With a superior latitudinal coverage, McMaC is capable of monitoring the
plasma density in the entire dayside magnetosphere by employing the normal-mode
magnetoseismic method. The density measurements are taken at 21 L-values
ranging from L = 1.3 to 10.7, corresponding to the midpoints of neighboring
stations. The below figure shows these L-values as well as the expected
scheme to construct the density distribution in the dayside magnetosphere.
McMaC can probe the magnetospheric density distribution by using magnetoseismic methods.
McMaC will also provide an important database of impulsive wave events
to help develop the recently conceived travel-time method. The arrival
time of impulses observed by McMaC will be compared with Tamao’s
MHD model and with computer simulation. Different inversion techniques
will also be explored for inferring the magnetospheric density distribution
from the measurements of travel time.
