The mission planner also receives updated, near-real-time wind speeds while in the air using hand-launched dropsondes (hand-sized, parachute-equipped wind indicators).
Sophisticated new software integrates real-time wind data from numerous sources--GPS dropsondes, radar, and light distance and ranging--via an encrypted datalink, then calculates computed aerial release points, as well as probable landing areas for unguided or failed chutes.
The environmental Global Hawk also includes a system to deploy dropsondes -- small tube-shaped devices, equipped with parachutes that gather and transmit data as they gently fall to the ocean surface -- that will observe vertical profiles of temperature, wind, barometric pressure and humidity through the outflow layer and the environmental structures below.
