  • The Contribution of Global Ocean Observation of Continuity of HY-2
    CGMS-XXXVI-CNSA-WP-04 Prepared by CNSA Agenda Item: III/3&4 The contribution of global ocean observation of continuity of HY-2 satellite HY-2 satellite, an ocean dynamic environment observation satellite, mainly ` objective is monitoring and detecting the parameters of ocean dynamic environment. These parameters include sea surface wind fields, sea surface height, wave height, gravity field, ocean circulation and sea surface temperature etc. The contribution of global ocean observation of continuity of HY-2 satellite 1. Introduction HY-2 satellite scatterometer provides sea surface wind fields, which can offset the observation gap of the plan of global scatterometer. At the same time, HY-2 satellite altimeter provides sea surface height, significant wave height, sea surface wind speed and polar ice sheet elevation, which can offset the observation gap of the plan of global altimeter around 2012, and can offset the observation gap of JASON-1&2 at polar area. More details as follows. 2. Observation of sea surface wind fields The analysis accuracy of wind field for ocean-atmosphere can improve 10-20% by using the satellite scatterometer data, by which can improve greatly the quality of initial wind field of numerical atmospheric forecast model in coastal ocean. Satellite scatterometer data has play important role on study of large-scale ocean phenomenon, such as sea-air interactions, ocean circulation, EI Nino etc. The figure 1 shows that QuikSCAT scatterometer has operational application in 1999, but it has not the following plan. ERS-2 scatterometer mission has transferred to METOP ASCAT in 2006. GCOM-B1 will launch in 2008, one of its payloads is an ocean vector wind measurement (OVWM) instruments, and it also called AlphaScat.

  • On the Use of Scatterometer Winds in Nwp
    ON THE USE OF SCATTEROMETER WINDS IN NWP Ad Stoffelen KNMI, de Bilt, the Netherlands, Email: [email protected] Lars Isaksen, Didier le Meur ECMWF, Reading, UK ABSTRACT Over the last years the processing of ERS scatterometer winds has been refined. Subsequently, High Resolution Limited Area Model, HIRLAM, and ECMWF model data assimilation experiments have been carried out to assess the impact of one scatterometer, ERS-1 and of two scatterometers, ERS-1 and ERS-2, on the analyses and forecasts. We found that scatterometer winds have a clear and beneficial impact in the data assimilation cycle and on the forecasts. Furthermore, ECMWF has shown that ERS scatterometer data improve the prediction of tropical cyclones in 4Dvar, where unprecedented skillful medium-range forecasts result of potential large social-economic value. Nevertheless, scatterometer winds contain much sub-synoptic scale information where the smallest scales resolved are difficult to assimilate into a Numerical Weather Prediction, NWP, model. This is mainly due to the otherwise general sparsity of the observing system over the ocean. In line with this it is found that scatterometer data coverage is very important for obtaining a large impact. In that respect future scatterometer systems such as SeaWinds on QuikSCAT and ADEOS- II, and ASCAT on EPS are promising. 1. INTRODUCTION After the launch of ERS-1 much improvement has been made in the interpretation of scatterometer backscatter measurements and a good quality wind product has emerged (Stoffelen and Anderson, 1997a, 1997b and 1997c). The consistency of the scatterometer winds over the swath makes them particularly useful for nowcasting purposes and several examples of the usefulness of the direct visual presentation of scatterometer winds to a meteorologist can be given.

  • Sentinel-1A Launch
    SENTINEL-1A LAUNCH Arianespace’s seventh Soyuz launch from the Guiana Space Center will orbit Sentinel-1A, the first satellite in Europe’s Earth observation program, Copernicus. The European Space Agency (ESA) chose Thales Alenia Space to design, develop and build the satellite, as well as perform related tests. Copernicus is the new name for the European program previously known as GMES (Global Monitoring for Environment and Security), and is the European Commission’s second major space program, following Galileo. Copernicus is designed to give Europe continuous, independent and reliable access to Earth observation data. With the Soyuz, Ariane 5 and Vega launchers at the Guiana Space Center (CSG), Arianespace is the only launch services provider in the world capable of launching all types of payloads into all orbits, from the smallest to the largest geostationary satellites, from satellite clusters for constellations to cargo missions for the International Space Station (ISS). Arianespace sets the launch services standard for all operators, whether commercial or governmental, and guarantees access to space for scientific missions. Sentinel-1A is the 50th satellite with an Earth observation payload to be launched by Arianespace. Arianespace has seven more Earth observation missions in its order book, including four commercial missions (signed in 2013 and 2014). The Copernicus program is designed to give Europe complete independence in the acquisition and management of environmental data concerning our planet. ESA’s Sentinel programs comprise five satellite families: Sentinel-1, to provide continuity for radar data from ERS and Envisat. Sentinel-2 and Sentinel-3, dedicated to the observation of the Earth and its oceans.
