  • Historic land surface observations data from the Met Office station network. Data are available for the period 1900 to 1999 for daily measurements. Hourly observations are for now available back to January 1985. The dataset comprises daily and hourly weather measurements, hourly wind parameters, max and min air temperatures, soil temperatures, sunshine duration and radiation measurements and hourly and daily rain measurements. This dataset has been SUPERSEDED BY THE NEW MIDAS Land Surface Stations data (1853-current). It has been retained for reference purposes. Users with access to the MIDAS Land surface stations dataset automatically have access to this dataset as well. The daily data are available online from UK stations in 110 UK regions (mainly counties) over the period 1853 to July 2000. The hourly data are for available from stations in the 110 UK regions also covered by the daily data from 1983 to July 2000.

  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset contains daily micro-meteorological data from the experimental plots at the Climoor field site in Clocaenog forest, NE Wales. It runs from 15/7/1999 until 31/12/2013, and contains air temperature, soil temperature at 2 depths (5 and 20cm) as well as soil moisture. The dataset has been quality checked, and incorrect or missing values removed, data has not been infilled. Full details about this dataset can be found at https://doi.org/10.5285/4260dc49-764f-4ba5-b215-dab7eaaf35c8

  • The UK daily temperature data describe maximum and minimum temperatures (air, grass and concrete slab) measured over a period of up to 24 hours. The measurements are recorded by observation stations across the UK and transmitted within NCM or DLY3208 or AWSDLY messages. The data span from 1853 to present.

  • The UK daily temperature data contain maximum and minimum temperatures (air, grass and concrete slab) measured over a period of up to 24 hours. The measurements were recorded by observation stations operated by the Met Office across the UK and transmitted within NCM, DLY3208 or AWSDLY messages. The data span from 1853 to 2018. For details on measurement techniques, including calibration information and changes in measurements, see section 5.2 of the MIDAS User Guide linked to from this record. Soil temperature data may be found in the UK soil temperature datasets linked from this record. This version supersedes the previous version of this dataset and a change log is available in the archive, and in the linked documentation for this record, detailing the differences between this version and the previous version. The change logs detail new, replaced and removed data. This dataset is part of the Midas-open dataset collection made available by the Met Office under the UK Open Government Licence, containing only UK mainland land surface observations owned or operated by the Met Office. It is a subset of the fuller, restricted Met Office Integrated Data Archive System (MIDAS) Land and Marine Surface Stations dataset, also available through the Centre for Environmental Data Analysis - see the related dataset section on this record. Currently this represents approximately 95% of available daily temperature observations within the full MIDAS collection.

  • The UK daily rainfall data contain rainfall accumulation and precipitation amounts over a 24 hour period. The data were collected by observation stations operated by the Met Office across the UK and transmitted within the following message types: NCM, AWSDLY, DLY3208 and SSER. The data spans from 1853 to 2019. Over time a range of rain gauges have been used - see section 5.6 and the relevant message type information in the linked MIDAS User Guide for further details. This version supersedes the previous version of this dataset and a change log is available in the archive, and in the linked documentation for this record, detailing the differences between this version and the previous version. The change logs detail new, replaced and removed data. This dataset is part of the Midas-open dataset collection made available by the Met Office under the UK Open Government Licence, containing only UK mainland land surface observations owned or operated by Met Office. It is a subset of the fuller, restricted Met Office Integrated Data Archive System (MIDAS) Land and Marine Surface Stations dataset, also available through the Centre for Environmental Data Analysis - see the related dataset section on this record. A large proportion of the UK raingauge observing network (associated with WAHRAIN, WADRAIN and WAMRAIN for hourly, daily and monthly rainfall measurements respectively) is operated by other agencies beyond the Met Office, and are consequently currently excluded from the Midas-open dataset. Currently this represents approximately 13% of available daily rainfall observations within the full MIDAS collection.

