Ceilometers are ground-based, remote-sensing sensors that provide measurements of cloud ceilings and vertical visibility. They use either a laser beam or another light source to detect backscatter of clouds, precipitation, and aerosols. Ceilometers can provide detailed and accurate measurements in all types of weather conditions and have low operating costs. Ceilometers are typically used in boundary layer and cloud research applications.

The microwave radiometers (MWRs) are ground-based radiometers manufactured by Radiometrics Corporation and operated by the Atmospheric Radiation Measurement (ARM) Research Facility. MWR measures brightness temperature at 23.8 and 31.4 GHz to derive column-integrated amounts of water vapor and liquid water in the atmosphere. MWR has a field of view (FOV) from about 5.9 to 4.5 degrees depending on the channel and has a typical time resolution of 20 s for sky-view observations.

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 Total Sky Imager (TSI) is a ground-based, optical instrument that is manufactured by Yankee Environmental Systems (YES), Inc. TSI can provide full-color, hemispheric images of the sky during the day by using a charge-coupled device (CCD) imager. It also can provide measurements of fractional sky cover and sun obscuration by cloud. TSI can be mounted on mobile platforms such as trailers and research vehicles, allowing it to collect cloud cover measurements in various locations during a field investigation.

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%.
