Abstract
A 183GHz water vapour radiometer is installed at the JCMT, but is not currently used for active atmospheric calibration. With the installation of the SCUBA-2 submillimetre camera, it is desirable to provide more accurate and time-sensitive calibration at specific wavelengths. It is shown here that the 183GHz water vapour monitor data can be used to calculate the atmospheric opacity over small time-scales, directly along the line-of-sight of the instrument. These data will be used to identify the potential for improvement in existing calibration schemes, and the requirements of such a system if used with an instrument such as SCUBA-2.
