The Land, Vegetation, and Ice Sensor (LVIS) is an airborne imaging lidar developed and operated by Goddard Space Flight Center (GSFC). It is used for making topographical maps and studying the vertical structure of vegetation and ice. It has an operating wavelength of 1064 nm and has pulse repetition rates up to 500 Hz. LVIS has a swath width of 2 km and a horizontal resolution of 20 m at a flight altitude of 10 km.

Broadband Radiometers (BBR) are modified versions of the Kipp & Zonen CM-22 pyranometers and CG-4 pyrgeometers. They have been modified to be more suitable for airborne platforms through different instrument housing and signal amplification. BBR measures solar irradiance in the 0.2-3.6 μm wavelength range and infrared (IR) irradiance in the 4.5-42 μm range. These measurements can be used to derive net irradiance, radiative forcing, absorption, and albedo. It has a typical sampling rate of 1 Hz and a hemispheric field-of-view.

The Langley Aerosol Research Group Experiment (LARGE) is an in situ airborne instrument suite that measures aerosol and cloud microphysical and optical properties such as size distribution, number concentration, and scattering and absorption coefficient. LARGE consists of multiple instruments including the Ultra-High Sensitivity Aerosol Spectrometer (UHSAS), Particle-Into-Liquid Sampler (PILS), Particle Soot Absorption Photometer (PSAP), Cloud and Aerosol Spectrometer (CAS), Cloud Imaging Probe (CIP), and additional cloud and aerosol sensors. The LARGE instruments operate across the 450-700 nm wavelength range, can detect particles in the size range between 0.003-20μm, and have a measurement frequency of 1 Hz. It is typically used for airborne measurements, but it also can be deployed on ground-based platforms such as vehicles.

A pyrometer is an instrument that measures temperature remotely, i.e. by measuring radiation from the object, without having to be in contact. The KT11 Infrared Radiation Pyrometer provides temperature measurements in the range of -30 to 500 Celsius by intercepting incoming infrared radiation emitted by surfaces. The high stability and noise suppression of the instrument allows for high response times of readings as well as the capability of temperature measurements of small objects. The KT-19II infrared pyrometer was manufactured by Heitronics, and sees a spectrum of 8-12um. The KT-19 is a radiometer that measures the brightness temperature of the surface beneath the aircraft. The KT-19 instrument can estimate the surface temperature by knowing the emissivity of the target. The response time is adjustable from 5 msec, to monitor and control extremely short production cycles, up to 10 minutes, to integrate measurements in long-term thermal processes with an extremely high resolution.

The Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4-STAR) is an airborne sun-sky spectrometer that measures direct solar irradiance and sky radiance. These measurements can be used to retrieve column-integrated information on aerosols, clouds, and trace gases such as aerosol optical depth, extinction, and single scattering albedo. 4-STAR operates in the 350-1650 nm wavelength range and has a typical horizontal resolution of about 100 m.

The Solar Spectral Flux Radiometer (SSFR) is an airborne radiometer developed by the Ames Atmospheric Radiation Group. It provides remotely sensed measurements of solar spectral irradiance in the troposphere. SSFR operates across the 300-2150 nm wavelength range and has a spectral resolution of 8-12 nm. It has a typical data collection rate of 1 Hz and has a radiometric accuracy of 3%.
