| Unaggregated Data: |
archive: data in the "archive" folder aims to be a consistent time series for each day. It contains a copy of the "best" t0000 to t0023 forecast files (note: t0024 to t0047 files from the previous forecast can be substituted when a run is missing).
forecasts: data in the "forecasts" folder contains the full forecasts for each model run. note: only the last 8 full model runs are available here. A scrubber deletes all forecasts older than 8 days.

Differences between ESPC-D-V01 and ESPC-D-V02
- Overview
-
ESPC-D-V01 is the "high-resolution deterministic system" described in Barton et al. (2021).
The coupled components have been slightly upgraded for V02:
- NAVGEM
-
Still T681, but increased from 60 to 143 levels with a high altitude option
(model top around 114 km). Updated tropospheric physics.
- HYCOM
-
Eight tidal constituents (V01 only used 5).
- CICE
-
Using version 6.1.4.
- WW3
-
One-way coupling to WW3 at 1/8° resolution (new component in V02, no feedback to the ocean).
TIDES in ESPC-D-V02
HYCOM 41-layer 1/25 degree global (86S to 90N), sunk ice shelf, 8 tides + atmospheric pressure, 49-hour tidal drag filter, Jayne St.Laurent scalar drag, drgscl = 0.3, observed SAL, with ASEnKF correction (Ngodock et al, 2016).
