Using the new LOFAR2.0 upgrade for lightning imaging

LOFAR has been used to image lightning initiation, leader stepping, dart leaders, needles, and more
with sub-meter resolution and high sensitivity. Over the last few years LOFAR has been almost
completely rebuilt from the ground-up into LOFAR2.0. Apart from the physical antennas, nearly all of
the analog and digital processing chains have been completely replaced and upgraded. In addition to
greater bit-depth and better amplifiers, a new automatic white-rabbit based time calibration will allow
for easier and faster data processing. Combined with a faster network that allows for less down-time,
more lightning flashes per thunderstorm can be observed and mapped with high precision. LOFAR2.0
will also have triple the number of processing pipelines, thus allowing for observing simultaneously
with both the low-band antennas (10-90 MHz) and the high-band antennas (110-240 MHz). The higher
frequencies will allow for significantly higher resolution, perhaps even allowing for the resolving of the
sub-meter widths of streamer bursts during lightning initiation. This poster will discuss some of the
new and still-planned upgrades to LOFAR system, as well as our various imaging techniques such as
our impulsive imager and near-field beamforming (TRI-D and ATRI-D).
