Mountain Wave Forecast Model

Mountain Wave Forecast Model

A global model that forecasts mountain wave activity and turbulence potential in the troposphere and middle atmosphere.

NOGAPS-ALPHA: NOGAPS with Advanced Level Physics & High Altitude

A joint project with NRL's Codes 7532 (Monterey) and 7227 to extend the upper boundary of the Navy Operational Global Atmospheric Prediction System's (NOGAPS) global spectral forecast model to include the middle atmosphere to heights ~120 km.

CHEM2D-OPP

A fast parameterization of gas-phase ozone photochemistry for use in global numerical weather prediction and climate models.

Go Navy Ozone Assimilation!

GOATS

The Global Ozone Assimilation Testing System (GOATS) interfaces NASA's GEOS Ozone Data Assimilation System with NRL's NOGAPS-ALPHA global spectral forecast model to provide a state-of-the-art research system for studying and refining the science of operational global ozone assimilation.  See our recent work in Atmospheric Chemistry and Physics.

3DLOM simulation of breaking mountain waves over Scandinavia

Fourier-Ray Mountain Wave Models

Our latest generalization of ray methods for mountain waves.

3DLOM simulation of breaking mountain waves over Scandinavia

Nonlinear Fluid Dynamics Models

2D and 3D models of atmospheric dynamics. Principal models are:
(a) The 3DLOM (3D Lindeman Orographic Model)
(b) ARW, the Advanced Research WRF (Weather Research and Forecast Model)
Gravity-wave Regional Or Global RAy Tracer

Gravity Wave Regional or Global Ray Tracer

A model that simulates the global or region propagation and amplitude evolution of gravity waves in the lower and middle atmosphere using spatial ray-tracing techniques.
