[MITgcm-support] [EXTERNAL] How to select interpolation method in EXF_INTERP_UV

[Sabri MUTLU (MAM-ÇTÜE)]

Thank you Dimitris, 

I am getting following error in the beginning of my run: STOP ABNORMAL END: S/R EXF_INTERP_UV 
Unfortunately, changing the interpolation method doesn't solve the problem. 

What could be the cause of my problem then? 

Best. 
S.

C {inputField}_interpMethod :: interpolation method: =0 : no interpolation ; 
C :: =1,11,21 : bilinear ; =2,12,22 : bicubic ; 
C :: =1,2 for tracer ; =11,12 for U ; =21,22 for V. 

so set: 

uwind_interpMethod = 11 
vwind_interpMethod = 21 

in data.exf under EXF_NML_04 

But watch out, there is a reason why we default to bicubic for wind: bilinear interpolation can cause large spurious gradients and wind stress curl anomalies at the location where wind is specified.

Dear MITgcm Users and Developers, 

I would like to select bilinear interpolation method for external wind data (U,V) instead of default one which is bicubic. Could someone tell me how to change the method for wind data? 

Best.
