The Met Office installed a Vaisala Radian LAP3000 915 MHz wind profiler near Meary Veg close to the Ronaldsway Aiport on the Isle of Man in 2005, relocating the instrument from its former deployment on South Uist which itself followed a deployment at the MST radar site at Capel Dewi near Aberystwyth. The deployment on the Isle of Man was an integral part of the Met Office's UK "Operational Upper Air Network." Operating at 915 Mhz, it provides high resolution wind information from just above the surface (around 300m) up to a maximum of 8 km, depending on the atmospheric conditions. The site is located at 54.26 N, 4.37 W and a height of 55 m above mean sea-level and has a WMO id of 03203. 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 dataset contains vertical wind profiles from the Vaisala Radian LAP3000 915MHz wind profiler located at the Isle of Man.

Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Particle Sensor from 2009 to present. During this time the particle sensor was at Chilbolton, Hampshire, whilst previously it had been positioned at Sparsholt College, Hampshire. The dataset contains measurements of the size of individual particulates including rain, snow, and hail, as well as estimates of drizzle, total rainfall and liquid water content.

Ozone and water vapour in the tropopause region was an Upper Troposphere Lower Stratosphere (UTLS) Round 3 project led by Dr G. Vaughan, Dr J.A. Whiteway, Physics Department University of Wales, Aberystwyth and Dr R.L. Jones, Department of Chemistry, University of Cambridge. Dataset contains Balloon-borne simultaneous measurements of ozone and water vapour in the tropopause region. The flights are targeted as far as possible at different air masses in the lower stratosphere over Aberystwyth, with a particular emphasis on north-westerly jet streams. Air at the base of the stratosphere, within 1-2 km of the tropopause, was considered intermediate in character between stratosphere and troposphere. The ozone concentration increases steeply with height from ~80 ppbv at the tropopause to several hundred ppbv 2 km above it. The water vapour concentration was more variable, but generally decreases from ~100 ppmv at the tropopause to the standard 5-6 ppmv in the same height region. Other tracers of tropospheric origin behave likewise, which means that the lowest 2 km of the stratosphere is of quite a different chemical character to the remainder of the stratosphere. Water vapour was a key molecule in the UTLS region, and one that has traditionally been poorly measured above the tropopause. Even though the newest generation of radiosonde at that time (e.g. the Vaisala RS90) performed much better than its predecessors in the upper troposphere it still did not measure adequately in the stratosphere. The MOZAIC humidity sensor was of this type, and was also unable to extend into the stratosphere; indeed, it cannot measure reliably below 100 ppmv in the upper troposphere. Satellite instruments extend water vapour profiles into the UTLS region but their limited resolution in a region of strong vertical gradients limits their value. Measurements of UTLS humidity have therefore relied on in-situ research instrumentation, either balloon-borne or aircraft-borne. Aircraft and large balloons are expensive and cannot provide a proper climatology for water vapour, and the long sequence of NOAA frost-point hygrometer profiles do so only in one location (Boulder). This project seeked to develop a small, relatively cheap package to measure water vapour and ozone in the region around the tropopause. The measurement phase of the project consisted of four month-long campaigns, for June, September and December 2001 and March 2002. An average of three flights a week were conducted during these periods - a total of 48 flights. These flights were targeted as far as possible, at different air masses in the lower stratosphere over Aberystwyth, with a particular emphasis on north-westerly jet streams. Forecast charts have been used to identify suitable conditions (350 K potential vorticity forecasts from ECMWF were available from NILU, Norway for 1 and 2 days ahead).

HIRDLS was a joint US-UK development effort, with sponsorship by the British National Space Centre and the Natural Environment Research Council in the UK, and by NASA in the US. HIRDLS was an mid-infrared limb-scanning radiometer (21 channels from 6.12 to 17.76 µm and provides sounding observations to observe the lower stratosphere with improved sensitivity and accuracy. HIRDLS was carried on the Aura mission, part of the A-train procession of polar orbiting satellites forming part of NASA's Earth Observing System (EOS). This dataset collection contains data of the global distributions of temperature, clouds, aerosols, and 10 trace species O3, H2O, CH4, N2O, NO2, HNO3, N2O5, CFC11, CFC12, and ClONO2 in the stratosphere and upper troposphere at high vertical and horizontal resolution in the Earth's atmosphere between about 8 and 100 km, from the High Resolution Dynamics Limb Sounder (HIRDLS) instrument. The instrument provides high vertical resolution information despite the fact that the optical beam is partially obstructed between the scan mirror and the aperture, probably by a piece of inner lining material that became detached during launch. HIRDLS science-team members have produced correction algorithms that make use of the partial view of the atmosphere (vertical scans around azimuth angle of 47 degree line of sight to the orbital plane, on the side away from the sun). In spite of this anomaly, HIRDLS has retained most of its scientific capabilities to support the Aura Mission. HIRDLS was carried on the Aura mission, part of NASA's Earth Observing System (EOS). Aura was launched on 15th July 2004 at 11:01:59 a.m. BST from Vandenberg Air Force Base, California.

