Revisiting Trends in Greenland Ice Sheet Albedo Using the Combined MODIS and VIIRS Record

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The MODerate resolution Imaging Spectroradiometer (MODIS) instruments onboard NASA's Aqua and Terra satellites have been used to monitor trends in Greenland Ice Sheet albedo for over two decades. These satellites, however, are nearing the end of their productive lifetimes meaning that continued investigation of ice sheet albedo trends will ...

Generating global products of LAI and FPAR from SNPP-VIIRS data: theoretical background and implementation [PDF]

, 2017
Leaf area index (LAI) and fraction of photosynthetically active radiation (FPAR) absorbed by vegetation have been successfully generated from the Moderate Resolution Imaging Spectroradiometer (MODIS) data since early 2000. As the Visible Infrared Imaging

Incorporating Gas‐Phase Chemistry Into the Unified Forecast System (UFS) for Global Air Quality Applications

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract The Unified Forecast System (UFS) is a community‐based Earth modeling system designed to support operational forecasts at the National Oceanic and Atmospheric Administration (NOAA), while also facilitating the integration of research advances from the broader scientific community.

Contributions of Operational Satellites in Monitoring the Catastrophic Floodwaters Due to Hurricane Harvey

Remote Sensing, 2018
Hurricane Harvey made landfall as a Category-4 storm in the United States on 25 August 2017 in Texas, causing catastrophic flooding in the Houston metropolitan area and resulting in a total economic loss estimated to be about $125 billion.

0.25 Deg Horizontal Winds and Derived Dynamic Quantities From NOAA‐20 and Suomi‐NPP Satellite Water Vapor Soundings

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract We produced global 0.25° three‐dimensional distribution of horizontal wind vectors (or 3D winds) by tracking water vapor from the hyperspectral infrared sounders and microwave sounders aboard two polar satellites (NOAA‐20 and Suomi‐NPP) that have overlapping tracks with time separation of 50 min.

Anti‐Inflammatory Effect of 21α‐Methylmelianol In Vitro and In Vivo via NF‐κB/STAT Signaling Pathway Modulation

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
This study investigated the anti‐inflammatory effects of 21α‐methylmelianol (MMN), a tirucallane triterpenoid isolated from Melia azedarach, in lipopolysaccharide‐ stimulated RAW264.7 macrophages in vitro, and in a dextran sodium sulfate‐induced ulcerative murine colitis model in vivo. ABSTRACT Melia azedarach L., also known as the chinaberry tree, has

High Antarctic coastal productivity in polynyas revealed by considering remote sensing ice‐adjacency effects

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 945-956, December 2025.
Abstract Ocean color‐based estimates of Antarctic net primary productivity (NPP) have indicated low nearshore productivity in ice‐adjacent waters, contrasting with coupled physical–biogeochemical models. To understand this discrepancy, we assessed satellite records of polynya NPP by comparing field data with two satellite imagery datasets derived using

A Fire‐Driven Shift in Canadian Air Quality Concerns Mirrors Trends in the US

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract The summer of 2023 was the most significant wildfire and smoke season on record in Canada. Data from five different satellite instruments going back to 2001 show that Canada and most provinces and territories experienced peak visible‐wavelength aerosol optical depth and ultraviolet aerosol index values in 2023.

Limited Long‐Term Photolysis of Stratospheric Organic Aerosols With Implications for CESM Modeling

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Organic aerosol (OA) is an important constituent of the Earth's atmosphere, yet the extent of its destruction by photolysis remains an active research question. Recent laboratory studies reveal evidence for rapid short‐term photolysis for secondary OA, but the rate declines to negligible levels over time.
