As of February 2016, the Transportable Array (TA) component of the USArray/EarthScope project has deployed total of 32 stations equipped with meteorological sensors: wind speed (channel = LWS), wind direction (LWD) and outside temperature (LKO). Although these stations are deployed in various regions (the southeast US, Canada, New Mexico), 25 are spaced approximately 90 km apart and therefore could be considered a meteorological subarray (Figure below).
The above stations are also equipped with infrasound sensors (BDF) and, therefore, the data gathered by the meteorological and acoustic channels of these stations provide a suitable data set for analyzing the relation between wind and temperature variations and the changes in barometric pressure noise. To facilitate such an analysis, the new IRIS DMC TA Meteorological Subarray Reference Data Set data product (ds.iris.edu/ds/products/ta-met-subarray/) has been assembled. This data set uses a standard methodology to highlight variations in wind speed, wind direction, temperature and barometric pressure and their potential relation for the deployment days in 2013 and 2014 in both graphical and textual formats.
