The Spectron Engineering-590 (SE-590) Spectroradiometer is an airborne or ground-based portable spectroradiometer manufactured by Spectron Engineering. SE-590 uses a charge-coupled device (CCD) area array detector to measure reflectance. It operates in the visible/near-infrared to short-wave infrared spectral range (350-2500 nm). SE-590 has a ground resolution of 4.5 meters at a flight altitude of 300 meters.

The Modular Multiband Radiometer (MMR) is an airborne multispectral radiometer manufactured by Barnes Engineering Company. MMR measures radiance across 8 spectral bands in the infrared and visible wavelengths (0.4-12.5 μm) to provide imagery of vegetation and other surface features. At an altitude of 300 m, the MMR has an instantaneous field of view (IFOV) of approximately 79 m and a 15-degree field of view (FOV). It is typically deployed on small aircraft such as helicopters but can be deployed on ground-based platforms as well.

The POLarization and Directionality of the Earth’s Reflectances (POLDER) is a spaceborne passive radiometer that was onboard the Japan Aerospace Exploration Agency’s Advanced Earth Observing Satellite. POLDER has also been utilized in several airborne investigations to perform instrument calibration and to provide measurements of surface reflectance and solar radiation. POLDER has a ground spatial resolution of 7 km x 6 km at nadir and operates across eight discrete spectral bands (443 nm - 910 nm).

The Airborne Tracking Sun Photometer (ATSP) is an airborne instrument that measures direct solar beam transmission. The ATSP measures solar beam transmission through multiple channels with wavelengths ranging between 354 and 2139 nm. These measurements can be used to derive aerosol optical depth and other aerosol properties. There are multiple versions of this instrument, including one developed by the NASA Ames Research Center.

C-band scatterometers are airborne remote active non-imaging sensors that measure microwave backscatter. C-band scatterometers are typically used to measure ocean surface winds but can be used for ice, vegetation, and soil surface properties measurements. They operate in the C-band frequency range (4-8 GHz) and have the capability to provide measurements during the day and night.
