Ichthyop Meeting of Friday, June 13, 2008

• Thomas Shay
• Trond Kristiansen
• Nate Putman
• Chris Calloway

1. v1.0.0 of mihihycom tagged
2. Set to discuss variable transform functions
3. Vertical coordinate transform
4. HYCOM Vertical coordinates
5. ROMS vertical discretization
6. Need bathymetry grid
   • E-topo-5 database?
7. Is HYCOM "Depth" the top of layer?
8. What is HYCOM sea surface height reference? (geoid? which?)
9. Create separate module for vertical coordinate transform for reuse in other projects (SODA, nested ADCIRC)
   1. Tom: HYCOM reference code for vertical coordinates
   2. Trond: ROMS reference code for vertical coordinates
10. Horizontal grid transform
11. HYCOM
    1. 1/12 degree resolution
    2. Orthagonal Mercator projection
    3. Arakawa-C grid
12. ROMS
    1. Angle matrix
    • All zeroes for orthagonal projection
    1. Coriolis matrix
    • Which Lat/Long does Coriolis need to be computed?
      • Answer: insignificant difference
    2. Will need Lat/Long dimension for xi, eta, and rho
    3. Chris: Compare Lat/Long dimension values in discrete HYCOM NetCDF for dimensions and variables
    4. Trond: port MATLAB function for metric terms pm, pn
13. Chris: Refactor minihycom for vertical component
14. Chris: Add thickness to minihycom output
15. Next meeting: Trond and Chris on Thursday June 19, 2008
