The NOAA Meteorological Assimilation Data Ingest System (MADIS) is a NOAA Research system, developed at the Earth System Research Laboratory (ESRL), that serves the meteorological community by supporting observation collection integration, quality control, and distribution of thousands of NOAA and non-NOAA observations, including nearly 30,000 surface stations from local, state, and federal agencies, and private networks, as well as upper-air datasets including multi-agency profiler and aircraft observations. The mesonet database includes Road Weather Information System observations from state Departments of Transportation, as well as real-time observations from the Remote Automated Weather Stations network, the Cooperative Mesonets in the Western U.S. network, the WeatherBug network operated by AWS Convergence Technologies, Inc., and many others. MADIS receives these observations in different formats, units, and time stamps, and provides them in a single uniform database. Additionally, MADIS supplies data providers with quality control and station monitoring information to assist in their maintenance activities and to enhance and promote the mutual benefits of public/private data sharing. Organizations receiving MADIS data feeds include National Weather Service (NWS) forecast offices, the NWS National Centers for Environmental Prediction, the National Center for Atmospheric Research, and many major universities and commercial weather businesses.

In 2007, the NOAA Research Council and NOAA Transition Board rated MADIS as one of NOAA's highest priority research-to-operations transition projects. Overall plans for the transition include the implementation of MADIS real-time capabilities at the NWS Telecommunication Operations Center and the transfer of existing MADIS saved datasets and future archive responsibilities to the NESDIS National Climatic Data Center. ESRL will remain as the primary MADIS Research and Development organization, and will head the Coordination and Outreach Team (COT), which is responsible for coordinating all requirements related to users and customers, data providers, metadata, and data formats. The COT team will also be responsible for conducting workshops with NOAA's customers to ascertain new requirements for the future enhancement of the transitioned MADIS system. This poster will provide a status update on the existing MADIS system, a general overview of NOAA's transition plans, and will also allow MADIS customers an opportunity to begin the process of interacting with, and providing requirements, to the ESRL MADIS team on desired future MADIS capabilities.
