EarthScope infrasound · microbarograph · pascals
Atmospheric waves, folded flat.
Queries the EarthScope infrasound repository through service.iris.edu/fdsnws/dataselect/1/ on BDF or HDF channels, parses raw pascal text columns, then compresses acoustic waves into the matching daily long-period view.
