KSAT ground segment & services
Svalbard = The polar meteorological satellite facility (IPO, Eumetsat)
Troll, Future meteorological site in Antarctica
SAR based services– Oil Spill detection– Ship detection for maritime security– Ice applications/data and services– Wind (speed, direction) information – Land applications
- Snow & Flood mapping and monitoring
Other relevant/optical data and services– Terra, Aqua MODIS data– Coriolis WINDSAT data– TIROS-N NOAA/AVHRR data

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
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
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
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
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
