Abstract
Abstract A method is derived for extracting oceanic dynamic height anomaly from collinear (exact repeat mission) GEOSAT short (∼ 1,000 km long) orbit segments. The procedure requires at least 1 year of simultaneous in situ observations and involves: (1) computing with respect to the ellipsoid, a mean sea surface height (SSH) profile solely from altimetry, (2) linear least‐squares removal of tilt and bias from individual SSH profiles with respect to the mean profile, (3) determining an independent mean dynamic height anomaly profile from hydrographic data along the orbit segment, (4) demeaning the tilt‐and‐bias removed individual SSH profiles and addition of the mean in situ dynamic height anomaly, and (5) correcting for concurrently observed dynamic height anomaly at two or more suborbital points during satellite transit. Analysis of the concept suggests root sum squared errors of ±5 cm, which can be reduced by smoothing and longer term measurements along the same orbit segment. A 1‐year comparison betwee...
