Thankfully it's open access. :-)
"Motivated by experiencing extreme turbulence during a mission into Hurricane Ian (2022), this research develops a novel “bumpiness index” to objectively quantify the three-dimensional turbulence felt by scientists, pilots, and crew members on NOAA’s WP-3D (hereafter P-3) Orion Hurricane Hunter aircraft missions. The bumpiness is derived using physics first principles and accounts for translational and rotational accelerations about an aircraft’s three Cartesian axes. Since rotational motions are experienced differently depending on where someone is on a plane, the bumpiness index takes into account seat position. We then rank the bumpiest flights in recent history by gathering flight-level data from every tropical cyclone mission on the P-3 since 2004 when data needed from missions for this analysis became readily available as well as data from the infamous flights into Hurricanes Allen (1980) and Hugo (1989). Based on the maximum bumpiness value, the objective algorithm shows that the flight through Hurricane Hugo was the most turbulent ever with the flight into Hurricane Ian ranked second."
