MADIS ingests data from <a href="madis_datasets.shtml">NOAA data sources and non-NOAA providers</a>, decodes the data then encodes all of the observational data into a common format with uniform observational units and time stamps. <a href="madis_qc.shtml">Quality checks</a> are conducted and the integrated data sets are stored along with a series of flags indicating the results of the various QC checks. MADIS provides several methods for <a href="https://madis-data.ncep.noaa.gov/index.shtml">users to access</a> the data to meet their needs. Users can request data from July of 2001, which is when MADIS was first available to the public, to the present. </p> <p> To provide these services, MADIS leverages partnerships with international agencies; federal, state, and local agencies (e.g., states' Departments of Transportation); universities; volunteer networks; and the private sector (e.g., airlines, railroads) to integrate and quality check observations from their stations with those of NOAA. <p> MADIS runs operationally at the NWS National Centers for Environmental Prediction (<a href="https://www.ncep.noaa.gov">NCEP</a>) Central Operations (<a href="https://www.nco.ncep.noaa.gov">NCO</a>) as part of the Integrated Dissemination Project (IDP).
