The Met Office have operated a network of wind profiling lidars at various sites around the British Isles since the first was installed in 1998, following the installation of the NERC MST radar near Aberystwyth. This datasets collection contains the available 30 minute averaged wind profile data from these sites made available for research by the academic community and included parameters such as measurements of the zonal, meridional and vertical components of winds, signal to noise ratio and spectral width. The data are from boundary layer UHF wind profilers located at Camborne (915 Mhz), Dunkeswell (1290 Mhz) and Wattisham (1290 Mhz) and a Stratosphere-Troposphere (ST) VHF radar at South Uist operating at 64 Mhz. A fourth UHF radar operated at 915 Mhz was operated at the NERC MST Radar site at Capel Dewi, near Aberystwyth, between November 1999 and March 2002; it was then relocated to South Uist until May 2005 ahead of and during the commissioning of the 64 Mhz radar, before being relocated to its present location on the Isle of Man. An additional Degreane wind profiler has since been purchased by the Met Office and is deployed at the Chilbolton Observatory, but data from this instrument are not presently part of this dataset. This dataset contains wind profiler data from: - Camborne (from 1998) - Dunkeswell (from 1999) - Wattisham (2001 to present) - Aberystwyth (Capel Dewi, 1999 to 2002) - South Uist (915MHz, 2003 to 2004) - South Uist (64MHz, from 2004) - Isle of Man (2005 to 2008 and since 2010). Data from these wind-profilers, and from the NERC MST Radar, are used operationally by the Met Office for numerical weather prediction. They additionally receive data from up to another 15 wind-profiling systems throughout Europe as part of the CWINDE (COST Wind Initiative for a Network Demonstration in Europe) project. A map showing the locations of the wind profilers is available on the CWINDE website. Data from wind profilers is also routinely transmitted across the Global Telecommunication System (GTS) according to standards defined by the World Meteorological Organisation (WMO). Those data can be found in the Met Office MetDB dataset also held by the CEDA.

This dataset contains corrected observations (motion and translational movement) from a WindCube V2 Lidar (Leosphere). The instrument was mounted on the NATO Research Vessel Alliance during Iceland Greenland Seas Project (IGP) campaign in February–March 2018. The Iceland Greenland seas Project (IGP) was an international project involving the UK, US a Norwegian research communities. The UK component was funded by NERC, under the Atmospheric Forcing of the Iceland Sea (AFIS) project (NE/N009754/1).

Data were collected from the 14th of February 2009 to the present by the Leosphere EZ polarization lidar at Chilbolton Observatory, Hampshire. The dataset contains plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. The dataset contains: Plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. Atmospheric backscatter light intensity (raw data) Solid angle and background calibrated data Vertical backscatter and extinction profile Vertical Aerosol profile Planetary Boundary Layer and residual layer heights Semi-transparent cloud height and top Optical depth integrated over whole Lidar range Dynamic structure of the atmosphere (e.g gravity waves...) Asphericity information on the particle in order to discriminate some particles from others (soil dust from other aerosol, ice/water phase of the clouds…)

Data from the Met Office's laser cloud base recorders network (LCBRs), or ceilometers, returns a range of products for use in forecasting and hazard detection. These include cloud base height and also backscatter profiles. The backscatter profiles can allow detection of aerosol species such as volcanic ash where suitable instrumentation is deployed. The Met Offices operational LIDARNET network consists of Vaisala CT25k and CL31 ceilometers and the Jenoptik CHM15k Nimbus. In addition, this dataset also contains data from the development ceilometers operated by the Met Office.

CWAVE was a measurement campaign at the CCLRC-Chilbolton Observatory; it supported activities associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office. Access to such a data set allowed unprecedented comparisons between observed and modelled data. The core observing period was 16th June to 11th July 2003. The Aims of CWAVE were: -Validation and inter-comparison of cloud and water vapour measurements from satellite, with remotely sensed ground based measurements of cloud parameters and water vapour. -Comparison of measured cloud parameters and water vapour, with results from high resolution Unified Model (UM) run by the Met Office.

This dataset collection contains data from the ISB52 Improved Air Quality Forecasting project. The aim of the project was to develop a better understanding of air flow within the atmospheric boundary layer by gathering 3-dimensional air flow information using two identical Doppler lidars. The project compared parameters derived from the dual Doppler lidar measurements with inputs used in the UK Met Office air quality forecasting model. Field experiments were undertaken in March 2003 at Malvern and in July 2003 at RAF Northolt, West London, UK.
