Fig. 2. Diurnal variation in internal temperature of transparent and
painted buoy hulls compared with NWS-measured air temperatures.
Data shown are from an experiment in 1976 at Barrow. The insulated
buoy hulls used in 1977 had internal temperature amplitudes slightly
smaller than the air temperature, with phase lag of several hours.
Twenty-day averages throughout the test period show that the sensors were
free from drift for four months (Fig. 5). The mean pressure differences between
buoys and NWS data are 0.08 and 0.25 mb and are probably due to small calibration
shifts after the buoys left the laboratory but before they were deployed
in the field.
