At this website, we present recent model results that illustrate the thermal, compositional and dynamical responses of the upper atmospheres of Venus, Earth, and Mars to solar EUV-UV flux variability making use of the Venus VTGCM, the Earth TIEGCM, and the Mars MTGCM three-dimensional models. Each of these models has been developed and exercised at the National Center for Atmospheric Research (NCAR) using its CRAY computers.
