The IWDW has been fully supported by multiple federal and state agencies, with assistance from WESTAR-WRAP, since its creation through the 3SAQS Pilot Study. The IWDW provides air quality data, photochemical grid modeling products, and analysis tools to support various air quality applications. Available datasets include emissions inventories, meteorological data, air quality modeling platforms, and monitoring data.
