Abstract

These data are part of the NERC Clouds, Water Vapour and Climate (CWVC) programme. With a diameter of 25 metres the 3 GHz CAMRa at Chilbolton Observatory (UK) is the largest steerable meteorological radar in the world. Polarisation and Doppler data are stored in netCDF format for 30 March 1999, 9 June 2000, 20 October 2000, 21 November 2000, and 28 February 2001. Quicklook images are also available.
