The Portable Remote Imaging Spectrometer (PRISM) is an airborne push-broom spectrometer developed at Jet Propulsion Laboratory (JPL). PRISM was designed to help provide the necessary spectral, spatial, and temporal resolution needed to characterize events across coastal zones that satellite observations could not offer. The spectrometer within PRISM operates in the near ultraviolet to near-infrared range (350-1050 nm) to collect imagery across coastal ocean regions. PRISM also consists of a two-channel radiometer that operates in the short wave infrared (1240 and 1640 nm) wavelengths to provide accurate ocean color measurements. It has a high temporal resolution (167 Hz) and can fly below cloud flight altitudes allowing it to resolve spatial features down to 30 cm.

The Tail Doppler Radar (TDR) is a vertically scanning, pulse Doppler radar installed on the tail of research aircraft. The original instrument, designed by NOAA and NCAR, was tested on NOAA aircraft and has since expanded to multiple platforms. This X-band radar with a magnetron transmitter has a scan rate of either five or ten rotations per minute and a corresponding range gate of 150 or 300 meters.

A dropsondes or dropwindsondes are in situ instruments designed to be released from aircraft. They are equipped with Global Positioning System (GPS) receivers and sensors to collect profile measurements of pressure, temperature, humidity, wind speed, and direction. Dropsondes are important during field investigations because they allow researchers to collect vertical profiles in remote locations and during severe weather events. Dropsondes typically have a vertical resolution of 5 m and provide measurements of wind speed/direction every 0.25 seconds and temperature, pressure, and humidity every 0.5 seconds.

The Airborne Vertical Atmospheric Profiling System (AVAPS) is an airborne system that utilizes dropsondes and Global Positioning System (GPS) receivers to collect in situ profiles of atmospheric state parameters. It provides profile measurements of temperature, pressure, and humidity at a sampling frequency of 0.5 s and measurements of atmospheric winds at a frequency of 0.25 s. AVAPS has a vertical resolution of about 10 m and can allow for dropsonde launches every 20 s. AVAPS was developed by the National Center for Atmospheric Research (NCAR) for the NASA Global Hawk, but it can be deployed on other aircraft such as the DC-8 and P-3.
