What is a simple way to atmospherically correct Landsat 8 data using Erdas 9.3 or ArcGIS 9.3?

Most of the data available from Landsat has already been corrected to some degree. See the documents here: landsat.usgs.gov/documents/provisional_l8sr_product_guide.pdf– Chris StrotherCommented Jun 23, 2015 at 19:40

I would advise using the dark object subtraction (DOS) method for atmospheric correction. Essentially, you find a dark object in your scene--such as a deep, dark water body--where you know there is no reflectance. Any brightness values associated with the dark object in your scene are therefore likely the result of atmospheric effects. These values can then be subtracted from the other pixel values.
