+    description: "Distributed Acoustic Sensing (DAS) provides a new, non-invasive mean for high resolution subsurface imaging in urban, developed environments by repurposing existing telecommunication cables. This DAS dataset is collected over 3 months between December 2021 and April 2022 at a fibre optic network dedicated to research, i.e., ALIRT (Australian Lightwave Infrastructure Research Testbed) in Melbourne, Australia. In this deployment, a 25 km long fibre optic cable is transformed into 6252 channels at 4 m spacing, starting from Melbourne Central Business District running west to east. Silixa iDAS interrogator is used, which measures strain-rate at 1 kHz with a fixed gauge length of 10 m. The time series recorded is decimated to 62.5 Hz. This dataset represents the ALIRT-001 Level 1 Decimated Data outputs."
