Below are the proposed Harvard modeling domains for AOSN-II. The Harvard domains are outlined in red. The outer limits of the California Current (300km-1000km) are drawn in dashed white lines. The outer limits of the California Undercurrent (100km-200km) are drawn in dashed yellow lines. Also in these diagrams are: the resolution of each domain; the color-filled contours of topography; the locations of the M1 & M2 moorings; and, the location of points Ano Nuevo and Sur.
| California Current System (Large) | Central California (Middle) | Monterey Bay (Small) | |
| Resolution | 0.081° (~9km) | 0.027° (~3km) | 0.009° (~1km) |
| Size (nx,ny,nz) |
119x84x20 (~1062x747km) |
119x144x20 (~354x429km) |
119x144x20 (~118x143km) |
| Domain center | 35.06°N, 127.01°W | 36.22°N, 123.56°W | 36.61°N, 122.38°W |
| Domain rotation | 31.6° | 31.6° | 31.6° |
The small domain comfortably encompasses point Ano Nuevo to the north and point Sur to the south. It includes the area of active data sampling and is sized to run in equal time with the middle domain.

Comparison of domains with some results from Observing and Modeling the California Current System by Miller et al. Text with figures taken verbatim from the paper.
"Mean 15-m velocity (black arrows, 15 cm/s) and its variance (red crosses, 500
cm2/s2) in the California Current System (CCS) and eastern
Pacific from available surface drifters (National Oceanic and Atmospheric
Administration Global Drifter Center,
http://www.aoml.noaa.gov/phod/dac/gdc.html
) during the period 1985-1998. Symbols are plotted at the center points of a
2° grid." |
"SST (color in °C) and sea level height (2 cm contour interval) on a
typical May 1 from the DieCAST CCS model showing the types of upwelling
filaments, eddy structure, and equatorward jet typical of modern CCS
models." |
