An optimal infrasound array at Apatity (Russian Federation)
Introduction
Project no. 1341 from the International Science and Technology Center (ISTC) involves
the installation of an infrasound array at the seismic array of Apatity. With the
existing configuration of the seismic stations, a large number of possible infrasound
arrays can be configured (taken co-location with the seismic instruments as boundary condition).
Here, the responses for all possible layouts (3, 4 and 5 elements) are calculated and evaluated.
On the basis of this, the authors advise to configure the infrasound array
of Apatity with all 8 elements available. This array has the most optimum
resolution and sensitivity of all evaluated responses, necessary to fulfill the goal of
the project being research on infrasound background characteristics. Furthermore, it is
recommended from a financial point of view to partly use differential microbarometers
(p.e. K-304AM sensors or KNMI Microbarometers).
