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 ...

Phytoplankton Bloom Changes During Three Regime Shifts Derived From Sea Ice Concentration in the Ross Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Sea Ice Concentration (SIC) plays an important role in the Antarctic polynyas, especially where biological interactions through changes in chlorophyll‐a concentration (CHL) phenology are concerned. To specifically understand how much SIC change affects CHL in the Ross Sea polynya (RSP), the regime shift index (RSI) was applied to the SIC ...

A high-resolution emission inventory of air pollutants from primary crop residue burning over Northern India based on VIIRS thermal anomalies.

Environmental Pollution, 2020
Emissions from the crop residue burning adversely affect the regional and global air quality including public health. In this study, a district-wise comprehensive emission inventory of key pollutants (PM2.5, PM10, CO, CO2, SO2, NOx, N2O, NH3, CH4, NMVOC,

Winter‐to‐Winter Sea Surface Temperature Anomaly Reemergence in the Yellow Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The reemergence of winter sea surface temperature anomalies (SSTAs) serves as an effective oceanic memory mechanism, linking winter SSTs across consecutive years in mid‐latitude deep oceans. However, its existence and potential role in modulating SSTA variability in continental shelf seas have remained largely unexplored.

Sensitivity of VIIRS polarization measurements [PDF]

SPIE Proceedings, 2010
The design of an optical system typically involves a sensitivity analysis where the various lens parameters, such as lens spacing and curvatures, to name two parameters, are (slightly) varied to see what, if any, effect this has on the performance and to establish manufacturing tolerances.

Double‐Peaked Hyperspectral Features at 710 and 800 nm for Monitoring Coastal Chlorophyll‐α Concentrations From Space

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract The concentration of chlorophyll‐α $\alpha $ has been estimated from sea color, primarily based on the reflectance ratio between the blue and green spectral bands in multiband images obtained by satellite optical sensors. However, this method is only effective in open, clear water and cannot be reliably applied to shallow coastal waters.

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.

Arctic High Resolution Sea‐Ice Forecast System on a Heterogeneous Many‐Core Computing Platform

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This study develops an ensemble forecast system for Arctic sea ice with a horizontal resolution of ∼2 km to resolve linear kinematic features (LKFs). The system is designed to run operationally on the Sunway computing architecture, which employs many‐core processors with a distinct programming logic.
