We examine the contribution of spectral lines and continuum emission to the EUV channels of the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) in different regions of the solar atmosphere (coronal hole, quiet Sun, active region, and flare plasma). We highlight the contribution of particular spectral lines which under certain conditions can affect the interpretation of SDO AIA data. In addition we use simultaneous observations from the Hinode Extreme-ultraviolet Imaging Spectrometer (EIS) and SDO/AIA to examine their relative intensity calibration. Good agreement is found between the two instruments for an active region observation.
