ObsPy-Scan ObsPy-Scan is an example of how the ability of ObsPy to handle different data formats can be exploited in little helper applications that are useful in daily work at data centers and observatories. The process of figuring out precise infrasound arrival times is quite a tricky process, the travel times depend on winds, humidity, and many other atmospheric variables that are hard to constrain over such a long travel path. The following was tested on Linux Redhat 6. 7-1) Python Implementation. 2011, Krischer et al. ObsPy provides unified access to read seismograms formatted as GSE2, MiniSEED, SAC, or SEISAN.
