The Low Frequency Atmospheric Weather Electromagnetic
System for Observation, Modeling, and Education, or LF AWESOME is a
high-sensitivity radio receiver for the frequency band 0.5-470 kHz.
The receiver is an upgraded version of the VLF AWESOME, which
provided high sensitivity broadband radio
measurements of natural lightning emissions, transmitting beacons,
and radio emissions from the near-Earth space environment. The
expanded capabilities of LF AWESOME allow detection of radio
atmospherics from lightning strokes at
global distances and multiple traverses a round the world. It also
allows monitoring of transmitting beacons in the LF/MF band at
thousands of km distance.
Most of the data is collected on two air-core loop
antennas, oriented orthogonal, to collect the two horizontal
components of the magnetic field. The north-south, or N/S antenna
is sensitive mostly to waves arriving from the north of from the
south direction, meaning it picks up the magnetic field component
in the east-west direction. The other antenna is the east-west
antenna, which is the opposite.
Broadband data contain direct samples of the receiver output, usually
at 100 kHz or 1 MHz sampling frequency. These files essentially
contain everything that the receiver records, entirely
uncompressed. The files are very large, for instance just one
minute of VLF data will produce a ~12 MB file for each antenna
channel. This adds up to 35 GB per day if you have two antenna
channels.
