Background

About the Data System (Purposes, Audience):

The audience, at present, is INTERNAL EPA analysts, application builders, and data integrators. AIRQuest was constructed as a true data warehouse, built to integrate data from various source data systems, to enable complete air quality analyses from a single system. AIRQuest harvests data from AQS, NEI, and AIRNow, integrating that data spatially and temporally. It also features datasets outside of EPA that are useful for analysis -- meteorological, census, etc.

History:

AIRQuest evolved from an OAQPS internal need for access to integrated data, without having to comb through a variety of source data systems. The vision was to develop a single source of high-quality, integrated, and up-to-date data, thereby allowing analysts to do their jobs without having to visit a myriad of sources and perform their own integration. Another important concept was that of "one answer", i.e. a warehouse codified business processes such that each analysis can be done consistently and with reproducible results.
