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 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 Met Office's 64 MHz ST (stratosphere-troposphere) wind profiler was installed at the Met Office South Uist range meteorological station, Hebrides, in May 2003. The radar complements the MST radar located near Abersywyth, providing greater vertical coverage than the other wind profiling radars in the Met Office's UK "Operational Upper Air Network." Operating at 64 Mhz, the South Uist 64 Mhz radar runs typically sounds from 1 to 13 km with a heigh resolution of either 150 or 400m, depending on the mode of operation. The site is located at 57.353 N, 7.375 W and at a height of 4 m above mean sea-level and has a WMO id of 03019. It had a beam angle of 15.0 degrees and is operated with an averaging period of 30 minutes. This dataset contains vertical wind profiles from the 64MHz wind profiler located at Camborne.

A Vaisala Radian LAP3000 1290 MHz wind profiler has been permanently located at the Met Office's site at the Dunkeswell airfield near Honiton in East Devon, and has been operational since February 1999. This was one of two such profilers deployed in the UK at that time as part of the Met Office's UK "Operational Upper Air Network." Operating at 1290 Mhz, Dunkeswell, like the other sites, is configured to operate in two modes. The low mode provides high resolution wind information up to 2km above the surface, while the high mode, with 210m resolution can see up to 8km under appropriate conditions.. The site is located at 50.87 N, 3.23 W and a height of 253 m above mean sea-level and has a WMO id of 03840. It has a beam angle of 15.5 degrees and is operated with an averaging period of 30 minutes. This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 1290MHz wind profiler located at Dunkeswell.

Synoptic charts from the Met Office's Cyclone Database, constructed from output stored in the database covering 2000-2005. 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. Database raw data available in its own dataset within this collection.

Met Office high resolution (2 second) radiosonde data from the South Uist 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 Natural Environment Research Council's (NERC) Mesophere-Stratosphere-Troposphere (MST) Radar Facility site at Capel Dewi, near Absersywyth, Wales, from November 1999 to March 2002. This deployment was to co-locate this UHF boundary layer wind profiler with the NERC MST VHF wind profiling radar - giving a combined coverage between the two instruments from around 300m to 20 km. 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 Capel Dewi site is located at 52.42 N, 4.01 W and a height of 92 m above mean sea-level. The site has a WMO id of 03501. 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 was subsequently deployed at South Uist and then at its present location on the Isle of Man. This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 915MHz wind profiler located at Capel Dewi.

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.

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 Stornoway station from 1990 to 2001. 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.
