[MITgcm-support] Sample pTracer using flt package

[钱钰坤]

Hi all,


I've inserted an passive tracer (using ptracer package) and deployed
Lagrangian particles (using flt package) simultaneously into a dynamic flow.
I wanted to sample the tracer value along each Lagrangian float but I only
found the following five lines of code in flt_traj.F:


CALL FLT_BILINEAR  (ix,jy,uu,uVel,  kp,1,bi,bj,myThid)
CALL FLT_BILINEAR  (ix,jy,vv,vVel,  kp,2,bi,bj,myThid)
CALL FLT_BILINEAR2D(ix,jy,pp,etaN,     0,bi,bj,myThid)
CALL FLT_BILINEAR  (ix,jy,tt,theta, kp,0,bi,bj,myThid)
CALL FLT_BILINEAR  (ix,jy,ss,salt,  kp,0,bi,bj,myThid)



which means the flt can only sample the basic flow states (u, v, eta, theta, and salt).


I wonder if there is an easy way to achieve this by modifying the code slightly as:


CALL FLT_BILINEAR  (ix,jy,ss, pTracer(, , , , , iTracer),  kp,0,bi,bj,myThid)


and using the result to replace the salt which I do not care about?


If yes, how to modify the #include or variable declarations at the beginning of flt_traj.F?


Many thanks.
