The Airborne Glacier and Land Ice Surface Topography Interferometer (GLISTIN-A) is an airborne, interferometric synthetic aperture radar. GLISTIN-A operates in the Ka-band (35.6 GHz), allowing the instrument to penetrate the top layers of snow and limit atmospheric attenuation. GLISTIN-A provides measurements of glacial and land ice surface topography and elevation at a spatial resolution of around 3 m. GLISTIN-A is ideal for measuring ice sheet elevation and studying glacial topographic changes due to its high spatial resolution and accuracy.

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.

GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Airborne Simulator (GCAS) is an airborne push-broom instrument consisting of two spectrometers. It was developed by the Radiometric Calibration and Flight Development Laboratory at Goddard Space Flight Center (GSFC) as a simulator for the GEO-CAPE mission. The first spectrometer in GCAS operates in the ultraviolet to visible (300-490 nm) range for air quality observations of nitrogen dioxide (NO2), ozone (O3), formaldehyde (HCHO), and other trace gases. The second spectrometer operates in the visible to near-infrared (480-900 nm) to provide measurements of ocean color. GCAS has a typical spatial resolution of 250m across track and 500m along track at an altitude of 9 km and has a frame rate of 12 Hz.

The Cloud Physics Lidar (CPL) is an airborne lidar system designed specifically to provide multi-wavelength measurements of cirrus clouds, sub-visual cirrus clouds, and aerosols. It measures lidar backscatter across three wavelengths: 355 nm, 532 nm, and 1064 nm. These measurements can be used to derive cloud optical depth, particle size distribution, extinction profiles, aerosol layers, and other properties. CPL has a vertical resolution of 30 m and a typical horizontal resolution of 200 m.

The Second Generation High Spectral Resolution Lidar (HSRL-2) is an airborne lidar developed by the NASA Langley Research Center. HSRL-2 measures aerosol backscatter at the 355, 532, and 1064 nm wavelengths and aerosol extinction at the 355 and 532 nm wavelengths. It has a horizontal resolution of 1-2 km and a vertical resolution of 15 m, and it takes measurements roughly every 0.5 seconds. It replaced the High Spectral Resolution Lidar (HSRL).

The Airborne Visible InfraRed Imaging Spectrometer - Next Generation (AVIRIS-NG) is an airborne imaging spectrometer developed by Jet Propulsion Laboratory (JPL) to operate alongside and eventually replace the AVIRIS Classic. AVIRIS-NG has been designed to operate aboard NASA’s ER-2, a Twin Otter, and a B-200. AVIRIS-NG operates between 380 nm - 2510 nm with 5nm spectral resolution. AVIRIS-NG has a spatial resolution of 18 m at 20 km altitude and is often used for terrestrial ecology research investigations.

The High Altitude Lidar Observatory (HALO) is an active remote, airborne lidar developed by NASA Langley Research Center. HALO operates across 4 wavelengths (1645, 1064, 935, 532 nm) and uses a combination of Differential Absorption Lidar (DIAL) and High Spectral Resolution Lidar (HSRL) methods to measure lidar backscatter and depolarization ratio. It provides vertical profiles of aerosol and cloud optical properties, atmospheric water vapor, and methane at a data rate of 2 Hz. HALO has a nominal spatial resolution of 12 km horizontally and 315 m vertically at an altitude of 10 km.
