The Upper Atmosphere Research Satellite (UARS) was the first major element in NASA's Mission to Planet Earth. It was designed to make a systematic study of the stratosphere and provide new data on the mesosphere and thermosphere. The satellite was launched on 12th September 1991. This dataset contains standard data concerning stratospheric temperature, geopotential height and wind components produced by the upper atmosphere research satellite data assimilation system at the UK Met Office. The data assimilation system is a development of the scheme used at the Met Office for operational weather forecasting, which has been extended to cover the stratosphere. The primary product is a daily analysis (at 1200 UTC) which is produced using operational observations only. For short periods of particular interest the analyses are available at 6-hourly intervals. Assimilation experiments using UARS (Upper Atmosphere Research Satellite) data in addition to operational meteorological observations have been carried out for limited periods.

The Met Office's research unit based in Cardington, Bedfordshire, study boundary-layer meteorology and surface processes to help with the development of numerical weather prediction methods. These are used in a number of ways including the development of physical parameterisation schemes. Surface meteorological data and high resolution radiosonde data are collected from the Met Office's research site and elsewhere. The dataset collection contains recorded surface measurements timed at 1, 10 and 30 minute intervals and measured by instruments mounted on the surface, 10, 25 and 50 metre masts. Radiosonde data are available at various locations depending on the deployment of the equipment. The facility continuously operates a comprehensive suite of surface, sub-surface, mast and tethered balloon mounted instrumentation. Various items of instrumentation, as well as the radiosonde and tethered balloon equipment, can also be deployed elsewhere in support of off-base measurement campaigns.

The global model producing this data was updated on July 11th 2017. Data from this date has an increased resolution of N1280L70: 2560 latitude x1920 longitude and vertical 70 levels (model top 80 km), see the documentation for full details.
