Disclaimer Regarding Data Usage

No warranties are expressed or implied regarding the accuracy, completeness, or reliability of the information provided. Data users are cautioned to consider the provisional nature of the data before using it for decision making. Mesonet data, in particular, should be considered experimental and not always reliable or accurate. NOAA does not own or operate mesonet sites and is not responsible for site maintenance or data accuracy. The user assumes the entire risk related to use of the data. NOAA and its data providers disclaim liability of any kind whatsoever, including, without limitation, liability for quality, performance, merchantability and fitness for a particular purpose arising out of the use, or inability to use the data.

MADIS runs operationally in real-time in National Weather Service facilities. MADIS also runs quasi-operationally in a research test environment at the NOAA Earth System Research Laboratory (ESRL) Global Systems Division (GSD), where new advances are developed and tested prior to being put into operations. The ESRL/GSD system also has an archive of saved real-time data, and serves as the backup to the operational system. Note that the ESRL/GSD system is not an operational data facility.

MADIS data providers request that users not redistribute the data or display it on web pages without notifying NOAA. To notify NOAA, contact the MADIS team at madis-support@noaa.gov. Redistribution of data in distribution categories other than "full distribution" is not allowed.

It would also be very helpful to the MADIS data providers, particularly the providers of aircraft and mesonet data, if publications and web pages that depend upon substantial use of their data acknowledge their contribution by including a statement similar to: This study was made possible in part due to the data made available to the National Oceanic and Atmospheric Administration by ---- (fill in the provider name or names, e.g. "the Kansas Department of Transportation", "MesoWest", or "the following commercial airlines: American, Delta, Federal Express, Northwest, United, and United Parcel Service").
