The AMIE procedure is an optimally constrained, weighted least-squares fit of electric potential distribution to diverse types of atmospheric observations. Knowledge of these distributions is important in many areas of magnetospheric, ionospheric, and thermospheric physics.
CISM is a National Science Foundation/Science and Technology Center program to develop a complete Sun-Earth model. The focus is on modeling the magnetosphere using the LFM
, the Thermosphere and Ionosphere using TIEGCM
and a coupled version of these codes, called CMIT
There are several boundary layers to take into consideration in space physics near the Earth. The solar wind generates a shock at the outter boundary of the magnetosphere. The inner magnetosphere affects auroral activity at the ionosphere boundary, which drives certain processes at the thermosphere. In order to better understand these interactions, we have created the CMIT model.
CEDAR is the dominant national and international research program in terrestrial aeronomy. Scientifically, CEDAR is devoted to the characterization and understanding of the atmosphere above ~60 km, with emphasis on the energetic and dynamic processes that determine the basic composition and structure of the atmosphere.
DOCFM is an NCAR/CfA collaboration that is funded by AFOSR to model the global coronal magnetic field using magnetometric and other observations, with the goal of improving space weather forecasts of magnetic orientation within coronal mass ejections.
FORWARD is a suite of IDL and fortran codes that calculates simulated coronal polarization signals from numerical and analytical models of the corona. The images generated by the code are directly comparable to the CoMP
data and can be used as guidelines to look for specific magnetic morphologies in the observational data.
The GSWM solves the linearized and extended Navier-Stokes equations for steady-state global temperature and wind perturbations. GSWM may be used to calculate an "unforced" planetary wave response for a specified period and zonal wavenumber, or the thermally-driven response for either a diurnal or semidiurnal atmospheric tide.
The LFM Code is an integrated simulation model for the global magnetosphere-ionosphere system. The heart of the model is a time-dependent, ideal MHD calculation of the state of the magnetosphere.
The NCAR TGCM's are three-dimensional, time-dependent models of the EARTH's neutral upper atmosphere. The model uses a finite differencing technique to obtain a self-consistent solution for the coupled, nonlinear equations of hydrodynamics, thermodynamics, continuity of the neutral gas and for the coupling between the dynamics and the composition.
The Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM-X) is a comprehensive numerical model, spanning the range of altitude from the Earth’s surface to the upper thermosphere. The development of the model is inter-divisional collaboration that unifies certain aspects of the upper atmospheric modeling of HAO
, the middle atmosphere modeling of ACD
, and the tropospheric modeling of CGD
, using the NCAR Community Earth System Model (CESM
) as a common numerical framework.
