NOAA's
Hurricane Research Aircraft
These aircraft are maintained and operated by
NOAA's Aircraft Operations Center.
Gulfstream IV jet
"Gonzo" N49RF
NOAA's Gulfstream-IV
SP jet is a state-of-the-art, high altitude research
platform. 'Gonzo' was aquired in 1996 to improve NOAA's tropical
cyclone forecast capability by being able to deploy dropsondes from high altitude over large
areas of open sea, where few observations are available. Track
forecast improvements on the order
of 20% are scientifically possible through use of this
dropsonde data. Such reduction in track errors should reduce the
average warning area by at least 10% (34 miles), saving the
public more than $45M in 5 years.

WP-3D Turboprop Aircraft
 "Kermit" N42RF
 "Miss Piggy" N43RF
The WP-3Ds, N42RF and N43RF,
have been the primary airborne platforms for meteorological
research in NOAA since the late 1970s. They provide access to
the lower and middle troposphere with large payload, large
fuselage volume, long duration, and long range. Aircraft
instrumentation includes fight-level
data sensors, airborne
radars with Doppler wind finding,
cloud physics instrumentation (including electric field
measurements), remote sensors
for surface wind and rainfall estimation,
expendables (e.g.; dropsondes, AXBTs, AXCPs, and drifting
buoys), and an aircraft-satellite
data link (ASDL) to transmit data back to the
ground. Some equipment, such as that for remote sensing of
sea-surface conditions or for atmospheric electricity
measurements, is unique to one airframe or the other. In
addition to the hurricane research mission, for which they were
originally procured, these aircraft support diverse programs
throughout NOAA, outside the agency, and internationally.
