  • 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 These data are the Met Office's 'old' Land Surface Observation data and have been superseded by the MIDAS dataset collection.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

  • The Campbell Scientific PWS100 present weather sensor deployed at the Chilbolton Observatory, Hampshire, detects and classifies precipitation by observing the scattering of a laser beam 20 degrees off the forward direction in the horizontal and vertical planes. The detected signals depend on the size, shape, optical properties, concentration and velocity of the particles. The instrument is mounted approximately 10m above ground on the roof of a cabin at the Chilbolton Observatory site. It is operated continuously. Data include: counts as a function of size of hydrometeors in 300 bins from 0.1 to 30.0 mm, the number of hydrometeors in 9 type categories. visibility, air temperature, relative humidity, rainfall rate, rainfall accumulation, average hydrometeor velocity, average hydrometeor size and reports the World Meteorological Organisation (WMO) present weather code for the site. Data are archived as netCDF files.

  • The WATCH forcing data (WFD) is a twentieth century meteorological forcing dataset for land surface and hydrological models. It consists of three/six-hourly states of the weather for global half-degree land grid points. It was generated as part of the EU FP 6 project "WATCH" (WATer and global CHange") which ran from 2007-2011. The data was generated in 2 tranches with slightly different methodology: 1901-1957 and 1958-2001, but generally the dataset can be considered as continuous. More details regarding the generation process can be found in the associated WATCH technical report and paper in J. Hydrometeorology. To understand how the data grid is formed it is necessary to read the attached WFD-land-long-lat-z files either in NetCDF or dat formats. The data covers land points only and excludes the Antarctica. Rainf or rainfall rate is the rainfall rate based on the Global Precipitation Climatology Centre (GPCC) bias corrected, undercatch corrected measured in kg/m2/s at 3 hourly resolution averaged over the next 3 hours and at 0.5 x 0.5 degrees spatial resolution. Please note that there is also a WFD Rainf CRU bias corrected dataset, but as the GPCC dataset is the preferred dataset only this rainfall dataset is available from the EIDC. These rainfall datasets contain rainfall data only and need to be combined with the respective WFD snowfall datasets to obtain precipitation data.

  • The UK Colonial Registers and Royal Navy Logbooks (CORRAL) project uses late 18th to early 20th century archive material to enhance the global coverage of daily to sub-daily weather observations by digitising Royal Navy ship's logbooks (from ships of voyages of scientific discovery and those in the service of the Hydrographic Survey) and coastal and island records contained in UK Colonial documents. This provides meteorological recordings from marine sites back to the 18th Century. These data are public. These records are held at The National Archive, Kew. The ADM section includes records of the Admiralty, Naval Forces, Royal Marines, Coastguard, and related bodies, concerning all aspects of the organisation and operation of the Royal Navy and associated naval forces, over the period 1205-1998 (more details are available in the National Archives catalogue entry). The CORRAL project deals with the following series: ADM51: Admiralty: Captains' Logs, 1669-1853 ADM53: Admiralty: and Ministry of Defence, Navy Department: Ships' Logs 1799-1985 [Excluding Flying Squadron] ADM53 -- Flying Squadron: Admiralty: and Ministry of Defence, Navy Department: Ships' Logs 1869-1872 ADM55: Admiralty: Supplementary Logs and Journals of Ships on Exploration, 1757-1861; 1904, including logs from the voyages of James Cook.

  • The Airborne Antarctic Ozone Experiment (AAOE) aimed to study chemical composition and physical parameters in the Antarctic during the development of the Antarctic Ozone Hole in August and September 1987. The data is primarily that collected onboard the NASA ER-2 and DC-8 aircraft, along with ozonesonde data collected at four Antarctic stations: Halley Bay, McMurdo, Palmer Station, and the South Pole. The experiment tested the chemical and dynamical theories of the ozone hole using the aircraft data in theoretical computer models of the chemistry and dynamics of the stratosphere. The data include atmospheric composition, meteorological parameters, aerosol data and cloud data. The NASA ER-2 is a high altitude research aircraft that sampled air at those altitudes where the ozone hole was at its most intense, with data gathered on the air mass within the confines of the hole itself. The ER-2 collected information on three-dimensional winds, pressure, temperature, temperature profiles +/- 1 km from flight level, chlorine monoxide, bromine monoxide, ozone, nitric oxide, reactive nitrogen, total water, nitrous oxide, whole air sampling, condensation nuclei, aerosol size distribution and composition, and cloud particle images and sizes. The DC-8 aircraft flew at the lowermost extremities of the hole and deployed a combination of remote sounding of the overlying atmosphere with some in situ sampling. Vertical distributions of ozone and aerosols above the cruising altitude of the aircraft and within the hole were mapped. The DC-8 collected ozone and aerosol profiles overhead by LIDAR; and measured ozone, bromine oxide, OClO, nitrogen dioxide, nitric acid, and hydrogen chloride. In situ methods yielded ozone, total water, and whole air sampling.

  • The Coupled Ocean Atmosphere and European Climate (COAPEC) is a NERC thematic programme designed to examine the variability of the Earth's climate. The goal of COAPEC is to determine the impact on climate, especially European climate, of the coupling between the Atlantic Ocean and the atmosphere. The British Atmospheric Data Centre (BADC) is the primary distribution data centre for COAPEC. This dataset contains heat flux monthly data from the Southampton Oceanographic Centre (SOC).

  • The University of Salford automatic weather station data describe observations made every 5 seconds with the data stored every one minute and 10 minutes at Faccombe wind turbine field site, Hampshire, form the 3rd of June 2005 until the 26th of August 2005.. The dataset contains measurements of the following parameters: Average air temperature Average dew point (measured from 11:54 BST 22nd June 2005) Average relative humidity Average net radiation Average wind speed Maximum wind speed Time of maximum wind speed Total rainfall Average pressure Average wind direction Minimum wind direction Maximum wind direction Average battery Two jpeg images files have been produced from the AWS data for each day from 3rd June 2005 (start of CSIP field project) until 26th August 2005 (end of CSIP field project). There are two image files, the first image file listed below contains plots of the windspeed, pressure and rainfall with time for a particular day. The second image file contains air temperature, relative humidity and net radiation plots with time for a particular day. The weather station consists of a Campbell Scientific 2 m tripod with a CR10X datalogger. Weather station sensors include a MP100A temperature and relative humidity probe, a A100L2 low power anemometer, a W200P potentiometer wind vane, a NR-Lite Net Radiometer, a RPT410F barometric pressure sensor and a ARG100 Tipping bucket rain gauge.

  • Data were collected from the 4th of April 2002 to the present by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire. The dataset contains measurement and display of the full Doppler spectrum, and the moments Z, v and w of air.

  • 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.

  • Data were collected from the 30th of March 1999 to the 30th of March 2011 by the CAMRa (Chilbolton Advanced Meteorological Radar) at Chilbolton Observatory, Hampshire. The dataset contains measurements of radial component of wind velocity, radar frequency, differential phase shift and unfolded Doppler velocity. Plots are also available of differential phase shift, Doppler velocity, radar reflectivity factor, and linear depolarisation ratio.
