Single-polar products from the Met Office's Holehead C-band rain radar, Stirling, Scotland. Data include reflectivity (from April 2012), Doppler (from August 2012) and CPAPR (from August 2012) products. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

Dual-polar products from the Met Office's Jersey C-band rain radar, Channel Islands. Data from this site include augmented ldr (linear depolarisation ratio) and zdr (differential reflectivity) scan data (both long and short pulse) available from June 2018 at present. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

Single-polar products from the Met Office's Clee Hill C-band rain radar, Shropshire, England. Data include reflectivity and augmented Doppler products from April 2012 and June 2008 respectively. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

Single-polar products from the Met Office's Deanhill C-band rain radar, Whiltshire, England. Data include reflectivity and augmented Doppler products from April 2012 and June 2008 respectively. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

Dual-polar products from the Met Office's Chenies C-band rain radar, Hertfordshire, England. Data include augmented ldr and zdr scan data (both long and short pulse). The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

1 km resolution data from the NIMROD system data describe rain-rate observations taken at Hameldon, Lancashire, by NIMROD, which is a very short range forecasting system used by the Met Office. 1 km rain rate data are available from 2011 until present. Radar images from the C-band (5.3 cm wavelength) radar are received by the Nimrod system 5 minute intervals.

Dual-polar products from the Met Office's High Moorsley C-band rain radar, County Durham, England. Data from this site are availlable from August 2018 at present, although the radar has been producing augmented lrd scan data previous to this time. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

1 km resolution composite data from the Met Office's UK rainfall radars via the Met Office NIMROD system. The NIMROD system is a very short range forecasting system used by the Met Office. Data are available from 2004 until present at UK stations and detail rain-rate observations taken every 5 minutes. Each file has been compressed and then stored within daily tar archive files. The precipitation rate analysis uses processed radar and satellite data, together with surface reports and Numerical Weather Prediction (NWP) fields. The UK has a network of 15 C-band rainfall radars and data form these are processed by the Met Office NIMROD system. Please note CEDA are not able to fulfil requests for missing data from this archive. The data may be available at a cost by contacting the Met Office directly with required dates. It is worth contacting the CEDA first to check if the reason for the gap is already identified as being due to the data not existing at all. CEDA does not support reading software but programs written by the community to do this task in IDL, Matlab, FORTRAN and Python are available in the dataset software directory. The data files contain integer precipitation rates in unit of (mm/hr)*32. Each value is between 0 and 32767. In practice it is rare to see a value in excess of 4096 i.e. 128 mm/hr. At 10:00 on 14 June 2005, the 1 km composite data files became larger with 2175 rows by 1725 columns compared to the previous 775 rows by 640 columns. From 14:55 on 30 August 2006, the 1 km composite data files are gzipped files. From 13 Nov 2007, the 1 km composite is derived directly from processed polar (600m x 1 degree) rain rate estimates and there is more detail in the rain structure.
