Advances since SMP started...
•Full suite of satellite sensors are in orbit
–Ocean color
–Altimetry (sea level, eddies, dynamics)
–SST (air-sea exchanges)
–Scatterometry (wind stress)
–Passive & active radar (sea ice, SST, precip)
•Data are freely available (but difficult to use)
•Get forcing & some BGC response (just not all)
