The Tracking and Analysis Framework (TAF) is an integrated modeling framework developed to assess, inform, and guide U.S. regulatory policies on emissions of precursors to acid rain.

The TAF model is a collaborative effort of over 30 scientists from 11 institutions. All model components have been created with Analytica^®, a modeling and simulation tool. The primary sponsor of TAF is National Acid Precipitation Assessment Program (NAPAP), the primary funder of TAF is the Department of Energy (DoE).
