We are looking for a way to be able to identify signals as unusual. Are there any catalogs of known signals we could use as a basis? We are aware of CTBTO’s IRED catalog but we have not been able to access it.

Hello safrick, and welcome back to the community!
I know of the EarthScope IS databases, which may be of help:
- NSF SAGE: Data Services Products: Infrasound
- NSF SAGE: Data Services Products: Infrasound-AELUMA
- USArray Infrasound Data Products at IRIS | Earthscope
Also these papers could provide contacts about IS datasets:
- Introduction to a community dataset from an infrasound array experiment at Mt. Etna, Italy | Scientific Data
- https://www.mdpi.com/2072-4292/15/5/1455
- "Dataset for 'A Deep Learning Approach for Infrasound Signal Detection " by Evi Ofekeze, Jeffrey B. Johnson et al.
- ESSD - International Monitoring System infrasound data products for atmospheric studies and civilian applications
- https://www.aanda.org/articles/aa/full_html/2021/10/aa41106-21/aa41106-21.html
And, related to the last one, there is also the CNEOS Fireballs database that, in some cases, has infrasound data available: https://cneos.jpl.nasa.gov/fireballs.
I hope some of the above can be of help. And, if anyone else in the community has more links/further data, let us know!
