Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Snow Cover Mapping for Mountainous Areas by Fusion of MODIS L1B and Geographic Data Based on Stacked Denoising Auto-Encoders

Computers, Materials & Continua, 2018
Snow cover plays an important role in meteorological and hydrological researches. However, the accuracies of currently available snow cover products are significantly lower in mountainous areas than in plains, due to the serious snow/cloud confusion problem caused by high altitude and complex topography.

The Amazon River‐Breeze Circulation Limits Detection of Aerosol‐Cloud Interactions in Warm Clouds

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Increased aerosol concentrations can brighten low‐level clouds and extend their lifetimes, but aerosol–cloud interactions (ACI) remain highly uncertain and difficult to quantify. We show that part of this uncertainty is caused by topographical influences on clouds, that is, those arising from land–water contrasts.

Snow-Covered Area Retrieval from Himawari–8 AHI Imagery of the Tibetan Plateau

Remote Sensing, 2019
Daily snow-covered area retrieval using the imagery in solar reflective bands often encounters extensive data gaps caused by cloud obscuration. With the inception of geostationary satellites carrying advanced multispectral imagers of high temporal ...

Modeling Upper Ocean Ecosystem Dynamics in Response to Interannual Sea‐Ice Variability in the Western Antarctic Peninsula

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract In the Western Antarctic Peninsula (WAP), marine plankton dynamics are tightly linked to the interannual variability in environmental conditions, including phenological shifts in sea‐ice seasonality. To explore these linkages, we use a 1‐dimensional vertical ocean‐ice‐ecosystem model (KPP‐Eco‐Ice, or KEI) that simulates physical and ecosystem ...

Spatiotemporal snow cover characterization and its linkage with climate change over the Chenab river basin, western Himalayas

GIScience & Remote Sensing, 2020
Monitoring of snow cover variability is crucial because it is closely linked with mountain water resources, ecosystems, and climate change. For this, moderate-resolution imaging spectroradiometer (MODIS) daily snow cover products (SCPs, version 6) were ...

Evaluating the climate effects of mid-1800s deforestation in New England, USA, using a Weather, Research, and Forecasting (WRF) Model Multi-Physics Ensemble [PDF]

, 2016
The New England region of the northeastern United States has a land use history characterized by forest clearing for agriculture and other uses during European colonization and subsequent reforestation following widespread farm abandonment. Despite these

Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...

Snow Cover Maps from MODIS Images at 250 m Resolution, Part 1: Algorithm Description

Remote Sensing, 2013
A new algorithm for snow cover monitoring at 250 m resolution based on Moderate Resolution Imaging Spectroradiometer (MODIS) images is presented. In contrast to the 500 m resolution MODIS snow products of NASA (MOD10 and MYD10), the main goal was to ...

Influence of Tibetan Plateau Snow Cover on ENSO Variability via the Dust‐Iron Fertilization

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The El Niño–Southern Oscillation (ENSO) and Tibetan Plateau, as key drivers of Earth's climate system, exert bidirectional controls that complicate causal attribution. Here, we integrate satellite‐derived Tibetan Plateau snow cover (TPSC) with causal inference to establish TPSC‐ENSO conversion factor.
