EarthScope USArray Transportable Array (TA) Surface Pressure Observations Sampled at 1 Hz Frequency
Listed in National Center for Atmospheric Research
The EarthScope USArray Transportable Array (TA) contains over 400 seismic station platforms deployed in a pseudo-grid fashion (spaced approximately 70 km apart) across a portion of the United States.
Description
This array is part of a large initiative within the geoscience field to improve earth mapping and understanding of subsurface properties. Individual platforms report for 1 to 2 years and then are retrieved and redeployed farther east.
Atmospheric pressure sensors were added to many platforms in 2010 while the array was deployed in the Central U.S. to assist with identification of seismic signals produced by atmospheric phenomena. These sensors have resulted in a tremendous dataset of surface pressure observations with high temporal frequency not commonly found in atmospheric sciences outside of smaller field campaigns. This dataset provides surface pressure observations at 1 Hz frequency from these deployments beginning 1 January 2010.

The years 2010-2011 feature deployments over the central U.S. Great Plains, 2012-2013 over the interior eastern U.S., and 2014-2015 along the U.S. east coast. While average station life is 1 to 2 years, some deployments have been kept in place and thus have longer records. Further, the next phase of the TA project has begun with several platforms deployed in Alaska, which will continue over the next few years.
There are also deployments located near the Cascade Mountain range in the Pacific Northwest. Data files are provided in HDF5 format, where a single file contains data for a particular year and station. Basic metadata and quality control files are also available.
