Some pitfalls in statistical downscaling of future climate
Statistical downscaling is generally successful and used widely to refine projections of future climate, though in some circumstances it can lead to highly erroneous results.- publication PDF

Adapting the MPAS dynamical core for applications extending into the thermosphere
To extend the nonhydrostatic global Model for Prediction Across Scales (MPAS) for deep-atmosphere (geospace) applications, we have modified the model equations and numerics to...- publication PDF
