iSEAM: Improving the Blooming Effect Adjustment for DMSP-OLS Nighttime Light Images by Considering Spatial Heterogeneity of Blooming Distance

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The longest archive makes DMSP-OLS nighttime light (NTL) images unparalleled in relevant time series studies. However, these studies have been constrained by the blooming effect.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

Journal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Delineating urban, suburban and rural areas using Landsat and DMSP-OLS night-time images Case Study of Hyderabad, India [PDF]

, 2011
The number and size of urban settlements are increasing in all the continents of the world at a rapid pace. Urban sprawl is associated not only with changes in landcover and area, but also ecological, climate and social transformations.

Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures

Journal of Regional Science, EarlyView.
ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities.
