I have a very general question about the JRA-do and how it forces the thermodynamic changes at the surface of the ocean. When I read that e.g. air temperature is prescribed by JRA55-do, does this mean the same air temperature was prescribed in all experiments JRA55-do is used as the forcing e.g. RYF…

No, the forcing is not the same. IAF stands for interannual forcing. It’s the full JRA55-do record. Something like 60 years. RYF stands for repeat-year-forcing. It’s only one particular year of the IAF (the most neutral one) that we loop on repeat.

Also, to note (in case it wasn’t clear) that JRA55 provides things like surface air temperature, wind speed, humidity, etc – then we have another “Data driven atmosphere model” (known as YATM) which applies the bulk formulae to calculate ocean-atmosphere fluxes (or ice-atmosphere fluxes) of both hea…

Thank you both. This was helpful and answers my question. Cheers

for completion, @ribeirosantosn could you mark the response(s) that answered your question with the tick box at the bottom (to the left of the like-heart button)? it’s good practice so that people in the future can find the answer – might not be so relevant in this small thread, but in a thread with…
