2.6. MADIS Data
Meteorological Assimilation Data Ingest System (MADIS) consists of NOAA and non-NOAA data providers and provides observational data in a common format, with quality checks. This information is focused on METAR data.
Note: METAR data is also available via other sources (e.g., NCEP prepbufr files); METAR data from MADIS allows for verification over CONUS and OCONUS.
- Recommended use
METAR data are commonly used for near-surface verification of standard meteorological variables, such as temperatures, dew point temperature, wind speed, visibility, and precipitation, and precipitation type.
- File format
- Location of data
Data can be accessed via ftp, OPeNDAP, Text/XML Viewer, or LDM
- Access restrictions
In order to access the data, a data application must be filled out: https://madis.ncep.noaa.gov/data_application.shtml
Some of the datasets are restricted. For more details see: https://madis.ncep.noaa.gov/madis_restrictions.shtml
