[ecco-support] [EXTERNAL] EXFqnet over the sea ice

[Wang, Ou (US 329B)]

Hello Hiroyuki,

"EXFqnet" is the net heat flux into the ocean if there were no sea-ice. Masking out "EXFqnet" by sea-ice coverage is one way to get the ocean-atmosphere heat flux you are looking for. 

If you were actually looking for net heat flux into the ocean, "oceQnet" is the field you would want to use. "oceQnet" is the net heat flux into the ocean from air and sea-ice. Below is a bit more detailed description from the meta data of ECCO V4r4 "oceQnet" files:
Net heat flux into the ocean surface from all processes: air-sea turbulent and radiative fluxes and turbulent and conductive fluxes between the ocean and sea-ice and snow.

Best,
Ou Wang

    Hi all,

    I am a user of ECCO v4r4. I have a question about surface heat flux in ECCO data.

    "EXFqnet" is defined as "Open ocean net air-sea heat flux", but I see very large value over the sea-ice regions. How should this be interpreted?

    If I want to see pure open ocean-atmosphere fluxes, should I mask them with appropriate sea ice data?

    Best regards,
    Hiroyuki TOMITA
