In 2019 the kelvin was redefined in terms of Boltzmann constant. Here we outline implications that redefinition for realization and dissemination unit temperature. We describe progress towards realizing prospects temperature traceability into 2030 s.

Two three-dimensional primitive equation numerical ocean models are applied to the problem of internal Kelvin waves and coastal upwelling in the Great Lakes. One is the Princeton Ocean Model (POM) with a terrain-following (sigma) vertical coordinate, and the other is the Dietrich/Center for Air Sea Technology (DIECAST) model with constant z-level coordinates. The sigma coordinate system is part...
