Overview


MADIS subscribers have access to an integrated, reliable, and easy-to-use database containing real-time and archived observational datasets plus real-time surface analyses grids. To gain access to the MADIS observational database, please fill out a data application form. This will help the MADIS team assess your needs and provide you with the correct data restriction access.

MADIS ingests data files from NOAA data sources and non-NOAA data providers, decodes the data and then encodes all of the observational data into a common format with uniform observation units and time stamps. Quality control checks are conducted and the integrated data sets are stored in the MADIS database with a series of flags indicating the quality of the observation from a variety of perspectives (e.g. temporal consistency and spatial consistency), or more precisely, a series of flags indicating the results of various QC checks. MADIS users and their applications can then inspect the flags and decide whether or not to use the observation.

MADIS data is made available to the enterprise using multiple data transfer protocols via the Internet:
