nudge one kind of passive traces
Hi all:
If I want to nudge one kind of passive traces during simulating, then first I should make the climatology file of this trace. Should I define the structure of this climatology variable in varinfo.dat file ?
Thank you!

I think you can active Q_PSOURCE and TS_PSOURCE and set Qbar、Qsrc and Tsrc in ana_psource.h file.
The ana_psource.h file can not only sets the imformation for T&S, but can set the imformation for other tracers.
