Mapping Quartz and Feldspar Areal Abundance and Grain Sizes Using Integrated VTIR Data
AGU Advances, Volume 7, Issue 3, June 2026.Abstract Mineral dust is sourced from arid regions around the globe, and its composition impacts regional and global environments by affecting radiation balance, cloud formation, nutrient deposition, and snowmelt. As such, mineral dust plays a key role in Earth's energy and biogeochemical budgets.
