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.

More Information (under review)
The 3 GHz Chilbolton Advanced Meteorological Radar (CAMRa) is the largest steerable meteorological radar in the world. The 25 metre dish is located at the Chilbolton Observatory in England (UK). It has dual-polarisation capability and full Doppler capability. The scan-type is usually 'ppi' (plan-position indicator, i.e. a horizontal scan) or 'rhi' (range-height indicator, i.e. a vertical scan). Chilbolton Observatory is operated by the Radio Communications Research Unit of CCLRC Rutherford Appleton Laboratory.
The characteristics of the radar are:
|Antenna diameter||25 metres|
|Peak power||560 kW|
|Pulse width||0.5 micro-sec|
|Pulse repetition frequency||610 Hz|
|System noise figure||1.3 dB|
|Range resolution||300 m or 75 m|
|Cross-polar isolation||-34 dB|
|Standard maximum slew rate||1 degree/sec|
|Unambiguous velocity||15 m/s|
