The Air Pollution Emission Experiments and Policy analysis (APEEP) model is an integrated assessment model that links emissions of air pollution to exposures, physical effects, and monetary damages in the contiguous United States.  The model and its updated version, AP2, have been used in many peer-reviewed publications (see Current CV). A new, updated version of the model (AP3) is now available soon (early 2018).The primary distinctions between the model years are the data in the model: emissions, population, mortality rates, for example.
