TA-Met-Subarray Reference data set for the TA Meteorological Subarray

UNRELEASED PRODUCT — IN DEVELOPMENT

Status: In development
Last update: 2016-02-22

This data set will be a compilation of the wind (speed and direction) and temperature profiles as well as infrasound sensor’s ambient noise estimates of a selected subarray of the USArray Transportable Array (TA) stations. This subarray includes TA station that were equipped with meteorological sensors during their deployment.

Infrasound-AELUMA Automated Event Location Using a Mesh of Arrays

The AELUMA (Automated Event Location Using a Mesh of Arrays, de Groot-Hedlin and Hedlin, 2015) detection and location algorithm is used to expand IRIS DMC’s infrasound event repository. The USArray TA station’s infrasound data for 2011-2015 are processed and over 2500 automated infrasound source locations were obtained. These events and those of the TA Infrasound Reference Event Database (TAIRED) were merged to form the IRIS DMC’s infrasound event database.

HVSR Horizontal:Vertical Spectral Ratio (HVSR)

UNRELEASED PRODUCTINACTIVE

Status: Inactive
Last update: 2015-09-10

The horizontal to vertical spectral ratio (HVSR) of a station’s ambient noise provides useful information on its site response characteristics. The proposed product allows HVSR computations using available power spectral density (PSD) data and creates a site response database for the TA stations in Alaska.
