Integrated Mesonet Data
Overview
Description
The integrated mesonet is a unique collection of thousands of mesonet stations from local, state, and federal agencies, and private firms that help provide a finer density, higher frequency observational database for use by the greater meteorological community. The Integrated Mesonet portion of MADIS started with MADIS' launch on July 1, 2001 with the following 7 providers:
By the end of the year four additional providers were added:
- Citizens Weather Observer Program (CWOP)
- Florida Automated Weather Network (FAWN) FL-MESO
- GPS-Met
- Kansas Department Of Transportation (KSDOT)
- University of Utah Department of Atmospheric Sciences MESOWEST
- Interagency Remote Automatic Weather Stations (RAWS)
- Denver's Urban Drainage and Flood Control District (UDFCD)
MADIS Meteorological Surface Data Providers continue to grow every year.
- Goodland, KS NWS Forecast Office (GLDNWS)
- Iowa Department of Transportation (IADOT)
- Denver/Boulder NWS Forecast Office (INTERNET), consisting of the following networks:
- National Center for Atmospheric Research (NCAR)
- National Renewable Energy Laboratory's (NREL) National Wind Technology Center
- Colorado State University
- University of Colorado Niwot Ridge Long-Term Ecological Research Program
- Minnesota Department of Transportation (MNDOT)
The Hydrometeorological Automated Data System (HADS)/Automated Flood Warning System (AFWS) were integrated into operational MADIS and went live at the end of 2016. MesoWest was providing some HADS data before this integration. HADS/AFWS is broken up into three different areas of MADIS: Atmospheric, Hydrological and Snow. The atmospheric data is a part of the Integrated Mesonet and includes temperature, winds (direction, speed and gust), pressure, dewpoint, relative humidity, and accumulated precip. The hydrological data is a part of the Hydrological Surface dataset and includes river stage and flow. Lastly the snow data is a part of the Snow dataset and includes snow depth and snow water equivalent. The HADS sites can change per owner operational needs.
Geographic Coverage
Global

Data Schedule
Data schedule is set by provider and ranges from every 5 minutes to once per day. The current and previous hour's data are processed every 5 minutes. Data are stored based on their observational time stamp in netcdf files that contain observations from the top of the hour until 59 minutes into the hour (e.g., the 0000 file covers 0000 - 0059).
Data that arrive after 2 hours following the time of the observation are processed in a "data recovery" mode, where once a day batch processing is performed to reprocess data that are 35 day's, 7 day's old, and 1 day old. These data are available with all communications methods supported by MADIS except for ldm.
