Instruments

Transmissometer

Supplied Description:

These data are from the 2 Wetlabs c-Star 25cm transmissometers used on the JGOFS NBP9711 profiling package: the 488nm c-star (SN CST-165B) and the 660nm c-Star (SN CST-166R). The transmissometer data were collected with a MER 2040.

Instrument Type

Generic Name: Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/124/

Generic Description:

A transmissometer measures the beam attenuation coefficient of the lightsource over the instrument's path-length. This instrument designation is used when specific manufacturer, make and model are not known.
