[Haoran Xu]

Thanks Martin.May I ask in detail how to calculate the intervals?

Haoran,


you can specify non-constant latitude intervals like this:



 precip_lat_inc    = 0.556914D0, 0.560202D0, 0.560946D0, 0.561227D0, 0.561363D0,

                     0.561440D0, 0.561487D0, 0.561518D0, 0.561539D0, 0.561554D0,

                     0.561566D0, 0.561575D0, 0.561582D0, 0.561587D0, 0.561592D0,

                     289*0.561619268965519,

                     0.561592D0, 0.561587D0, 0.561582D0, 0.561575D0, 0.561566D0,

                     0.561554D0, 0.561539D0, 0.561518D0, 0.561487D0, 0.561440D0,

                     0.561363D0, 0.561227D0, 0.560946D0, 0.560202D0, 0.556914D0,



Note that this is *not* correct for Era5 with 0.25 deg grid spacing, just to illustrate how to do this, and you’ll have to figure out the intervals yourself. With very large forcing data sets you may have to increase some constants in EXF_INTERP_SIZE.h

Dear MITgcm community,

   I am simulating South China Sea current using the configuration in https://data.nas.nasa.gov/ecco/data.php?dir=/eccodata/llc_4320/regions/SouthChinaSea3 Simulating the current in South China Sea  And I am using ERA5 data (0.25°)as atmospheric forcing. The Latitude interval (for 0.14°) in data.exf is not equally spaced distributed. I have not found the configuration for resolution 0.25°(https://github.com/MITgcm-contrib/llc_hires ). So I set the latitude interval equally spaced(file attached).I want to know if this configuration right. Or can anybody teach me how to set this(for 0.25)? Thanks in advance.

Best regards,

Haoran
