The Meteorological Assimmilation Data ingest System (MADIS) provides support for data assimilation, numerical weather prediction, climate applications, and other hydrometeorological applications. MADIS is a complex system with many aspects including: ingesting, integrating, processing and transmitting both NOAA and non-NOAA surface observations across the country and ocean-based, many types of upper air soundings including balloon-borne and aircraft, and remote sensing from both ground-based and satellite systems. It has reached a point where it can now be transferred into an operational environment under NOAA Policy on Transition of Research to Operations (NAO 216-105, dated May 31, 2005). The plan is to transition MADIS to the National Weather Service's Telecommunications Operations Center (TOC) in Silver Spring, Maryland in the late 2008 timeframe. This extended abstract will discuss some of the design considerations for the transitioned system and how it will benefit NOAA customers such as the Department of Transportation through integrated, quality-controlled datasets which can be assimilated into their applications in a seamless manner.
