WWLLN
World Wide Lightning
Location Network
Asking your opinion and comments
The
WWLLN is a collaboration between scientists and engineers, and is directed by the University of Washington.
We are a research network involving a collaboration between universities and institutions around
the globe for collecting VLF radio sferic data for
use in determining the time and location of lightning anywhere in the world.
We are asking those
occasional or regular users of our web pages for your feedback about your use
of these data and about your suggestions and wishes for improvements to our web
pages. Please take a moment and email me your comments in this regard,
to help future network development.
Thanks, Robert Holzworth, Director of WWLLN
For
your information, here are some facts about the system: Presently 33 WWLLN lightning sferic
receiving stations around the world (see the circles with the red * on the WWLLN World
map ) Lightning Location Accuracy: 10 to 15 km (about the
wavelength of the radio waves we detect, and on the spatial dimension of most
thunderstorms) Lightning Time accuracy: < 30 microseconds Antennas: short electric dipoles, allowing operation even
in noisy environments Both in-cloud and cloud-to-ground lightning are located Detection threshold: We detect 10 to 20% of all lightning
with peak current greater than approximately 45 kiloAmps. (based on studies
with regional networks in WWLLN operates on data sales and is not funded by any
governmental grants. WWLLN data are available for purchase for both archival
data back to 2004, as well as near-realtime internet-delivered
data with a cadence of 10 minutes. For those needing faster data feeds, please contact Prof. Holzworth who
can put you in contact with our commercial reseller. New WWLLN hosts are welcome and should also contact
me. In exchange for hosting WWLLN
stations, hosts receive all the global lightning data. Director
