’s newest atlas uses MITgcm
as a means of optimally synthesising data within the framework of a physically accurate general circulation model. By also limiting the time-period over which data was included (the atlas strictly only applies to the period between December 2003 to November 2006 – the beginning of the era of near global Argo
float coverage), OCCA
(short for OCean Comprehensible Atlas, the term ”comprehensible” denoting that the underlying equations of motion are known) (short for OCean Comprehensible Atlas) provides a singularly accurate 3-year “snap-shot” of the world ocean state for that period.
