The radar data collected by the Landmap project consist of data from ERS (European Remote Sensing) Satellites 1 and 2 from 1995 to 1999, ENVISAT ASAR (Advanced Synthetic Aperture Radar) (available in image mode, alternating polarisation and wide swath from 2004 onwards) and ALOS PALSAR (Advanced Land Orbiting Satellite Phased Array Type L-band Synthetic Aperture Radar) data where Fine Beam Single (FBS), Fine Beam Dual (FBD) and Polarimetric (PLR) data are available from 2007 - 2009 for areas of the UK and Republic of Ireland. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK, part of which was radar data. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

Radar data collected in ice-phase clouds at the Chilbolton Observatory using radars at 3, 35 and 94 GHz during 2014-2015. The experimental setup is described in Stein et al (2015) DOI: 10.1002/2014GL062170 - see related documents section on this record. Raw pulse-to-pulse data were collected from all 3 radars, and have been post processed to common, synchronised time bins, for maximum ease of colocation. These data were produced as part of the NERC funded Exploiting multi-wavelength radar Doppler spectra to characterise the microphysics of ice hydrometeors project (grant reference: NE/K012444/1).

Data from the Synthetic Aperture Radar and Hyperspectral Airborne campaign (SHAC) run by the Natural Environment Research Council (NERC) and the British National Space Centre (BNSC). The campaign intended to provide support for industrial and academic research into earth resource and environmental monitoring. The campaign was managed by NRSC- now Infoterra. Fourteen different locations were flown in May and June 2000 in the campaign (see Fig.1), logistical constraints requiring two aircraft be used to fly the two instruments individually. The campaign involved a large number of researchers from NERC-EPFS and CEH, BAE Systems and InfoTerra on the ground collecting information vital to making best use of the airborne data: simultaneous spectral, sun photometer and GPS measurements and the installation by DERA, now QinetiQ, of corner reflectors to gain geo-coding of the E-SAR data. The outcome was previously unavailable, state-of the art, airborne data of the UK, which informed 11 research projects.

The Aberystwyth Egrett Experiment: Gravity Waves, Turbulence, Mixing and Filamentation in the Tropopause Region is a Upper Troposphere Lower Stratosphere (UTLS) Round 2 project led by Dr J. Whiteway and Dr G. Vaughan, Department of Physics, University of Wales, Aberystwyth. This dataset contains NERC MST Radar Facility at Aberystwyth, Mid-Wales.

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.

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 measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

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.

This dataset collection brings together the datasets produced from the MICROphysicS of COnvective PrEcipitation (MICROSCOPE) project, the NERC funded part of the wider COPE (COnvective Precipitation Experiment) project. COPE was led by the National Centre for Atmospheric Science (NCAS) and the UK Met Office, and involved scientists at the Universities of Leeds, Manchester and Reading, as well as international partners from the Universities of Purdue and Wyoming. As part of COPE, MICROSCOPE sought to improve predictions of severe convective rainfall by addressing the problem of the microphysics of precipitation in convective clouds. Data were collected during the project over Cornwall and Devon, UK, during July and August 2013 to study the clouds. Three research aircraft (Facility for Airborne Atmospheric Measurements (FAAM) BAe146, Met Office Civil Contingency Aircraft (MOCCA) and University of Wyoming King Air), a ground-based radar and several other ground-based instruments took measurements of exactly how the rain forms and develops. The aircraft were equipped with instruments that can distinguish between liquid and solid particles at 200 mph, for example. A major objective was to find these needles in the haystack – the first few ice crystals that form in amongst the hundreds of cloud droplets per every cubic centimetre of cloud.

This dataset collection contains radar data from the C-band Synthetic Aperture Radar (SAR) on the European Space Agency (ESA) Sentinel 1B satellite. Sentinel 1B was launched on 25th April 2016 and provides continuous all-weather, day and night imaging radar data. Three acquisition modes are available: Stripmap (SM), Interferometric Wide swath (IW), and Extra Wide swath (EW). The main operational mode is IW. The EW mode is primarily used for wide area coastal monitoring. The SM mode is only used on special request for extraordinary events such as emergency management. The SM, IW and EW modes are available in single (HH or VV) and dual (HH+HV or VV+VH) polarisation. The C-band Synthetic Aperture Radar images the Earth with enhanced frequency and revisit times obtaining full Earth coverage every two weeks. Timeliness and reliability is optimized for emergency response and operational applications with Europes’s coastal zones and shipping routes being monitored on a daily basis. The data has a wide range of scientific applications including sea-ice monitoring, imaging of forests and investigation into the carbon cycle, and the analysis of earthquakes. Data are provided by the European Space Agency (ESA) and are made available via CEDA to any registered scientific user in the UK.

The Bolton Experiment: An Experimental Test of the Use of Microwave Attenuation to improve Rainfall Estimates in Urban Areas, and hence to Enhance Flood Warning The Bolton Experiment was a NERC project with matching funds from industry which took place between 1999 and 2002.It was a collaboration between the University of Essex (Propagation and Remote Sensing group, the University of Salford (Telford Research Institute), and the Rutherford Appleton Laboratory (Radiocommunications Research Unit) and the industrial partners North West Water Plc and Norweb Communications (both companies of United Utilities), the UK Meteorological Office, The Environment Agency and Crown Castle International. The purpose of the study is to test the proposal developed at Essex, in conjunction with RAL, that the difference in attenuation at two microwave frequencies along a given path provides an accurate estimate of path-integrated rainfall rate, and to investigate its application to hydrological studies of urban catchments. The catchment selected for study is the Bolton catchment, in which the town is largely surrounded by hills, and the River Croal is carried in culverts in the town centre. Four microwave links will be set up, three of them dual frequency and one single frequency. In addition to data from microwave links and radar, there will also be data available from a number of telemetered tipping bucket raingauges. The dataset contains microwave, raingauge and radar data. It also contains data analysis to extract information from the link attenuation data on path-averaged rainfall rate, and comparison with the results with those obtained from the raingauges and the radar. The dataset is now public.
