Chilbolton Advanced Meteorological Radar (CAMRa) data, part of the Clouds, Water Vapour and Climate (CWVC) programme

Status: Not defined
Publication State: published

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.

More Information (under review)


Introduction
These data are part of the NERC Clouds, Water Vapour and Climate (CWVC) programme.

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:

Frequency 3.075 GHz
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
Beamwidth 0.28 degrees
Range resolution 300 m or 75 m
Cross-polar isolation -34 dB
Standard maximum slew rate 1 degree/sec
Unambiguous velocity 15 m/s


Data Access

The CWVC CAMRa dataset is now public. Please acknowledge the source of the data in any publication.


Availability of data and file format

Data and quicklook images, for 30 March 1999, 9 June 2000, 20 October 2000, 21 November 2000, 28 February 2001, are available.

Data are stored in the BADC CWVC Mixed Phase Clouds data project archive.

Who to contact

If you have queries about these pages or about obtaining the CWVC-CamRA data from the BADC then you should contact BADC Support. Your query should be answered within one working day. When follow-up work is required, the BADC support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.
