blc: Belfort Laser Ceilometer

BLC is currently inactive and/or retired. This instrument was replaced by a Vaisala 25k Ceilometer in the summer of 2000.

The Belfort laser ceilometer (BLC) Model 7013C field unit is a self-contained, ground-based, optical, active remote sensing instrument with the ability to detect and process several cloud-related parameters. These parameters include cloud height, extinction coefficient, cloud layers and time/date reference information. The ceilometer system detects clouds by transmitting pulses of infrared light vertically into the atmosphere. The receiver telescope detects scattered light from clouds and precipitation.
