Data from the Met Office's Cyclone Database, consisting of flat files from the database covering 2000-2005 with associated charts. The database holds lists of cyclones, their types and structural information about each cyclone and associated features as derived from analysis of the UK Met Office Unified Model.

Met Office high resolution (2 second) radiosonde data from the St Helena Bottoms Wood station from 1999 to present. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

The Met Office deployed a Vaisala Radian LAP3000 915 MHz wind profiler at the Met Office's meteorological station on the South Uist range, Hebredies, from January 2003 to July 2004. This deployment was ahead of the installation of the Met Office's 64 MHz Stratosphere-Troposphere (ST) radar at the same site and provided a period of colocated measurements from the two instruments from May to July 2004. At the time the Met Office's 915 Mhz wind profiler was an integral part of the Met Office's UK "Operational Upper Air Network", providing high resolution wind information from just above the surface (around 300m) up to a maximum of 8 km, depending on the atmospheric conditions. The South Uist site is located at 57.353 N, 7.375 W and a height of 4 m above mean sea-level. The site has a WMO id of 03019. The instrument's hight resolution is 60/200 m depending on the operational mode. It has a beam angle of 15.0 degrees and is operated with an averaging period of 30 minutes. This instrument had been previously deployed at the Capel Dewi site near Aberystwyth and was subsequently deployed to its present location on the Isle of Man in 2005. This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 915MHz wind profiler located at South Uist.

Met Office high resolution (2 second) radiosonde data from the Beaufort Park airfield, Bracknell from 1999. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

Met Office high resolution (2 second) radiosonde data from the Castor Bay airfield, Northern Ireland from 2002 to present. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

The CLIMAT reports describe monthly climate observations by WMO (World Meteorological Organisation) Climate Reference Stations of which there are currently 20 in the UK and some 400 worldwide. The observation stations measure parameters such as monthly mean air temperature, monthly mean vapour pressure, total sunshine for the month, and total precipitation for the month. NOTE - these data are provided as-is from the Met Office and so will need converting form the CLIMAT message format.

Met Office high resolution (2 second) radiosonde data from the Hillsborough station from 1990 to 2002. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

Met Office high resolution (2 second) radiosonde data from the Crawley station, near London, from 1990 to 1991. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

Met Office high resolution (2 second) radiosonde data from the Aughton station near Liverpool, UK, from 1990 to 1996. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

Met Office high resolution (2 second) radiosonde data from the Watnall station from 2000 to 2013. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.
