shortwave and longwave all-wave radiometers were installed on the flying
bridge of the ship to monitor incident radiation. They were positioned
to minimize shadowing from the superstructure of the ship. A correction
of 4.06% was made to the
raw shortwave values to account for modest amount of shadowing. The
longwave correction was a big more complex as it needed to take into
account the both air temperature and the sky temperature. They were connected to a Campbell Scientific datalogger for autonomous data collection and storage. Measurements were made every 5 minutes. The domes were susceptible to condensation and riming. They were checked and cleaned every two hours as part of the ice watch routine. |
