We present simulated coronal emission pictures of some case-study solar active regions, including NOAA-designated regions
8210 and 8038. The simulated emissions are calculated from a 3-d temperature, density, and magnetic field model of the
corona based on first principles. The method involves a static energy balance along individual coronal loops, with the
heating term taken from a given coronal heating theory. The predicted emissions can be compared with observed X-ray and UV
satellite images. By comparing the predictions of various heating theories with observations, we can determine constraints
on the probable mechanisms of coronal heating. The model is also useful for a variety of other applications, such as testing
of coronal magnetic field extrapolation techniques, calculations of wave propagation and shock phenomena, and testing
assumptions about the spatial distribution of heating along loops. This work was supported by a DoD/AFOSR MURI grant,
"Understanding Magnetic Eruptions and their Interplanetary Consequences."
