[MITgcm-support] Variables in pickup files

[Martin Losch]

Hi Peng,

from model/inc/DYNVARS.h:

C     State Variables:
C     etaN  :: free-surface r-anomaly (r unit) at current time level
C     uVel  :: zonal velocity (m/s, i=1 held at western face)
C     vVel  :: meridional velocity (m/s, j=1 held at southern face)
C     theta :: potential temperature (oC, held at pressure/tracer point)
C     salt  :: salinity (ppt, held at pressure/tracer point)
C     gX, gxNm1 :: Time tendencies at current and previous time levels.
C     etaH  :: surface r-anomaly, advanced in time consistently
C              with 2.D flow divergence (Exact-Conservation):
C                etaH^n+1 = etaH^n - delta_t*Div.(H^n U^n+1)
C  note: a) used with "exactConserv", necessary for Non-Lin free-surf and mixed
C           forward/backward free-surf time stepping (e.g., Crank-Nickelson)
C        b) same as etaN but not necessarily at the same time, e.g.:
C           implicDiv2DFlow=1 => etaH=etaN ; =0 => etaH=etaN^(n-1);
