WP-3D Research Aircraft
The WP-3Ds, N42RF and N43RF (symbols) , 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 (See Aircraft Performance). Aircraft instrumentation includes fight-level data sensors, airborne radars with Doppler wind findin
g, cloud physics instrumentation (including electric field measurements), remote sensors for surface wind and rainfall estimation, expendables (e.g.; dropsondes, AXBTs, and drifting buoys), and an aircraft-satellite data link (ASDL) to transmit data bac
k 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 p
rocured, these aircraft support diverse programs throughout NOAA, outside the agency, and internationally.
