The main objective of our Jason-1 investigation is to combine altimeter data from several missions for sea level and ocean circulation monitoring. Combining TOPEX/POSEIDON (T/P), ERS-1/2, GEOSAT Follow-On (GFO), ENVISAT and Jason-1 data will allow us to map sea level variations over a long time with high accuracy and very good resolution. This opens up new avenues for oceanographic studies using satellite altimetry.
