Definition of internal metrics
3.1. Common grid
All the systems interpolate their outputs on the so called MERSEA grid
with:
x A horizontal resolution of 1/8°.
x A vertical resolution with 8 vertical levels (at 5, 30, 50, 100,
200, 500, 1000, and 2000 meters) in the Mediterranean
basin.
x And 12 vertical levels (at 5, 30, 50, 100, 200, 400, 700,
1000, 1500, 2000, 2500, and 3000 meters) in the North
Atlantic.
The common geographical domain extends from 10°N to 68°N for the
North Atlantic and covers the whole Mediterranean Sea excluding the Black
Sea from 6°W eastward.
Class 1 to 3 diagnostics are provided on a real time basis by all teams
through their OPeNDAP server for the daily mean (or snapshots for
HYCOM-US) best estimates fields (the best estimate corresponds to the best
analysis field that each system can produce), as well as for the sixth day
forecast.
