A FAQ to explain how to print min and max value of exchanged fields through OASIS : ​https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowtohaveminandmaxvalueexchangedthroughOASIS

Fields exchanged in IPSL-CM6 coupler

• Variables in OASIS atmosphere:
  • sent to ocean :
    • 1 per sea ice time step (2 ocean time steps) : COTAUYYV, COTAUYYU, COTAUZZU, COTAUXXV, COTAUXXU, COTAUZZV, COWINDSP, COTOTRAI, COTOTSNO, COTOTEVA, COICEVAP, COQSRMIX, COQNSMIX, COSHFICE, CONSFICE, CODFLXDT
    • 1 time per day : COCALVIN (3 times), COLIQRUN
  • received from ocean : SISUTESW, SIICECOV, SIICTEMW, SIICEALW, CURRENTX, CURRENTY, CURRENTZ

COTAU[X,Y,Z][U,V] are wind stress components in a 3D geocentric referentiel. It's an average over sea-ice and free ocean (weighted by their respective fraction).

• Variables in OASIS ocean:
  • received from atmosphere :
    • 1 per sea ice time step (2 ocean time steps) : O_OTaux1, O_OTauy1, O_OTauz1, O_OTaux2, O_OTauy2, O_OTauz2, O_Wind10, OTotRain, OTotSnow, OTotEvap, OIceEvap, O_QsrMix, O_QnsMix, O_QsrIce, O_QnsIce, O_dQnsdT
    • 1 time per day : OCalving, OIceberg, OIcshelf, O_Runoff
  • sent to atmosphere: O_SSTSST, OIceFrc, O_TepIce, O_AlbIce, O_OCurx1, O_OCury1, O_OCurz1

O_OCur[x,y,z][1,2] are surface velocity components in a 3D geocentric referentiel. It's an average over sea-ice and free ocean (weighted by their respective fraction).

• Fields are exchanged every sea ice time step (2 ocean time steps). Except COLIQRUN et COCALVIN, exchanged once a day.

• Weights have been prepared offline.
