Global Lighting Dataset GLD360

Global Lighting Dataset GLD360 tracking lightning and severe weather
    Overview

     Overview

      Vaisala Global Lightning Dataset GLD360 is a service that provides real-time lightning data for accurate and early detection and tracking of severe weather. The data provided is generated by a Vaisala owned and operated world wide network.

      • Detect lightning as it happens, anywhere:
        First truly global and accurate, real-time lightning coverage.  No data gaps - unlike satellites or radars.
      • Sold as a service:
        No capital expenditure, no equipment, no maintenance.
      • Deliverable in a week:
        Begin receiving data in a week and quickly provide better end-user service.
      • Best accuracy:
        Outperforms all other long-range lightning detection systems. Minimal day/night effect.

      Lightning Data Information

      The GLD360™ dataset product includes delivery of global lightning data. The lightning data includes cloud-to-ground stroke information, cloud-to-ground flash information and survey level cloud lightning information.

      The lightning data file includes the following information (as a minimum):

      • Date and Time (UTC with milliseconds accuracy)
      • Latitude and Longitude (location)
      • Peak amplitude (kA)
      • Polarity (+/-)

      Lightning Data Format

      The GLD360™ data can be provided in various formats, including but not limited to the following:

      • ASCII
      • Binary (proprietary Type 97)
      • XML
      • Others as requested such as KML, BUFR, GRIB

      Lightning Data Delivery

      The GLD360™ data can be delivered in real-time (less than 60 seconds latency), near real-time (>2 minute bins) or in archive format (>24 hours). The delivery mechanism is via satellite in North America, secure shell Ethernet/internet (TCP/IP) or FTP.

      The GLD360™ Network Specifications

      • Current flash detection efficiency greater than 70% in most areas of the Northern hemisphere and between 10-50% in the rest of the Southern hemispheres. This is the best available for any worldwide VLF/LF long range network.
      • Median location accuracy of 5 km or better
      • Network uptimes nearing 99%
      • Data feed uptimes of better than 99%
      • Event timing precision of 1 microsecond RMS
      • Peak amplitude measurements
      • Polarity
