Abstract : Measurements were made with a group of sensors for 37 days at the end of a dock in Vineyard Sound. The sensors included: a thermistor in an R.M. Young aspirated air temperature radiation shield, a thermistor in an R.M. Young multiplate shield, wind speed and direction, and solar irradiance. For the last eight days we also included a WHOI built cylindrical radiation shield. For wind speeds above 2 m/s, the multiplate shield had an RMS error relative to the aspirated shield of 0.2-0.3 C during day-light hours. Adding a correction linear in solar irradiance decreased the error by a factor of one third to one half. The cylindrical shield appears to have performed better than this but there was insufficient data to support this conclusion statistically.
