Magnetometers
The fluxgate magnetometers measure 3 components of the Earth's magnetic field in the geographic frame of reference, namely X
(geographic north), Y (geographic east) and Z (vertically downward). The data is sampled at 8 Hz and the instrument's bandwidth
is 0-2 Hz with an amplitude resolution of 0.025 nT. The CANOPUS data was downsampled to 5 second resolution due to bandwidth limitations.
We are now able to transfer the full 8 Hz resolution data. This is downsampled to 1 Hz to form the primary data product available from
the CSSDP. However, the 8 Hz data is freely available for those interested in higher frequency ULF phenomena - please contact the PI for details.
There are plans to install another 15 fluxgate magnetometers and 8 sets of induction coils as part of the CARISMA array expansion funded by CFI.
The data will be made available through the CSSDP as the instruments are deployed.
