The development of a new 22 GHz microwave spectrometer for monitoring middle atmospheric water vapour at polar latitudes
Water vapour is a crucial element of the climate system. Accurate observations of stratospheric humidity are needed in the equatorial belt, where water vapour crosses the tropopause, and in the Polar regions, that are affected the most by climate change trends [IPCC, 2007; Solomon et al., 2010].
