Abstract: The article focuses on the development of EMAG2v3QT, a revised Earth Magnetic Anomaly Grid designed to address significant data gaps in the Qinghai-Xizang Plateau region. EMAG2v3QT integrates the existing EMAG2 version 3 (EMAG2v3) global magnetic anomaly data with newly processed aeromagnetic survey data from the China Geological Survey, filling previous coverage voids and improving spatial resolution to 2 arc minutes at 4 km altitude. The updated grid employs data continuation, filtering, and merging techniques to ensure consistency and smooth transitions between datasets, enabling more accurate analyses of lithospheric magnetic structures in this tectonically important area. EMAG2v3QT is publicly available for scientific research and aims to enhance geophysical and geological investigations of the Qinghai-Xizang Plateau. [Extracted from the article]
