Subnational Border Reforms and Economic Activity in Africa

Oxford 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.

Atmospheric Correction of GOCI Using Quasi-Synchronous VIIRS Data in Highly Turbid Coastal Waters

Remote Sensing, 2019
The Geostationary Ocean Color Imager (GOCI) sensor, with high temporal and spatial resolution (eight images per day at an interval of 1 hour, 500 m), is the world’s first geostationary ocean color satellite sensor. GOCI provides good data for ocean

Utilization of the Suomi National Polar-Orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band for Arctic Ship Tracking and Fisheries Management [PDF]

Remote Sensing, 2015
Maritime ships operating on-board illumination at night appear as point sources of light to highly sensitive low-light imagers on-board environmental satellites. Unlike city lights or lights from offshore gas platforms, whose locations remain stationary from one night to the next, lights from ships typically are ephemeral.

Derivation of a MODIS-compatible enhanced vegetation index from visible infrared imaging radiometer suite spectral reflectances using vegetation isoline equations [PDF]

, 2013
We developed a unique methodology that spectrally translates the enhanced vegetation index (EVI) across sensors for data continuity based on vegetation isoline equations and derived a moderate resolution imaging spectroradiometer (MODIS)-compatible EVI ...

Wildfire Smoke Along Colorado's Front Range in 2020: An Evaluation of PM2.5 Monitor Spacing and Smoke Forecasts

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The 2020 wildfires caused widespread elevated fine particulate matter (PM2.5) concentrations across the western U.S. The Colorado Front Range experienced multiple smoke episodes from nearby fires and fires hundreds of kilometers away. Multiple days (88 total) with elevated PM2.5 along the Front Range occurred in 2020 between July and October ...

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.
