Modelling for Operational ForecastingModelling for Operational ForecastingThe TUNAMI N2 model is customized for Indian Ocean region
This model had been extensively validated using the December 26 2004 Tsunami observations
For operational forecast A large database of open ocean propagations scenarios For epicenters separated by 100 km all along two Tsunamigenic zones Scenarios for different magnitudes (6.5, 7.0, 7.5, 8.0, 8.5, 9.0 & 9.5) and depths (10, 20, 40, 60, 80 & 100 km)
Travel timesSurge heightsDirectivity maps
Each simulation covers the entire Indian Ocean domain with 15 hours simulation time and a time step of 5 seconds. Out put profiles are generated at 30 m bathymetry for about 1800 coastal fore cast points (CFPs) covering the entire Indian ocean rim countries including Tide Gauge & BPR locations

scenarios simulated for 5 historical Earthquakes using TUNAMI N2 model and the predicted inundation areas have been overlaid on cadastral level maps of 1:5000 scale.
Coastal Bathymetry: Maps of Special Order are required (Accuracy 0.5 M)
Coastal Topography: Contour Intervals of 0.5 M at 1:25, 000 Scale are required

New Initiatives• INCOIS has become the DAC of the
OceanSITES Programme on Global Network of Time-series stations– Developed datasets (daily) along with
meta-data of moored buoy observations complaint to OceanSITES program
– The moored buoy and current meter mooring data sets are being prepared in netCDF as per the OceanSITES Standards
• Ocean Science Interoperability Experiment of OGC• Developed GML Schema for providing metadata to
NSDI/NRDMS/DST
OGC Ocean Science Interoperability Experiment - II
Major tasks include:
Publishing of trajectories, vertical and horizontal profiles observationsPublishing and performance of long time series observationsNetCDF / OpenDAP and SOS Chaining Gridded data and stations.Serving of observation offerings for complex systems, For example,
observations systems containing other systems, platforms with multiple sensors),
Serving of event based observations. For example, all tsunami sensors within +/- 12 hrs of a given tsunami.
Publishing of Sensor Observation Services……
Summary• Developed integrated in-situ data and
information system• Ocean remote sensing database is being
generated• Potentials of GIS Technology along with ICT
are effectively utilized for providing Ocean Data, Information and Advisory Services
• Demonstrated the capability of Open source Map Server for providing Oceanographic data with visualization capabilities
Way forward
• Ocean remote sensing database management
• Integration of in-situ and remote sensing data sets
• Development of Digital Indian Ocean• Networking of Marine Data Centres
