This dataset contains scan data from the National Centre for Atmospheric Science Atmospheric Measuring Facility's mobile X-band radar between 1st November 2016 to 4th June 2018 at Chilbolton Facility for Atmospheric and Radio Research (CFARR), UK, as part of ongoing long-term observations made by the NERC National Centre for Atmospheric Science (NCAS). The radar transmits pulses of electromagnetic radiation and measures the amount of energy backscattered to the receiver from which the location and intensity of precipitation, radial winds and polarisation parameters can be calculated.

Parameters available in these data files include:

dBZ - equivalent reflectivity factor;

V - radial velocity;

W - spectral width;

ZDR - differential reflectivity;

KDP - specific differential phase shift;

PhiDP - differential phase shift;

RhoHV - co-polar cross correlation coefficient;

SQI - signal quality index or normalized_coherent_power.

A complete list of all available parameters is available on the CEDA data catalogue record for this dataset.

The sur files contain a volume of scans at different elevation angles between 0 and 90 degrees, approximately every 5-6 minutes.

The rhi files contain a single cross-section scan at a given azimuth and an elevation range of 0 to 180 degrees, every 5-6 minutes.

The data are available as netCDF files to all registered CEDA users under the Open Government License.
