BUILT-UP AREA DYNAMICS IN “PRE- AND DURING BOKO HARAM CONFLICTS” IN MONGUNO LOCAL GOVERNMENT AREA OF BORNO STATE, NIGERIA

This study examines how snow-covered surfaces affect air pollution in Northeast China. Using numerical simulations, we explore chlorine-related chemical reactions that generate reactive species, enhancing fine particles and ozone. Results show that snow-surface reactions drive nighttime pollutant accumulation and notably improve model performance, providing new insights into how snow and surface chemistry influence regional air quality.
