More realistic air-ice/snow turbulent flux estimates over sea-ice
Last edition: Wikinfo(changed_ts)? by Wikinfo(changed_by)?
The PI is responsible to closely follow the progress of the action, and especially to contact NEMO project manager if the delay on preview (or review) are longer than the 2 weeks expected.
Summary
| Action | More realistic air-ice/snow turbulent flux estimates over sea-ice |
|---|---|
| PI(S) | Laurent Brodeau @ Ocean Next |
| Digest | Implementation of a bulk-transfer-coefficient parameterization for sea-ice-covered regions. This parameterization should consider sea-ice roughness and be able to handle extremely stable surface atmospheric layer conditions typical of sea-ice-covered regions. |

Tests
Test-cas associated with this development:
- Test case name: STATION_ASF (C1D meets SAS). See https://github.com/NEMO-ocean/NEMO-examples/tree/master/STATION_ASF for a more complete introduction.
- Test case functionality: test-case STATION_ASF checks that all bulk algorithms available in NEMO, used to estimate the bulk transfer coefficient for turbulent air-sea and air-ice fluxes, are working properly. This is done by checking that all turbulent fluxes computed at the punctual location of STATION_ASF lie within a reasonable range.
- Test case setup: in STATION_ASF nemo.exe runs on one processor and needs only 2 lightweight netCDF files as input. These 2 files provide hourly time-series of sea-surface variables (SST, SSH), and surface atmospheric state (wind, temperature, humidity and downwelling radiative fluxes), respectively, at the punctual location of STATION_ASF. 1 year of simulation with STATION_ASF takes a few tens of seconds on 1 proc.
- Test case verification value: WILL BE boolean. Each computed turbulent flux (hourly time-series), namely evaporation, wind stress and sensible flux, will be checked for consistency during a whole year. This operation will be carried out with every bulk (air-sea and air-ice) parameterization algorithms available in NEMO, including the testing of different options: cool-skin/warm-layer and wave-pattern input).
- Status of the test case as for now: Exists on the official GitHub? for NEMO. Boolean output not ready yet, version for air-ice fluxes in progress.
