Radar
Radar reflectivity C-band PPI lower-fuselage (LF), 360 degree scan (horizontal) fan beam [Note]
Radar reflectivity X-band RHI tail (TA), 360 degree scan (vertical) [Note]
Radial velocity Doppler X-band RHI tail (TA), 360 degree (vertical) [Note]
Scatterometry
Surface wind speed and rain rate Step Frequency Microwave Radiometer (SFMR). AOML/HRD C-band Scatterometers
Navigational
Position, ground speed INE, LORAN and GPS (Military Precision)
Radar and pressure altitude Radar and pressure altimeters
Cloud and Sky Imagery (daylight)
Side and Nose photography Video Cameras
Note: LF radar data normally recorded every other scan unless a different rate is requested. TA radar and Doppler radar recorded every scan.
