Time-Lapsed Cloud Video (TLCV)

Note: This instrument is currently inactive and/or retired.
Active Dates: 9/15/1997 to 9/14/2001

Instrument Categories: Cloud Properties

General Overview

The time-lapsed cloud video (TLCV) camera provides a record of sky conditions by recording color images of an approximately 100-degree field of view, centered on the zenith. The time interval between images may be adjusted to a wide range of periods, but typically is set to 4 or 8 seconds, thus providing a high time resolution record of cloud conditions. Data is stored to S-VHS tape for archival.

Primary Measurements Taken

The following measurements are those considered scientifically relevant. Refer to the netCDF File Header Descriptions (Data Object Design Files) for the list of all available measurements, including those recorded for diagnostic or quality assurance purposes.
