    Data Access

    This website includes visualizations of WWLLN lightning data, but does not include stroke level data. For stroke level data, please contact Bob Holzworth at bobholz@u.washington.edu.

    Near Real-Time Data

    Note that WWLLN data used for archiving is processed separately from almost real-time WWLLN data. This may cause differences in visualizations as they appear in almost real-time compared with archived versions.
