The Meteorological Research Flight (MRF) was a Met Office facility, which flew a well-instrumented C-130 Hercules aircraft for atmospheric research purposes. This dataset contains airborne atmospheric and chemistry measurements taken on board the Met Office C-130 Hercules aircraft flight A308 for research purposes.

The University of Aberystwyth mobile ozone lidar data contain measurements of ozone mixing ratios and aerosol information. The data were collected at Chilbolton observatory, Hampshire on the 7th and the 8th of June 2005. The data collected on the 7th of June 2005 are of ozone mixing ratios only. The data collected on the 8th of June 2005 are of ozone mixing ratios, aerosol backscatter, and boundary layer height information.

The University of Leeds Sodar 2 dataset contains measurements of the scattering of sound waves by atmospheric turbulence at Alice Holt, Hampshire over the period from the 22nd of June 2005 to the 22nd of August 2005. The dataset contains measurements of wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

This dataset contains daily monthly average, N80 Gaussian gridded, pressure level, analysis timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from September 1957 to August 2002. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

The global radiation observation data contain hourly and daily radiation amounts, including those no longer being reported. The measurements of global solar irradiation amount, diffuse solar irradiation amount, direct irradiation amount, irradiation balance amount, and global horizontal illumination are recorded by observation stations worldwide and transmitted within SYNOP, HCM, AWSHRLY, MODLERAD, ESAWRADT and DRADR35 messages. The data span from 1947 to present.

This dataset contains 6-hourly monthly average, N80 Gaussian gridded, model level, analysis time step parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from August 1958 to September 2002. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

The Shoeburyness Field Trial: Investigation of Meteorological Effects on the Sound Propagation from a Helicopter Operating Near a Land Sea Interface Project was a QinetiQ applied research programme 3G23, funded by Ministry of Defence (MOD). The project duration was from April 2004 to March 2007 and had the aim to investigate noise modelling of helicopters with regard to long range sound propagation. The trial sought to understand more fully the meteorological effects on sound propagation over a land sea interface. This dataset collection contains measurements from the automatic weather station, which was used to gather standard meteorological measurements. The Universities Facility for Atmospheric Measurement (UFAM) automatic weather station was operated by the University of Salford.

The Meteorological Research Flight (MRF) was a Met Office facility, which flew a well-instrumented C-130 Hercules aircraft for atmospheric research purposes. This dataset contains airborne atmospheric and chemistry measurements taken on board the Met Office C-130 Hercules aircraft flight A445 for research purposes.

This dataset contains daily monthly average, N80 Gaussian gridded, model level, forecast timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from January 1958 to December 2001. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

Data were collected by various stations around the globe, not covered by other datasets within this collection, and cover the period from 1900 until 2000. These data are the Met Office's 'old' Land Surface Observation data and have been superseded by the MIDAS dataset collection. This dataset remains for historic purposes only. The data contain measurements of hourly and daily meteorological values, such as rainfall, sunshine duration, temperature, and wind speed. The MIDAS dataset supersedes this dataset and new users should apply for access to that by following the on-screen instructions. If necessary, you will be able to access this historic dataset once you have been granted access to the MIDAS data. The dataset contains the measurements of the following parameters: Sunshine duration Snow depth Visibility Wind speed and wind direction Temperature Cloud type Past and present weather
