MADIS Assists the Linked Environments for Atmospheric Discovery (LEAD) Project
From the November 7, 2003 LEAD newsletter:
A highly positive development has occurred in relation to the Meteorological Assimilation Data Ingest System (MADIS) database at FSL, which makes value-added surface and upper-air data available for the purpose of improving weather forecasting, via support for data assimilation, NWP, and other applications. In addition to the previous forms of data access to the MADIS database via ftp and LDM, FSL is now making MADIS data available via OPeNDAP servers! This has important implications for LEAD. You can find further details on the MADIS system at http://madis.noaa.gov/.
An even more significant aspect for LEAD is that MADIS data files are compatible with the WRF 3DVAR Data Assimilation System. The MADIS WRF 3DVAR interface supports the ingest of the following observation types: land surface (including ASOS, other METAR, Canadian SAOs, and a large number of mesonets), maritime (including ships, buoys, and C-MAN stations), GPSMET Integrated Precipitable Water, NOAA Profiler Network (NPN) winds, Multi-Agency Profiler (MAP) winds, automated aircraft, radiosonde, and GOES satellite winds (operational or experimental). Read an overview of the MADIS-WRF 3DVAR interface.
