  • Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Infra-Red Radiometer from 10th of May 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements for both sky and surface emitted infrared radiation, from 4.5 to 42 µm.

  • Data were collected by Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements of rainfall accumulation as measured by multiple instruments.

  • Data were collected from the 31st of March 2004 to the 29th of March 2011 by the Copernicus Doppler cloud radar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

  • Data from the NIMROD system data describe rain-rate observations in Northern Europe taken by NIMROD, which is a very short range forecasting system used by the Met Office. Composite European data are available from April 2002 until present, collected by a network of rain radars at northern European stations. Radar images from the 15 C-band (5.3 cm wavelength) radars around Europe at 5 km resolution, are received by the Nimrod system at 15 minute intervals. Data products are available since April 2002, whilst image products are available from February 2003. Each file has been compressed and then stored within daily tar archive files. The precipitation rate analysis uses processed radar and satellite data, together with surface reports and Numerical Weather Prediction (NWP) fields. Europe has a network of 15 C-band rainfall radars and data form these are processed by the Met Office NIMROD system. The data files contain integer precipitation rates in unit of (mm/hr)*32. Each value is between 0 and 32767. In practice it is rare to see a value in excess of 4096 i.e. 128 mm/hr CEDA are not able to fulfil requests for data that are missing from this archive. The data may be available at a cost by contacting the Met Office directly with required dates. It is worth contacting CEDA first to check if the reason for the gap is already identified as being due to the data not existing at all.

  • The International Satellite Land Surface Climatology Project, Initiative II (ISLSCP II) is a follow on project from The International Satellite Land Surface Climatology Project (ISLSCP). ISLSCP II had the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP). This dataset contains: *Sea Ice extent *Sea surface temperature *Snow cover The data are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public.

  • A Vaisala Radian LAP3000 1290 MHz wind profiler has been permanently located at the Met Office's site at the Wattisham airfield near Ipswich, Suffolk, and has been operational since February 1999. This was one of two such profilers deployed in the UK at that time as part of the Met Office's UK "Operational Upper Air Network." Operating at 1290 Mhz, Dunkeswell, like the other sites, is configured to operate in two modes. The low mode provides high resolution wind information from 239m to 2060 m with a heigh resolution of 102m; while the high mode, with 205 m resolution can sound from 347 m up to 8239 m depending on appropriate atmospheric conditions. The site is located at 52.70 N, 0.058 E and a height of 87 m above mean sea-level and has a WMO id of 03591. It had a beam angle of 15.5 degrees and is operated with an averaging period of 30 minutes. This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 1290MHz wind profiler located at Wattisham.

  • The Met Office's 64 MHz ST (stratosphere-troposphere) wind profiler was installed at the Met Office South Uist range meteorological station, Hebrides, in May 2003. The radar complements the MST radar located near Abersywyth, providing greater vertical coverage than the other wind profiling radars in the Met Office's UK "Operational Upper Air Network." Operating at 64 Mhz, the South Uist 64 Mhz radar runs typically sounds from 1 to 13 km with a heigh resolution of either 150 or 400m, depending on the mode of operation. The site is located at 57.353 N, 7.375 W and at a height of 4 m above mean sea-level and has a WMO id of 03019. It had a beam angle of 15.0 degrees and is operated with an averaging period of 30 minutes. This dataset contains vertical wind profiles from the 64MHz wind profiler located at Camborne.

The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP). This dataset contains: *Cloud measurements *Ozone *Radiation The data are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public.

  • Data were collected by Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 15th of March 2002 to the present at Sparsholt College, Hampshire. The dataset contains measurements of rainfall accumulation as measured by RAL Rapid Response Drop Counting rain gauges.

  • HIRDLS was a mid-infrared limb-scanning radiometer (21 channels from 6.12 to 17.76 µm and provided sounding observations to observe the lower stratosphere with improved sensitivity and accuracy. HIRDLS was carried on the Aura mission, part of the A-train procession of polar orbiting satellites forming part of NASA's Earth Observing System (EOS). This dataset contains level 2 version 5.00 data of the global distributions of temperature, clouds, aerosols, and 10 trace species O3, H2O, CH4, N2O, NO2, HNO3, N2O5, CFC11, CFC12, and ClONO2 in the stratosphere and upper troposphere at high vertical and horizontal resolution in the Earth's atmosphere between about 8 and 100 km, from the High Resolution Dynamics Limb Sounder (HIRDLS) instrument.
