[ecco-support] [EXTERNAL] Question about the atmospheric state estimation in MITgcm

[Wang, Ou (US 329B)]

Hello,

I suspect some runtime parameters in data.exf were not set correctly when you added snow precipitation forcing. Could you post the error along with your data.exf to help diagnose the problem?

I also wanted to point out that although the first guess of surface forcing was from the ERA Interim re-analysis fields, it has been adjusted by the optimization for ECCO Version 4 state estimates.

Best,
Ou

Dear ECCO group

I am a graduated student in the school of atmospheric science from Nanjing University. I've recently run the MITgcm model (llc90 version) for my study and I found that the near surface atmospheric state estimation was driven by the ERA Interim re-analysis fields. For my research need, I want to change the near surface atmospheric state estimation by adding the snow precipitation. So I download the snowfall data and try to input the data into the model. However, the model kept report errors. Is there any special process in dealing with the input data? I would be very grateful indeed for any help you could give me.

Best wishes
