Research notebooks and scripts from my work in atmospheric science, climate modeling, and extreme weather analysis
This repository contains code, notebooks, and scripts from my undergraduate and graduate research — spanning Ghana, West Africa, Madagascar, Kentucky, and the U.S. Projects range from operational heatwave diagnostics and precipitation climatology to CMIP6 model validation and severe weather analysis.
