Sea Surface temperature was used as the abiotic parameter and we obtained an 8-day averaged SST product mapped at 4 km equal angle grids from the Pathfinder project data archive in the Physical Oceanography Distributed Active Archive Center (PODAAC, http://podaac.jpl.nasa.gov).nasa.gov
Source locations were randomly determined from grids whose distance to the station was between 7.95 and 8.05 km and angled from vertically downward at the station of less than 30°, resulting in a depth range of sources of 6.87 8.05 km.
The data grids consisted of 8-day and monthly averaged SSTs on a 4-km equal angle grid.
The distance (km) and the angle (degrees) in the legend are the altitude and the inclination of satellite orbits.
We constrained the fault plane location (latitude and longitude, to be within 0.5° of the initial value), depth (within 10 km) and dip angle (within 5°) for the recursive procedure, and we also slightly changed the initial value by a trial and error process.
In the WEGC OPSv5.6 background information is included at high altitudes (down to 30 km) at bending angle level.

Accordingly, a Computational Fluid Dynamics simulation has been carried out at Mach number (M∞=7), H=35 km altitude with zero Angle of Attack.
