Mr. Carnes et al., INFERENCE OF SUBSURFACE THERMOHALINE STRUCTURE FROM FIELDS MEASURABLEBY SATELLITE, Journal of atmospheric and oceanic technology, 11(2), 1994, pp. 551-566
Satellites now provide global measurements of the ocean's surface heig
ht and temperature. Ocean climatologies for the northwest Pacific and
northwest Atlantic Oceans that relate sea surface height, sea surface
temperature, day of the year, latitude, and longitude to temperature a
nd salinity profiles were produced using least-squares regression. The
se analyses use over 33 000 profiles of historical temperature and sal
inity data and are considerably streamlined and compacted by expressin
g each profile in terms of empirical orthogonal functions. Evaluations
and error analyses of the climatologies, including a comparison to th
e navy's Generalized Digital Environmental Model, were performed and d
ifferences between the regions are discussed. Two sample vertical sect
ions are shown to be closely reproduced with the climatologies. Climat
ologies based on surface height and temperature are found to offer con
siderable improvement over climatologies based only on position.
