DASH Slow Strain Rates from Brady Hot Springs Geothermal Field during PoroTomo Deployment Period


This submission contains slow strain rates summed to radians over 30 second intervals [rad/s] derived from horizontal distributed acoustic sensing measurements (DASH) of Brady geothermal field during PoroTomo deployment (2016-Mar-14 to 2016-Mar-26). There is one file corresponding to each day written in *.mat format for use with Matlab. The format for the binary Matlab .mat files are defined at: https://www.mathworks.com/help/pdf_doc/matlab/matfile_format.pdf.
One such file includes the following variables:
'flist': list of raw DASH files used in the summation
'time_tag_mdt': sample time tag in datetime format with hours given in 24-hr format (yyyy/MM/dd HH:mm:ss.SSSSSSS)
'time_tag_uts': sample time tag in Unix time
'strain_rate_summed_over30s_in_radians_per_second': slow strain rates summed over 30 second intervals in units rad/s
'sample_standard_deviation_in_radians_per_second': corresponding sample standard deviation of slow strain rates in units rad/s

The PoroTomo final technical report, raw DASH data, and software repository are also available through the links below.
