SPECS will undertake research and dissemination activities to deliver a new generation of European climate forecast systems, with improved forecast quality and efficient regionalisation tools to produce reliable, local climate information over land at seasonal-to-decadal time scales, and provide an enhanced communication protocol and services to satisfy the climate information needs of a wide range of public and private stakeholders. A core set of common experiments has been defined, to which most forecast systems will contribute. Another set of coordinated experiments, tier 1, includes the experiments that one or more forecast systems are planning to run. A standard seasonal experimental set up will consist of ten-member ensembles, with two start dates per year (first of May and November) over the 1981-2012 period and seven-month forecast length. The standard decadal experimental set up consists in five-member ensembles, starting on the first of November (or some time close to that date) of the years 1960, 1963, 1965, 1968, 1970, 1973, 1975, 1978, 1980, 1983, 1985, 1988, 1990, 1993, 1995, 1998, 2000, 2003, 2005, 2008, 2010, 2013, with a five-year forecast length. A description of the main experiments, with the minimum contribution in terms of start dates, forecast length and ensemble size follows: 1 - Assessment of the impact of soil-moisture initial conditions (seasonal): contributing EC-Earth, IFS/NEMO (ECMWF), CNRM-CM5 (MeteoF), UM, MPI-ESM (MPG); 2 - Assessment of the impact of sea-ice initialization (interannual); contributing EC-Earth (IC3), IPSL-CM5, CNRM-CM5 (MeteoF), UM, MPI-ESM (MPG) 3 - Assessment of impact of increased horizontal resolution (seasonal and decadal); contributing CNRM-CM5 (CERFACS, decadal; MeteoF, seasonal), EC-Earth (IC3, seasonal; KNMI and SMHI, decadal), MPI-ESM (MPG, seasonal and decadal), IPSL-CM5 (decadal), UM (seasonal and decadal); 4 - Assessment of impact of an improved stratosphere (seasonal and decadal) including interannually-varying ozone; contributing EC-Earth (KNMI seasonal with ozone; SMHI decadal), IFS/NEMO (ECMWF, seasonal), CNRM-CM5 (MeteoF, seasonal), UM (seasonal, decadal); 5 - Assessment of impact of additional start dates (decadal); contributing EC-Earth (KNMI, SMHI), MPI-ESM (MPG), IPSL-CM5. SPECS research has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under SPECS project (grant agreement n° 308378).

Tropospheric ORganic CHemistry Experiment (TORCH) was a Natural Environment Research Council (NERC) Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00145. Duration 2002 - 2005) led by A. Lewis, University of York. TORCH 1 took place in July and August 2003 at Writtle College, near Chelmsford, Essex. This dataset contains ECMWF trajectories

This CD-ROM is produced by the European Space Agency (ESA) and contains land surface temperature demonstration products as estimated from the Advanced Very High Resolution Radiometer (AVHRR) sensor onboard the National Oceanic and Atmospheric Administration (NOAA) series of polar orbiters. The data used are from the full resolution (1 km) composites (decade) data set processed in the framework of the "1 km AVHRR Global Land Data Set" collaborative project of the United States Geological Survey (USGS) EROS Data Centre (EDC), NOAA, NASA, ESA under the guidance of IGBP and CEOS. This CD-ROM contains excerpts from the full resolution land surface temperature (1 km pixel) data set over Europe, as well as so called world monthly "climatic values" (0.5 degree x 0.5 degree grid). The full processed data set runs from July 1992 to June 1993. This dataset contains climatic land Surface temperatures measurements over a month and a square half degree grid.

This dataset contains daily monthly average T159 spherical harmonics gridded, potential temperature level, analysis timestep data 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.

Tropospheric ORganic CHemistry Experiment (TORCH) was a Natural Environment Research Council (NERC) Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00145. Duration 2002 - 2005) led by A. Lewis, University of York. TORCH 2 took place in April and May 2004 at Weybourne Atmospheric Observatory, on the north Norfolk coast. This dataset contains NMHC, O-VOC and DMS measurement by dual channel PTV-GC-FID.

The Cloud and Water Vapour Experiment (CWAVE) was a measurement campaign at the CCLRC-Chilbolton Observatory; it was supporting associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition, the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office. This dataset contains Met Office Microwave radiometer (MP series) temperature, water vapour and liquid profiles at Chilbolton Facility for Atmospheric and Radio Research (CFARR)

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 ozone and meteorology measurements.

The Met Office deployed a Vaisala Radian LAP3000 915 MHz wind profiler at the Met Office's meteorological station on the South Uist range, Hebredies, from January 2003 to July 2004. This deployment was ahead of the installation of the Met Office's 64 MHz Stratosphere-Troposphere (ST) radar at the same site and provided a period of colocated measurements from the two instruments from May to July 2004. At the time the Met Office's 915 Mhz wind profiler was an integral part of the Met Office's UK "Operational Upper Air Network", providing high resolution wind information from just above the surface (around 300m) up to a maximum of 8 km, depending on the atmospheric conditions. The South Uist site is located at 57.353 N, 7.375 W and a height of 4 m above mean sea-level. The site has a WMO id of 03019. The instrument's hight resolution is 60/200 m depending on the operational mode. It has a beam angle of 15.0 degrees and is operated with an averaging period of 30 minutes. This instrument had been previously deployed at the Capel Dewi site near Aberystwyth and was subsequently deployed to its present location on the Isle of Man in 2005. This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 915MHz wind profiler located at South Uist.

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 NO, NO2, CH4, O3, HF, HCl, ClONO2, HNO3, CFC-11 and CFC-12 from the BRUKER IFS 120M FTIR spectrometer.
