The sensors on the Tethered Spectral Radiometer Buoy (TSRB) (S/N 003) measure downwelling irradiance above the sea surface, upwelling radiance just below the sea surface, and the water temperature.  The irradiances and radiances are measured at seven wavebands with bandpasses of approximately 10 nm, centered at:

412, 443, 490, 555, 670, 684 and 700 nm.

Measurements were made at a frequency of 6 Hz, with time stamps from the logging computer added to the data file every second.  Further information on this instrument is available from Satlantic, Inc.

This instrument was calibrated by Satlantic, Inc. before deployment.
