Instrument: INTA Forward Scattering Spectrometer Probe 100-ER

Name INTA Forward Scattering Spectrometer Probe 100-ER
Acronym FSSP-100ER-INTA
Manufacturer Particle Measuring Systems
Operated by INTA
Operated onboard

Instrument type

Name Cloud Droplet Size Spectrometer
Acronym Cloud Droplet Spectrometer

Principle of operation

Measured parameter Cloud droplet size spectra, number concentration and water content,
Operating principle

Optical probe. Cloud droplets pass through sample volume, where they scatter a laser beam. Scattered light picked up by detectors allowing size to be determined. Bulk quantities such as total droplet number concentrations, liquid water content, or effective droplet radius can be derived.
