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
