Abstract:

A large eddy simulation is used to model the 3D mixed layer on scales from 4 m to 20 km. This dataset contains snapshots of the (dimensionless) passive tracer variables as described in an associated publication (Smith et al., 2016). The state variables at other timesteps during spinup are associated with other datasets that are available under GRIIDC Unique Dataset Identifiers (UDIs) R4.x265.241:0003 and R4.x265.241:0001. The snapshot number is given as a dimensionless time. Location within the domain is given as x, y, zu (cell center), zw (upper boundary of cell), with units of meters. Dataset also includes passive tracer concentration (dimensionless, equivalent to g/kg) of a variety of artificially-induced tracers. Some are initialized at depth, some are injected through the surface. This dataset supports the publication: Smith, K. M., Hamlington, P. E., & Fox-Kemper, B. (2016).

Purpose:

This tracer data is used to better understand the consequences of the large eddy simulation on the transport of nutrients, oil, etc.

Data Parameters and Units:

Tracer [concentration of a passive tracer (dimensionless, equivalent to g/kg)]; x [tracer position in horizontal grid units, meters]; y [tracer position in horizontal grid units, meters]; zu [tracer position in vertical grid units for the horizontal velocities (cell center), meters]; zw [tracer position in vertical grid units for the horizontal velocities (upper boundary of cell), meters]; snapshot [numbering system to identify distinct model state snapshots, unitless]. The dataset also includes a readme file.
