As noted, the temperature sensor was intended primarily to monitor the temperature of the pressure sensor. No attempts were made to verify the absolute accuracy of the temperature reading. Even in the absence of measurement and calibration errors, the interpretation of this temperature is difficult. It emphatically was not the ice, snow, or air temperature. It was the temperature inside the buoy, and consequently integrated the ice, snow and air temperature, and the long and short wave length radiative fluxes and cooling by the wind. The buoy temperature is believed to have been within a few degrees of the ambient air temperature even during periods of direct solar radiation (Martin and Clarke 1978). A strong diurnal cycle, present in the raw data, especially during the spring, is suppressed in the daily averages reported below.
Buoy 1906 gave anomalously low temperatures in the Fairbanks test -- a result also apparent in data after deployment. A correction of +6.4 degrees C has been made to that buoy.
