Aircraft measurements of water vapour continuum absorption at millimetre wavelengths
Abstract In preparation for the future AMSU‐B mission, measurements of clear‐air radiative transfer at 89 and 157 GHz were made using a radiometer operating on the C‐130 aircraft of the UK Meteorological Research Flight. Observations of water vapour and oxygen absorption in arctic, middle latitude a...
