1.0 General Description

This data set contains global lightning location data from the World Wide Lightning Location
Network (WWLLN) for the DYNAMO time period.  The data are in a comma-delimited ASCII format.
These data were provided by Dr. Robert Holzworth at the University of Washington.

These data are in a comma-delimited format:

UTC date
UTC time
latitude of stroke

residual error
number of WWLLN stations that saw the stroke

Each file contains 10 minutes of stroke data starting at the time in the file name.


3.0 File Naming Convention


The data files are named as follows:

data.WWLLN.yyyymmddhhnn.10min_Lightning_Data.txt

where
yyyy is the year
mm is the month
dd is the day of month
hh is the UTC hour
nn is the UTC minute


4.0 Data Usage Policy and Requested Acknowledgement


These data are only for DYNAMO investigators.  Do not provide these data to a third party.

WWLLN asks that you only publish analysed WWLLN data, you should not publish lists of strokes in a
place or region (i.e. maps, statistics, etc are fine, but now reproductions of the data set itself).

Note to Authors: Please include this statement in your papers using WWLLN data:

"Acknowledgement: The authors wish to thank the World Wide Lightning Location Network (http://wwlln.net), 
a collaboration among over 50 universities and institutions, for providing the lightning location data 
used in this paper."