This dataset contains output data from a number of models from the UK Met Office Hadley Centre which was processed into text files at the Climate Research Unit at the University of East Anglia. The data extraction was intended for use by the Climate Impacts Community (and was funded by the UK Departement of Environment Food and Rural Affairs, Defra). Output from each model is stored in a separate directory in the BADC archive, and the majority of the data comes from experiments performed using the Hadley centre Coupled Model, Version 3 (HadCM3). Note that is dataset is kept for historical purposes only. More consistent and complete HadCM3 data is available from the main British Atmospheric Data Centre (BADC) HadCM3 archive.

This dataset collection comprises Ungridded Brightness Temperature (UBT) products from both ATSR-1 and ATSR-2 on the respective ERS-1 & 2 platforms. The ATSR (Along Track Scanning Radiometer) is an imaging radiometer providing images of the Earth from space. The ERS (Earth Resources Satellite) was the first ESA satellite observation programme comprising 2 polar orbiters. The ERS-1 and 2 programmes commenced in 1991 and 1995 respectively with ERS1 ceasing operations in 2000 and ERS-2 in 2011. The UBT data is an ungridded brightness temperature/reflectance product in the SADIST-2 data format. The product contains ungridded, calibrated brightness temperatures or reflectances from all or some of the ATSR-1/ATSR-2 detectors. Although the product remains ungridded, it may optionally contain pixel latitude/longitude positions, and/or pixel X/Y (across-track/along-track) co-ordinates. Ungridded products contain pixels in the ATSR scan geometry. There is a correspondence between the contents of a record and the contents of an ATSR instrument scan. ATSR data is notable in that it incorporated 2 look directions (nadir and forward) to aid in atmospheric correction and also incorporated consistent calibration for each scan/scene. ATSR-1 and 2 data are available at CEDA to any registered UK user with correct authorisation from the ATSR-1/2 Science Team, and NERC Award reference. Non NERC users should have ESA Category 1 clearance. However, users are encouraged to use the ATSR-1/2 in the latest AATSR multimission format in preference to this UBT data. CEDA remains the primary archive for this data.

The International Satellite Land Surface Climatology Project, Initiative II (ISLSCP II) is a follow on project from The International Satellite Land Surface Climatology Project (ISLSCP). ISLSCP II had the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP). This dataset contains: *Albedo *Ecosystem roots *Historic crop land and land cover *Potential vegetation *Continuous vegetation The data are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public.

The CLOUDMAP 2 project cloud products include cloud top pressure, height, phase, fraction, effective radius and optical depth derived using a variational analysis method applied to data from the Along Track Scanning Radiometer-2 (ATSR-2) over Europe. These data are the result of a contract to Eumetsat for application to the Spinning Enhanced Visible Infra-Red Imager (SEVIRI) and partly under the European Framework 5 CLOUMAP2 project.

These data are part of the NERC Clouds, Water Vapour and Climate (CWVC) programme. With a diameter of 25 metres the 3 GHz CAMRa at Chilbolton Observatory (UK) is the largest steerable meteorological radar in the world. Polarisation and Doppler data are stored in netCDF format for 30 March 1999, 9 June 2000, 20 October 2000, 21 November 2000, and 28 February 2001. Quicklook images are also available.

The International Satellite Land Surface Climatology Project (ISLSCP) has the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP). The ISLSCP II datasets are compiled in four key areas: land cover, hydrometeorlolgy, radiation and soils. They are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public. ISLSCP is one of several projects of the Global Energy and Water Cycle Experiment (GEWEX), and has the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. ISLSCP was established in 1983 under the United Nation's Environmental Programme to promote the use of satellite data for the global land surface data sets needed for climate studies. In 1994, ISLSCP produced a five-volume CD-ROM collection of global data sets to support energy, water and biogeochemical cycling studies, covering 1987 - 1988 - the ISLSCP I Initiative. The ISLSCP I data sets are available via the BADC ISLSCP I page. The ISLSCP working group meet regularly to assist Goddard Space Flight Center staff to coordinate production and publication of the various data sets in the data collection.
