Single-polar products from the Met Office's Hameldon Hill C-band rain radar, Lancashire, England. Data include reflectivity and augmented Doppler products from June 2005 and December 2012 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 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.
Dual-polar products from the Met Office's Cobbacombe Cross C-band rain radar, Devon, 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.
UK Met Office charts analyses pertaining to Mean Surface Level Pressure and 24 hour Weather Frontal Forecasting for the UK and Western Europe for the 00 and 12UT forecast runs. The charts in this dataset, at time steps at T+00, 24, 48 and 72 hours, have been produced by the Met Office's SWIFT system using VisualWeather, following a switch from the feed provided by the Met Office's GCPS Commercial System (see related dataset). The data in this collection cover the period 30th June 2014 to present, though initially with some data gaps.
Single-polar products from the Met Office's Druim a'Starraig C-band rain radar, Isle of Lewis, Scotland. Data include reflectivity (from April 2012), CPA (from October 2011) and CPAPR (from September 2009). Dual-polar products from this site are available from 2014. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.
The ozone profiler data describes weekly measurements reported by an ozonesonde at a fixed land station at Lerwick. The dataset contains atmospheric profiles of ozone concentrations. The data are measured from the surface to up to 40 km, and transmitted from the ozonesonde via a radio link to a ground receiving station.
The Chilbolton Observatory, Hampshire, have had a Vaisala CT75K lidar ceilometer deployed since 13th September 1996. This dataset contains measurements of the range of first, second, and third cloud base from the lidar and attenuated backscatter coefficients of aerosols within the atmosphere. Plots of the attenuated backscatter coefficient at different heights are also available. The instrument has been regularly calibrated using the method described by O'Connor, Ewan J., Anthony J. Illingworth, Robin J. Hogan, 2004: A Technique for Auto-calibration of Cloud Lidar. J. Atmos. Oceanic Technol., 21, 777–786. doi: http://dx.doi.org/10.1175/1520-0426(2004)021<0777:ATFAOC>2.0.CO;2 . Prior to April 2014 this technique had been applied manually, but from 2014 this was automated to provide a routine, automated application of O'Connor et al's calibration technique. This also highlighted an instrument calibration drift not previously spotted in earlier data and so a corrected data have been added to the archive for the following periods (denoted by "_cor1" in the filename): 1st July 2003 – 31st December 2003, January 2006 to December 2012 and February and March 2013. Users should see the data quality notes for further details. This dataset incorporates the earlier published and citable 1996 - 2013 collection of lidar data, but continues this dataset to present
1 km resolution rain rate data from Met Office's Cobbacombe Cross C-band rain radar, Devon, England as part of the NIMROD, 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 respectively.
Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Sensor from 2001 to present at Chilbolton, Hampshire. The standard meteorological measurements are made at Chilbolton in support of all experiments at the Observatory. The data are automatically recorded every 10 seconds from a range of different sensors. The dataset contains measurements including temperature, dew point, pressure, wind speed and wind direction.
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.
