  1. NordKyst-800mThe Norwegian Coastal ModelBjørn ÅdlandsvikInstitute of Marine Research Opnet, Geilo, 27-28 May 2010

  2. What • NorKyst-800m is a model setup under development with 800 m resolution covering the entire Norwegian coast • Flexible setup: run the whole or subdomains • Present partners: IMR, met.no, NIVA • Open access: Model grid and forcing available to everybody, pilot setup for the Regional Ocean Modeling System (ROMS). Other partners and other models are welcome.

  3. Why • Increasing interest in coast and fjord areas • aquaculture, transport, tourism, ... • Need knowledge for coastal management • Operational use • Shipping accidents, oil spills, harmful algae blooms • Additional products • Transport models: pollution, salmon lice, eggs and larvae of coastal cod • Provide input to higher resolution fjord models

  4. How • Cross-institutional collaboration • Presently IMR, met.no, NIVA • Initiative and project leader: • Lars Asplin, IMR

  5. What • Topography, land mask – Jon Albretsen, IMR • Cartesian grid in polar stereographic plane • 2602 x 902 grid cells • Resolution approx. 800 m • Topography from GEBCO-08 • Land contours from Norge digitalt

  6. Bottom matrix

  7. Bottom matrix around Askøy

  8. What • Topography, land mask – Jon Albretsen, IMR • Tidal forcing – Ann Kristin Sperrevik, met.no • 8 constituents • K2 S2 M2 N2 K1 P1 O1 Q1 • Data from TPXO, Oregon State University

  9. What • Topography, land mask – Jon Albretsen, IMR • Tidal forcing – Ann Kristin Sperrevik, met.no • River forcing – André Stålstrøm, NIVA • 247 rivers • Data from NVE

  10. River positions

  11. Version zero • Interpolation from met.no operational 4 km to 800 m grid, no separate model run • Early start for developing diagnostics, validation tools and other products around the model • No extra cost: interpolation needed anyway to provide initial and boundary conditions

  12. Version one • Atmospheric, river and ocean boundary forcing available • Setup for Regional Ocean Model System (ROMS)‏ • Test runs

  13. Further work • Operational use at met.no • Distribution of operational results and forcing to partners • Flexible ROMS setups at IMR, NIVA • Validation • Distribution of results and added products to users
