock in the South China Sea With Reference to Profile Structures

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Accurate characterization of particulate organic carbon (POC) stock is essential for understanding regional biological pump processes, yet the roles of vertical structure and integration depth in regulating POC stock variability remain unclear in marginal seas. Using a performance‐evaluated 3D POC data set, we assessed POC stock changes in the

How to determine the leaf area index (LAI) of forests: A comparison of forest inventory versus satellite-driven estimates

open access: yesForest Ecosystems
Leaf area index (LAI) is a key measure of forest stand physiology and biomass production, and is essential within ecosystem modeling. There are two common approaches to obtaining LAI: (i) terrestrial forest inventory-based “bottom–up”, and (ii) satellite-

Southern Ocean Clear‐Sky Brightening From Sea Spray Aerosol Increase Drives Departure From Hemispheric Albedo Symmetry

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Observations reveal significant negative trends in reflected shortwave radiation over the 21st century. The global‐mean darkening is primarily driven by clouds, while the global‐mean atmospheric clear‐sky signal is near zero due to offsetting trends in the two hemispheres.

A Cloud Screening Preprocessing Framework for GOCI‐II Aerosol Optical Depth: Development and Impact on Retrieval Errors

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Accurate retrieval of satellite‐derived aerosol optical depth (AOD) is critical for air quality forecasting, especially when AOD is assimilated into models. However, if retrieval errors in the satellite‐derived AOD are not corrected or characterized, they can lead to false analysis increments and ultimately degrade the quality of data ...

Mapping 30-m cotton areas based on an automatic sample selection and machine learning method using Landsat and MODIS images

open access: yesGeo-spatial Information Science
Cotton is one of the most significant cash crops in the world, and it is also the main source of natural fiber for textiles. It is crucial for cotton management to identify the spatiotemporal distribution of cotton planting areas timely and accurately on

Correlated Modes of Spatiotemporal Variations Between Biomass Burning Aerosols and Tropospheric Temperature Over the Indian Region

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Biomass burning aerosols influence atmospheric temperatures by absorbing solar radiation, thereby altering the contrast between day and night temperatures. This study investigates the correlation between these aerosols and day‐night (D‐N) temperature changes over India by applying principal component analysis (PCA) in long‐term (2003–2021 ...
