| This is a standardized Distributed Acoustic Sensing (DAS) data file. Original raw data and metadata were obtained, standardized, and converted to HDF5 file format via an automated DAS Data Pipeline developed at the National Renewable Energy Laboratory (NREL). NREL makes no guarantees about the completeness of this data and metadata, so it is recommended to check with the original author for accuracy. More information about this DAS data's origin and nature, as well as the author's contact information, can be found at https://gdr.openei.org/submissions/980.
