Atmospheric and Health Effects Framework Model Estimating Ultraviolet Radiation-induced Health Effects

The EPA uses the Atmospheric and Health Effects Framework Model (AHEF) to estimate ultraviolet (UV)-induced health effects that may result from stratospheric ozone depletion.

The AHEF combines satellite ozone measurements with projected emissions of ozone depleting substances (ODS) to estimate future ozone concentrations, and associated changes in UV and health effects (i.e., melanoma and non-melanoma incidence and mortality, and cataract incidence). The AHEF is used to :
  • estimate the change in health effects resulting from various ODS policy scenarios, 
  • perform sensitivity analyses, 
  • compare and evaluate results generated by similar models, and
  • examine the public health and atmospheric impacts of:
    • aviation,
    • methyl bromide use,
    • National Ambient Air Quality Standards (NAAQS), and
    • halon decommissioning strategies.
