Evaluation of VIIRS and MODIS Thermal Emissive Band Calibration Stability Using Ground Target

open access: yesRemote Sensing, 2016
The S-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) instrument, a polar orbiting Earth remote sensing instrument built using a strong MODIS background, employs a similarly designed on-board calibrating source—a V-grooved blackbody for the Thermal

Infrared‐Guided Super‐Resolution of Remotely Sensed Passive Microwave Sea Surface Temperature

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract High‐resolution sea surface temperature (SST) is essential for weather forecasting and climate applications. Passive microwave (MW) SST offers largely cloud‐penetrating coverage but is coarse and spatially smoothed, whereas infrared (IR) SST resolves fine‐scale structures but is frequently cloud‐obscured.

Initial Stability Assessment of S-NPP VIIRS Reflective Solar Band Calibration Using Invariant Desert and Deep Convective Cloud Targets

open access: yesRemote Sensing, 2014
The latest CERES FM-5 instrument launched onboard the S-NPP spacecraft will use the VIIRS visible radiances from the NASA Land Product Evaluation and Analysis Tool Elements (PEATE) product for retrieving the cloud properties associated with its TOA flux ...

Improving AquaCrop Root‐Zone Soil Moisture by Assimilating SMAP Surface Soil Moisture

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Root‐zone soil moisture (RZSM) strongly controls crop development in process‐based crop models, yet most satellite missions observe only near‐surface moisture. We propose a framework to assimilate soil moisture active passive (SMAP) Level‐2 surface soil moisture retrievals into AquaCrop to improve RZSM over European croplands (0.1° resolution,

Inter-Comparison of S-NPP VIIRS and Aqua MODIS Thermal Emissive Bands Using Hyperspectral Infrared Sounder Measurements as a Transfer Reference

open access: yesRemote Sensing, 2016
This paper compares the calibration consistency of the spectrally-matched thermal emissive bands (TEB) between the Suomi National Polar-orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) and the Aqua Moderate Resolution ...

Environmental Filtering, Spatial Structure and Species Associations Shape Estuarine Shorebird Metacommunities Across a Continental Network

open access: yesJournal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Australian estuaries provide important non‐breeding habitat near the southern end of the East Asian–Australasian Flyway, but many are affected by coastal modification, vegetation expansion and changing hydrological conditions. We examined how habitat composition, habitat configuration, regional connectivity and residual species ...

Citizen Sailors Provide a Detailed Map of Open‐Ocean Surface Biodiversity and Help Link eDNA Data to Satellite Observations

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Characterizing open ocean biodiversity at basin scales remains challenging due to sparse sampling and limited opportunities to validate satellite‐derived estimates of plankton community composition. Through the Citizens of the Sea initiative, we deployed standardized environmental DNA (eDNA) sampling kits on 27 sailing vessels during the 2024 ...

Validation of the VIIRS ocean color

open access: yes, 2012
The Joint Polar Satellite System (JPSS) launched the Suomi National Polar-Orbiting Partnership (NPP) satellite including the Visible Infrared Sensor (VIIRS) on November 28, 2011 which has the capability to monitor ocean color properties.

Measurement of blooming effect of DMSP-OLS nighttime light data based on NPP-VIIRS data

open access: yesAnnals of GIS, 2019
Nighttime light (NTL) imagery offers important data for socio-economic research since it depicts human activities at night. Blooming effect is one of the main problems of DMSP-OLS NTL data, but the problem has been largely mitigated in NPP-VIIRS data ...

Subnational Border Reforms and Economic Activity in Africa

open access: yesOxford Bulletin of Economics and Statistics, Volume 88, Issue 5, Page 1203-1218, October 2026.
ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.
