Hi, I have a question about the grids of some variables. The grids: XC, XG, YC, YG, RC and RG. My output files are like: U.0000691200.data and U.0000691200.meta What horizontal and vertical grids do these variables (U, V, Eta, S, T, UUtave, UTtave, ......) use? I searched in MITgcm manual, but could not find the information. Best, Ping
