Gravity gradient seismic noise characterization was conducted at the LIGO Livingston Observatory in Louisiana. Researchers from SCIOPS performed measurements using Guralp sensors, focusing on frequencies between 1-30 Hz. The dataset was last updated in June 2001.
Use Cases
- Analyze seismic noise amplitude across the 1-30 Hz frequency band.
- Compare relative microseismic noise levels between sensor pairs separated by 4 km distances.
- Characterize gravity gradient noise variations with sensor separations of 5-30 meters.
- Model environmental noise contamination for interferometer data cleaning algorithms.
Strengths
- Data collection involved dedicated 2-3 weeks for preliminary gravity gradient measurements.
- Measurements were taken at a major NSF-sponsored observatory, LIGO Livingston.
Limitations
- The dataset is from 2001 and may not reflect current noise conditions.
- Specific row counts, column details, and file formats are unknown.
- Measurements were primarily conducted inside buildings, limiting outdoor environmental characterization.