  • The Met Office WOW V1 dataset contains observations from all Public Weather Stations (PWS) contributing to WOW (Weather Observations Website) within Europe. The dataset is for a single year (2020), made available for use within the EUMETNET Sandbox project. EUMETNET (a grouping of 31 European National Meteorological Services) instigated the EUMETNET Sandbox project to bring novel observations and observations from technology trials and field campaigns to the research community to enable R&D activities. The data are not quality controlled and are presented in the format provided by the Met Office. The data are provided in a single file per month. The data were extracted from the WOW database using a latitude/longitude bounding box (North West corner 90N 70W to South East corner 10N 40E) so there are a small number of stations outside of Europe present. The meteorological values are unchanged from those extracted from the WoW archive. For example, there is no Quality Control of the data, no calibration of the instruments and no unit conversions have been applied. The data were extracted from the WoW archive by the Met Office operators of the WoW system. The data have not been manipulated to meet any international data format standards. The file names have been modified, from those provided by the Met Office, to contain location, data and status information. The records for each station are comma separated. Not all sites report all variables, nor at all times. In most cases only the principle meteorological variables, e.g., Air temperature, Wet bulb, etc. are present. For a full list of available parameters within the files see the 'variables' information on this record.

  • Midas-open is the open data version of the Met Office Integrated Data Archive System (MIDAS) for land surface station data (1853 – present). It contains land surface observations data from the Met Office station network that have been designated as public sector information and provided under an Open Government Licence. Midas-open is a subset of the fuller Met Office Integrated Data Archive System (MIDAS) Land and Marine Surface Stations Data (1853-current), containing only UK mainland land surface observations owned or operated by Met Office. Currently this represents approximately 95% of available daily temperature and weather observations, 83% of hourly weather data, and 13% of daily rainfall within the full MIDAS collection. A large proportion of the UK raingauge observing network is operated by other agencies so currently excluded from the Midas-open set. It does not supersede the full MIDAS collection also archived at CEDA. MIDAS Open comprises of hourly and daily weather measurements and observations of parameters relating to temperature, rainfall, sunshine, radiation, wind and weather observations such as present weather codes, cloud cover, snow etc. This dataset collection is updated annually in a delayed mode to ensure that data acquisition and quality control procedures have all been completed. Data are available from 1853 or later years, depending on the data in question. Note: not all sites operated for the entire date span; some sites were opened in later years, whilst others were closed in subsequent years. Each version of the dataset will include data for a full year upto around the 12 months previous to the year-month in the version of the dataset (e.g. v201901 included data up until the end of 2017).

  • The aim of the EUMETNET Sandbox is to bring novel observations and observations from technology trials and field campaigns to the research community to enable R&D activities. The first datasets to be made available on the Sandbox are two datasets from Personal Weather Stations (PWS) provided by Netatmo and WOW. These datasets are historical archives for a single year (2020) to support development of quality control tools and other activities carried out by EUMETNET Members and ECMWF. The Netatmo and WOW Datasets contain land surface observations, usually from weather stations located in the gardens of the public. The data are not quality controlled prior to being made available in the CEDA Archive. The datasets are stored in the format and resolution provided by the Met Office (for WOW data) and Netatmo. The WOW data are stored in a csv format with a single file per month. The files contain the data from all WOW stations within Europe. The Netatmo data are stored in tar/zip files, one file per country per month.

  • The UK daily weather observation data contain meteorological values measured on a 24 hour time scale. The measurements of sunshine duration, concrete state, snow depth, fresh snow depth, and days of snow, hail, thunder and gail were attained by observation stations operated by the Met Office across the UK operated and transmitted within DLY3208, NCM, AWSDLY and SYNOP messages. The data span from 1889 to 2018. For details of observations see the relevant sections of the MIDAS User Guide linked from this record for the various message types. This version supersedes the previous version of this dataset and a change log is available in the archive, and in the linked documentation for this record, detailing the differences between this version and the previous version. The change logs detail new, replaced and removed data.
