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 Pandora Spectrometer System is a ground-based UV-VIS spectrometer used to measure column amounts of trace gases in the atmosphere. It uses total optical absorption spectroscopy for retrievals of ozone, nitrogen dioxide, formaldehyde, and other trace gases. Pandora operates in the 280-525 nm spectral region at a resolution of 0.6 nm. It can make both direct sun and all-sky radiance measurements and has an overall measurement time of 80 seconds. Pandora is a part of a network of identical instruments known as the Pandonia Global Network.

If instrument name or model is not available but documents show that specific chemical compounds or constituents or their properties were observed, can use instrument entry. Examples include: CO, CO2, NO, NO2, N2O, HNO3, HNO4, OH, H2SO4, CH3CN, O3, H2O, halocarbons, VOCs, nitrates, aerosols (including CCN), aerosol optical properties, etc...
