Atmospheric Imaging Assembly (AIA) will be one of the instruments on the Solar Dynamics Observatory (SDO). It will image the solar transition region and corona in multiple EUV and UV wavelengths simultaneously, using four aligned telescopes. Hence, AIA will be capable of high-cadence, spatially-resolved temperature discrimination of solar plasmas. We present an algorithm for using AIA observations to produce differential emission measure (DEM) reconstructions, and investigate the quality of fit for different models and the effects of random and systematic errors.
