NOAA's MADIS Reaches Major Milestone

The Meteorological Assimilation Data Ingest System (MADIS) wrapped up FY2010 with a noteworthy accomplishment: achieving Initial Operating Capability (IOC) on 30 Sep 2010. Demand for finer scale meteorological services increasingly requires higher resolution observations to initialize and evaluate both weather and climate models. In response to this demand, ESRL's Global Systems Division (GSD) developed MADIS to collect, integrate, quality control, and distribute observations from NOAA and non-NOAA organizations. MADIS leverages partnerships with international agencies; federal, state, and local agencies; universities; volunteer networks; and the private sector (e.g. airlines, railroads, and buses) to integrate observations with those of NOAA to provide a finer density, higher frequency observational database. MADIS currently provides data from over 63,000 surface stations, gathered from more than 180 data providers, and makes these available to over 1,000 users.

By achieving IOC, MADIS now runs operationally in real time at the National Weather Service (NWS) with a distributed architecture consisting of ingest and distribution services at the Telecommunications Operations Center with processing performed at the National Centers for Environmental Prediction's Central Operations. MADIS also runs quasi-operationally in a research test environment at ESRL/GSD, where new advances in technology are developed and tested prior to technology transfer into NWS operations. This IOC milestone marks a gigantic leap forward for NWS and NOAA missions.

By integrating other-agency and private-network observations with NOAA observations, and making them easily accessible, MADIS carries out NOAA's mission goal to "Serve Society's Needs for Weather and Water Information" while also enhancing and promoting the mutual benefits of public/private data sharing.
