The Advanced Solid-state Array Spectroradiometer (ASAS) is an airborne, passive multi-angle spectrometer operated by NASA Goddard Space Flight Center (GSFC). ASAS measures reflectance across 30 spectral channels in the 450 to 880 nm wavelength range to help characterize the directional variability of various land surface cover types. At typical flight altitudes of 4,500 to 5,000 m, ASAS has a spatial resolution of 3 to 4 m at nadir. It has a frame rate ranging from 3 to 64 frames per second.

This is a Daedalus AADS-1268 scanner that flies on the ER-2 aircraft and simulates the LANDSAT Thematic Mapper instrument, with slightly higher spatial resolution. The TMS is used for collecting data similar in application to data collected by the Thematic Mapper (TM) sensor including Earth resources mapping, vegetation/landcover mapping, and geologic studies.

The Thermal Infrared Multispectral Scanner (TIMS) is an experimental aircraft scanner providing six-channel spectral capability in the thermal infrared region of the electromagnetic spectrum. The instrument was designed and built by Daedalus Enterprises, Inc. of Ann Arbor, Michigan, and is operated from a Lear Jet by NASA's National Space Technology Laboratories' (NSTL) Earth Resources Laboratory (ERL).

The Airborne Synthetic Aperture Radar (AIRSAR) was an airborne P-, L-, and C-band radar system developed by the Jet Propulsion Laboratory (JPL). It was able to penetrate through clouds and operate at night to provide measurements of radar backscatter. It also could penetrate forest canopy, dry snow cover, and sand in two of its imaging modes. AIRSAR operated across three frequencies: 0.45 GHz, 1.26 GHz, and 5.31 GHz. It had a horizontal resolution of 10 m and a swath width of around 10-15 km at a flight altitude of 8,000 m. AIRSAR is now retired and flew its last mission in 2004.

The Compact Airborne Spectrographic Imager (CASI) is a relatively small, lightweight hyper-spectral sensor that has been used on a variety of light aircraft. CASI was developed by Itres Research Ltd (Alberta, Canada) in 1988 and was designed for a variety of remote sensing applications in forestry, agriculture, land-use planning, and aquatic monitoring. By allowing user-defined configurations, the 12-bit, push-broom-type sensor (333 scan lines per second) using a charge-coupled detector (CCD) can be adapted to maximize either spatial (37.8° across track field of view, 0.077° along-track, 512 pixels – pixel size varies with altitude) or spectral resolution (288 bands at 1.9 nm intervals between 400 and 1000 nm).

The Spectron Engineering SE-590 is a portable battery or A/C operated spectroradiometer consisting of a CE500 data analyzer/logger controller, CE390 spectral detector head and an external battery charger/power supply. The CE500 is a self contained microprocessor based controller which processes the signal from the detector head, amplifying and digitizing it with 12 bit resolution. For each spectral scan, the controller actuates the CE390 shutter, measures and stores the dark current, calculates optimum integration time, acquires the spectrum and automatically subtracts the noise for all 256 spectral elements. A series of scans can be taken and automatically averaged. The spectrum is stored in a double precision register which saves the entire 12-bit binary spectra until it is transmitted through the RS-232C port. The spectral detector head uses a diffraction grating as the dispersing element; the spectrum is imaged onto a 256 element photodiode array. Each element integrates simultaneously acquiring the spectrum in a fraction of a second. The interconnect cable from the spectral head to the controller couples the spectral signals to the controller, and the timing and control signals to the detector head. A shutter in the detector head, operated by the controller, closes the light path for dark current measurements.

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.

If instrument model or detailed specification information is not available, can use this instrument entry for radiometers of various types (typically microwave-band) that are flown on aircraft.

The Airborne Visible/Infrared Imaging Spectrometer - Classic (AVIRIS-C) is a passive imaging spectrometer developed at the Jet Propulsion Laboratory (JPL) for Earth remote sensing. AVIRIC-C was designed to operate aboard NASA’s Earth Resources 2 (ER-2) aircraft. It has a spatial resolution of 20 meters and takes 12 scans per second. AVIRIS-C operated in the spectral region of 0.41 µm to 2.45 µm, making it particularly useful for a wide variety of Earth Science applications. It has been replaced by the Next Generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG), though AVIRIS-C remains in operation.

Rain gauges are ground-based instruments that provide in situ measurements of liquid precipitation amounts over a set time. There are multiple types of rain gauges that each collect and record data differently such as the tipping bucket rain gauge and weighing precipitation gauge. Rain gauges can be deployed in various locations due to their relatively small size and easy set-up and are typically colocated with other precipitation instruments such as disdrometers to provide more details about precipitation being collected such as precipitation rate and size distribution.
