    Ksat data and derived services
    KSAT data and derived services

    • MODIS data, increasing interest

      • snow cover mapping for hydropower production planning,

      • flood monitoring.

      •  KSAT provides MODIS data and derived products for snow mapping during the melting season as part of an EU FRP project Envisnow.

    • Development and provision of marine earth observation services, new oceanographic information services:

      • Oceanographic information, wind and waves, is needed to provide reliable services.

      • Growing need for wind and wave information to serve the met. communities in Europe.

    • Potential new services

      • ”Global” and fast access to (MODIS) optical data for European and Global users

      • MODIS polar winds

      • Coriolis/WindSat service

    Coriolis wind information service
    Coriolis wind information service

    • Spaceborne wind measurements

      • ERS scatterometer data less availability

      • Japanese Adeos-2 satellite failed

      • Envisat does not operate a scatterometer.

    •  Operational institutional users in Europe such as met. institutes in a more difficult position with respect to service and information availability.

    • Emerging opportunity recognition

      • The KSAT capabilities to provide near real-time services

      • Coriolis Windsat knowledge and the data access via Svalbard,

      •  1) Mission found an increasing interest among European met. institutes.

      •  2) KSAT evaluated how a WindSat processing chain at Svalbard/Tromsø could meet European needs for fast access to wind speed and direction information.

      • A Coriolis wind service can and will complement KSAT Envisat ASAR NRT wind information service

    Proposed coriolis mission and service scenario
    Proposed Coriolis mission and service scenario

    • Downlink regional mission data to Svalbard and a second KSAT ground station (Tromsø or Grimstad). 4-6 passes per day.

    • Downlink on-board recorded global data to Svalbard

    • Supplementary access based on downlink of data to US facilities

    • Additional stations further South in Europe if required by the users

    • Raw data distributed via fibre link to Tromsø.

    • Near real-time distribution of derived wind information via land lines to institutional European users

    Black line = raw data

    Red line = derived information

    Direct read out modis data
    Direct read out MODIS data

    • KSAT operational reception of MODIS data

      • Direct downlink Tromsø, Svalbard and Grimstad

      • Global dump Svalbard under NOAA/NASA contract

    • Future MODIS data type continuity, and KSAT operational ambitions for ”one-stop-shop”

      • Expand current capabilities and services (web-based technology)

      • Delivery of (Level 1B) data to users/VA companies

      • Utilisation of MODIS (-type) data for operational services. 1. Information reliability improvement optical+SAR data e.g algae vs oil spills2. New services based on MODIS-type (Polar winds, snow cover mapping)

    Conclusions the next step
    Conclusions – The next step

    • Coriolis mission and the capability is known

    • Coriolis wind information will be a supplement to European institutional users/VA

    • Coriolis wind information may be included in KSAT wind service

    • Develop services based on the use of Svalbard and Troll and ESTABLISH A POLAR WORKING GROUP FOR DB APPLICATIONS
