[ecco-support] [EXTERNAL] Surface heatflux budget

[Wang, Ou (US 329B)]

Hello,

TFLUX includes the change to the total ocean heat content from changing ocean mass, while oceQnet doesn't. ECCO V4 uses the real freshwater flux boundary condition and therefore changing ocean mass due to evaporation/precipitation/runoff will change the ocean heat content. 

Best,
Ou

    Dear ECCO teams,
    I am trying to decompose the surface heat flux into different components. According to the ecco_v4_py tutorial and the model output description, “TFLUX” is the total heat flux into the ocean, however, when I try to decompose it into different components, I found that:
    
    TFLUX = oceQsw (net downward shortwave) + EXFhl (latent heat) + EXFhs (sensible heat) - EXFlwnet (net downward longwave)
    
    This equation can’t be satisfied, while the another equation:
    
    oceQnet = oceQsw + EXFhl + EXFhs - EXFlwnet
    
    can.
    
    I just wonder what is the difference between oceQnet and TFLUX ? Their values are close to each other, with most of the bias less than 10 w/m^2.
    Or do I miss any term from the model output?
    
    Thanks a lot.
    
    Best,
    Zelun Wu.
