In situ dedicated sites and campaigns

- Main in situ dedicated calval sites around the World (Credits Noveltis/Legos)
The principal objective is to use observations from tide gauges and other sensors directly on (or near) satellite ground tracks to calibrate the sea-surface height and ancillary measurements made by the satellite as it passes (nearly) overhead.
Several dedicated sites are disseminated around the world. Moreover, some oceanographic campaigns have an altimetry validation goals.
Dedicated sites:
- Bass Strait (Australia): see Watson et al., oral presentation in pdf, OSTST 2009
- Corsica (France): see P. Bonnefond et al., oral presentation in pdf, poster in pdf, OSTST 2009
- Gavdos (Greece): see S.P. Mertikas et al., poster in pdf, and E. Pavlis et al., poster in pdf, OSTST 2009
- Harvest (USA): see B. Haines et al., oral presentation in pdf, OSTST 2009
- Ibiza and L'Estartit (Spain): see J.J Benjamin-Martinez et al., poster in pdf, OSTST 2009
Dedicated campaigns:
- Aramis
- Drake, see S. Melachroinos et al., poster in pdf, OSTST 2009.
