The Intermountain West Data Warehouse (IWDW) was created through joint efforts of Federal agencies (Land Managers and EPA), and State Air Quality Program Managers to address regional scale modeling analysis and planning needs. The IWDW contains monitoring, emissions, and air quality modeling data and analysis tools to support regulatory, research, and academic applications. As one of the participants, the State of Colorado uses the data from the IWDW for a variety of regulatory efforts including modeling efforts to support the development of State Implementation Plans and for air quality research efforts such as the Front Range Air Pollution and Photochemistry Experiment (FRAPPE). The emissions inventories developed for the IWDW are highly detailed and much more suitable to local modeling efforts than the EPA National Emission Inventory. Here we present an overview of the 2011 statewide IWDW emissions inventory for Colorado and examine historic trends in statewide inventories used for modeling, planning and analysis. The IWDW 2011 inventory should prove highly useful to modeling, regulatory, research and policy needs for participating agencies.
