Abstract
Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Radiometrics Radiometer from the 23rd of August 2007 to the present at Chilbolton, Hampshire. The dataset contains measurements of the total liquid water at zenith, together with the vertical profile of water vapour density.
Accuracy of integrated water vapour (IWV) retrieval: ~1 – 2 mm
Accuracy of total liquid water path (LWP) retrieval: ~15% in non-precipitating conditions.
