We present the results of a comparison of measured water vapour content above Mauna Kea obtained using the Submillimetre Common User Bolometer Array (SCUBA) and an infrared radiometer at the James Clerk Maxwell Telescope. We show that for most weather conditions the Infrared Radiometer for Millimetre Astronomy (IRMA) produces results that correlate well with the SCUBA measurements. However, for nights with thick cirrus cover, the IRMA results deviate from those obtained with SCUBA.
