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 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.

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.

Dual-polar products from the Met Office's Crug-y-Gorllwyn C-band rain radar, Carmarthen, Wales. Data from this site include augmented ldr (linear depolarization ratio) and zdr (differential reflectivity) scan data (both long and short pulse), available from August 2018 to present. 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 Castor Bay C-band rain radar, Belfast, Northern Ireland. 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.

5 km resolution data from the NIMROD system data describe rain-rate observations taken at Clee Hill, Shropshire, by NIMROD, which is a very short range forecasting system used by the Met Office. 5 km rain rate data are available from February 2006 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 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.

The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

The Aircraft Meteorological Data Relay (AMDAR) measurements describe hourly observations from aircraft across the world during all stages of flight. The observations cumulate into 160,000 reports a day, giving measurements of parameters such as aircraft characteristics, wind speed and direction, degree of turbulence, and air temperature. The data are collected by observation stations worldwide and transmitted within the AMDAR message, which prior to March 1992, was known as ASDAR(Aircraft to Satellite Data Relay).
