Reducing numerical errors and resolution-dependence of atmospheric physics
Numerical approaches to improving atmospheric dynamics for multiscale parameterizations
Parameterizing ocean eddies with scale-aware ocean Mesoscale Eddy Parameterization (MEP)
Validation, verification and uncertainty quantification (VVUQ) methods are critical tools for the development of multiscale models.
Lightning strikes and wildfires could increase by ~50% over this century causing significant change in the continent’s atmospheric chemistry.
Using CAM version 5 (CAM5) physics significantly improves cloud scaling at different grid resolutions.
An experimentation strategy for investigating sensitivities in fast components of atmospheric general circulation models.
The spectral-bin microphysics (SBM) method reproduced observed convection intensity well and found that mass flux is very sensitive to different microphysical schemes for tropical convection.
Collaborative work with the SciDAC Institute FASTMath has delivered an algorithmically scalable preconditioner to solve shallow water equations within the CAM-SE.
