  • The dataset contains time series observations of turbulent surface-atmosphere exchanges of sensible heat (H) and momentum (τ) measured at an area of ancient broadleaved deciduous forest in Oxfordshire, UK (Wytham Woods). Turbulent flux densities were monitored from the top of a forest tower using the micrometeorological eddy covariance (EC) technique between 2014-06-13 13:00 and 2016-01-04 22:00. The dataset includes ancillary weather and soil physics observations, as well as variables describing atmospheric turbulence and the quality of the turbulent flux observations. Data were collected by staff from the Centre for Ecology & Hydrology, Wallingford. Full details about this dataset can be found at https://doi.org/10.5285/9b9ae2fe-e545-4209-b35f-e2ef6231dfe6

  • The World Climate Research Program (WCRP) Coupled Model Intercomparison Project, Phase 6 (CMIP6) data from the Met Office Hadley Centre (MOHC) UKESM1-0-LL model output for the "update of RCP2.6 based on SSP1" (ssp126) experiment. These are available at the following frequencies: AERday, AERmon, AERmonZ, Amon, CFmon, Eday, EdayZ, Emon, EmonZ, LImon, Lmon, Oday, Omon, SIday, SImon and day. The runs included the ensemble members: r1i1p1f2, r2i1p1f2, r3i1p1f2, r4i1p1f2 and r8i1p1f2. CMIP6 was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the WCRP and provided input for the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report (AR6).

  • The HADRT2.1 data are global monthly fields of radiosonde temperature anomalies at standard pressure levels on a 5 degree latitude by 10 degree longitude grid from 1958 to July 2004. Anomalies are calculated with respect to 1971-1990 climatology. Anomalies are available for 9 standard levels (850, 700, 500, 300, 200, 150, 100, 50, 30hPa) as well as tropospheric (850 - 300hPa) and stratospheric (150 - 30hPa) averages. The data are degree Celsius anomalies from 1970-1990 means. Anomalies are calculated for each of about 200 sonde stations worldwide and grid values derived from these. HADRT2.1 is as HadRT2.0 but with bias corrections made to many station time series world-wide. The adjustments were calculated by reference to MSU data products, but only for known changes in instrumental or operational procedures for the period post 1979. No data are available for the 30hPa level in this version. This dataset has been superseded by the HadAT dataset also available from CEDA.

  • The University of Leeds radiosonde data contain measurements collected by a radiosonde at Archern and Hornisgrinde, Germany from the 19th of April 2007 to the 30th of August 2007. The dataset contains measurements of air temperature, air pressure, wind speed and wind direction, and relative humidity. The dataset contains the following measurements: Scaled logarithmic pressure (4096 * ln P) Air temperature (K Relative humidity (percent) Northward wind (m s-1) Eastward_wind (m s-1) Altitude (m) Air pressure (hPa) Dew point temperature (K) Humidity mixing ratio (g/kg) Wind from direction (degree) Wind speed (m s-1) Sonde azimuth (degree) Sonde distance (m) Longitude (degree_east) Latitude (degree_north)

  • WCRP CMIP5: Meteorological Research Institute of KMA MRI-CGCM3 model output for the RCP2.6 (rcp26) experiment. These data cover the following realms: aerosol, atmos, land, landIce, ocean and seaIce; at the following frequencies: 3hr, day, fx and mon. The runs included the ensemble members: r0i0p0 and r1i1p1. The WCRP Coupled Model Intercomparison Project, Phase 5 (CMIP5), was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the World Climate Research Program (WCRP) and provided input for the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5).

  • The African Easterly Jet (AEJ) is part of a climatic system which is of critical importance to African and global weather and climate, but is poorly observed and not well represented in model analyses. For the JET2000 project the Met Office Met Research flight (MRF) aircraft performed four flights, involving transects along and across the jet and the baroclinic zone, to make observations of unprecedented resolution for this part of the world. 110 dropsondes were dropped along the fight path. The data includes detailed synoptic observations of the basic state over mainland West Africa, and detailed synoptic observations of the African Easterly Waves (AEW) over mainland tropical West Africa.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains vertical column measurements of NO2, O4, H2O and O3.

  • Cloud base and backscatter data from the Met Office's Vaisala Ct25k ceilometer located at St Helena, British Overseas Territory. The Met Office's laser cloud base recorders network (LCBRs), or ceilometers, returns a range of products for use in forecasting and hazard detection. The backscatter profiles can allow detection of aerosol species such as volcanic ash where suitable instrumentation is deployed.

  • WCRP CMIP5: Canadian Centre for Climate Modelling and Analysis (CCCma) CanESM2 model output for the 1 percent per year CO2 (1pctCO2) experiment. These data cover the following realms: aerosol, atmos, land, landIce, ocean, ocnBgchem and seaIce; at the following frequencies: day, fx, mon and yr. The runs included the ensemble members: r0i0p0 and r1i1p1. The WCRP Coupled Model Intercomparison Project, Phase 5 (CMIP5), was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the World Climate Research Program (WCRP) and provided input for the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5).

  • The World Climate Research Program (WCRP) Coupled Model Intercomparison Project, Phase 6 (CMIP6) data from the the CNRM-CERFACS team CNRM-ESM2-1 model output for the "update of RCP8.5 based on SSP5" (ssp585) experiment. These are available at the following frequencies: 3hr, 6hrLev, 6hrPlevPt, AERmon, AERmonZ, Amon, E1hr, E3hr, Eday, Emon, LImon, Lmon, Oday, Omon and day.
