abstract = "his work proposes the development and applications of a network of
high speed cameras for observation and study of lightning flashes.
Four high-speed cameras are being acquired to be part of the
RAMMER network. They are capable to record high resolution videos
up to 1632 x 1200 pixels at 1000 frames per second. A robust
system is being assembled to ensure the safe operation of the
cameras in adverse weather conditions and enable the recording of
a large number of lightning flashes per storm, larger than the
values reported to date. As the amount of physical memory to
record only 1 second of data is something like 3 - 4 GBytes, there
is no way to make long recordings of thunderstorms, so a
triggering system was conceived to address this problem and do the
recordings of 2 seconds of data automatically for each lightning
flash. The triggering system is an optical/electromagnetic system
that is being tested since September/2010 and the whole system is
under testing yet. This lightning information from the video
recordings will be correlated with data from the sensors of the
Brazilian Lightning Detection Network (BrasilDAT), from a network
of electric field fast antennas, slow electric field antennas and
Field-Mills, as well as with data from the LMA (Lightning Mapping
Array) to be installed in 2011 in the cities of Sao Paulo and Sao
Jose dos Campos. The following objectives are envisaged: a) make
the first three-dimensional reconstructions of the lightning
channel with high speed cameras and verify its dependence on the
physical conditions associated with each storm; b) to observe
almost all CG lightning flashes of a single storm cloud in order
to compare the physical characteristics of the CG lightning
flashes for different storms and their dependence on physical
conditions associated with each storm; c) evaluate the performance
of the new sensors of BrasilDAT network in different localities
and simultaneously. The schematics of the sensors will be shown
here, with statistics of the first results of of the triggering
system accuracy, pictures and the first lightning recordings of
the observation sites. The main objectives will be also discussed
in more details.",
