Utah Testing and Training Range 2010: Large scale infrasound sensor deployment to Utah and Idaho.

A large scale infrasound deployment was undertaken during the summer of 2010 using large blasts (19.5‐tons TNT, 8.8‐tons TNT, and 1.9‐tons TNT) that were taking place at the Utah Testing and Training Range west of Salt Lake City, UT. A total of four sensors were deployed in the near field and additional 114 infrasound sensors were placed in the “far field.” Six arrays of five elements each were delayed along a “stratospheric arc” 220‐km from the source from a bearing of 300° to 355° in 5* increments. Additional six arrays (3 with three elements and 3 with six elements) were deployed in a northern “thermospheric” line, designed to separate the thermospheric line from the stratospheric one. Data will be reported on measurements from 24‐explosions. The implications of these measurements on empirical models of atmospheric structure (e.g., G2S) will be discussed.
