SuomiNet Status Report: May 2003

Prepared by Jeff Weber

    SuomiNet Deployment

    Updated Timeline:


    • Number of sites: 86 SuomiNet sites and ~40 FAA/DOD
    • Fully deployed, no longer accepting applications for sites
    • Global coverage being pursued via aquiring data from other GPS/Seismic sites
      Northern Hemisphere coverage will come first with the aid of Japan's and California's seismic networks
    • Active sites = 86 and their info

    Data Volume

    • Raw data volume approximates .6Mb per Day/Site
    • Raw data designed to be in BINEX Format.
    • Precipitable Water Vapor (PWV) Products: 1-2 Kb per Day/Site in netCDF.
    • Total Electron Content (TEC) Product: 3-5 Mb per Day (not site specific) in netCDF
    • netCDF format is now in use for the value added products of TEC and PWV/IPW
    • Slant measurements: 50-100 Kb per Day/Site

    Data Processing:

    • A FORTRAN data reader was developed at Unidata to read the data from the netCDF files.
    • A netCDF to GEMPAK decoder for visualization of data via GEMPAK/GARP has been completed

    LDM Applications:

    • LDM/IDD Software is being applied to gather the raw data from each site
    • LDM/IDD Software also applied to distribute post-processing PWV/TEC products to the community

    Water Vapor Products Currently Available

    • SuomiNet main page that contains the UNIDATA LDM/IDD GEMPAK 14 hour loops of PWV with an 8km IR Super-National overlay, and archived historical products from these loops.
      There are two loops, one that filters out sites (no overlap) for ease of viewing, and another that includes ALL sites and can be zoomed in for ease of viewing. Both these products are combining SuomiNet sensors with sensors of other agencies, giving a total of 125 reporting locations.
    • --http://www.gst.ucar.edu/gpsrg/realtime/mountainnorth.html Colorado-Wyoming Beta-test
    • --http://www.gst.ucar.edu/gpsrg/realtime (NOAA, USGC, and DOT) and description of process and comparison of US products of Total Electron Content and Integrated Precipitable Water(IPW) compared with GOES imagery. This site also contains archived loops of the IHOP field campaign, ionospheric TEC, MPEG animations, and other products.
    • A map of ALL active SuomiNet sites is available for point and click access to the data products derived from that site.
