w from vorticity balance: On depth levels On isotherms
Old versions (rel 300m): On depth levels On isotherms
Compare w from vorticity balance to Ekman w:
- Sverdrup balance: (B/f)*Int(Vg)dz = Curl(Tau/f) (Quikscat) Different aspect ratio All wind products compared
  - Add Levitus 500m Vg: (B/f)*Int(Vg)dz Levitus Vg 500/1000m
- FSU winds ECMWF winds ERS blended scat winds ERS V2 Quikscat winds
- Quikscat winds 4x1x30: As above (w at sfc rel 450m) (extend to 2°N) w relative to 150m
  Curl - Vg Differences: To 5°N To 2°N
- All winds compared
- Correlation of w's as a function of latitude Extend to Equator Overlay 2 calculations Signal RMS

Check reference level stuff:
- From Levitus: w at 0 relative to 300 and 1000m Difference w at 300m
- Sections extending below 300m along 8.5°N: XBT Temp Levitus sections: Temp Salt Sigma-t Combined
- Mean temperatures at 350, 400, 450m

    w based on various reference levels:
    Relative to level surfaces: w at sfc rel levels  with Vg relative to 450m
    Relative to isotherms: w at sfc rel isotherms  with Vg relative to 450m  isotherms depths to correspond
    w at sfc and at 17°C
