COBALD
Compact Optical Backscatter Aerosol Detector

The Compact Optical Backscatter Aerosol Detector (COBALD) is an in situ balloon-borne optical sensor developed at ETH Zürich. It detects aerosol backscatter at 455 nm and 940 nm using two light-emitting diodes (LEDs) as light sources. COBALD can provide aerosol backscatter profiles up to about 30 km. It has a measurement frequency of 1 Hz and a vertical resolution of 5 m.
