Development of technologies for low-cost oceanographic unmanned aeronautical vehicles. [PDF]
, 2009 Oceanographic research vessels and buoys typically provide high-resolution, shortrange measurements at a high sample rate. Satellites provide wide-range, low-resolution measurements at a low sample rate. Therefore a gap exists in oceanographic observation capability for medium-range, high-resolution measurements at a high sample rate.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.
