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 advanced along-track scanning radiometer measurements.

Abstract This computation involved: DETAILS NEEDED - COMPUTATION CREATED FOR SATELLITE COMPOSITE. deployed on Envisat. In March 2002, the European Space Agency launched Envisat, an advanced polar-orbiting Earth observation satellite which provides measurements of the atmosphere, ocean, land, and ice. The Envisat satellite has a payload of 10 instruments that will ensure the continuity of the data measurements of the ESA ERS satellites. Envisat data supports earth science research and allows monitoring of the evolution of environmental and climatic changes. <div property="cedacat:introduction"> <div class="introduction">Introduction</div> <p>Envisat flies in a sun-synchronous polar orbit of about 800-km altitude. The repeat cycle of the reference orbit is 35 days, and for most sensors, being wide swath, it provides a complete coverage of the globe within one to three days. The exceptions are the profiling instruments MWR and RA-2 which do not provide real global coverage, but span a tight grid of measurements over the globe. This grid is the same 35-day repeat pattern which has been well established by ERS-1 and ERS-2.</p> <p> In order to ensure an efficient and optimum use of the system resources and to guarantee the achievement of the mission objectives Envisat reference mission operation profiles are established and used for mission and system analyses to define the instrument operational strategies, the command and control, and the data transmission, processing and distribution scenarios. </p> <p> Mission and operation requirements <br /> </p><ul> <li>Sun-synchronous polar orbit (SSO): Nominal reference orbit of mean altitude 800 km, 35 days repeat cycle, 10:00 AM mean local solar time (MLST) descending node, 98.55 deg. inclination. </li><li>The orbit is controlled to a maximum deviation of +/- 1 km from ground track and +/- 5 minutes on the equator crossing MLST. </li><li>Recording of payload data over each orbit for low bit rate (4.6 Mps) on tape recorders or solid state recorder (SSR). </li><li>High rate data (ASAR and MERIS) to be accessible by direct telemetry or recording on SSR. </li></ul> Payload: <ul> <li>ASAR - Advanced Synthetic Aperture Radar </li><li>MERIS - MEdium-spectral Resolution, Imaging Spectrometer </li><li>AATSR - Advanced Along Track Scanning Radiometer </li><li>RA-2 - Radar Altimeter 2 </li><li>MWR - MicroWave Radiometer </li><li>GOMOS - Global Ozone Monitoring by Occultation of Stars </li><li>MIPAS - Michelson Interferometer for Passive Atmospheric Sounding </li><li>SCIAMACHY - Scanning Imaging Absorption Spectrometer for Atmospheric Chartography </li><li>DORIS - Doppler Orbitography and Radio-positioning Integrated by Satellite instrument </li><li>LRR - Laser Retro-Reflector </li></ul> <p /> </div>
