The source code is showed as below. My questions here are if I want to use metric unit in precipitation, can I just change the source code and rebuilt the NCL? Or are there any other ways I can try?</span></div><div><span style="line-height: 1.7;"><br></span></div><div><span style="line-height: 1.7;">Thanks a lot!</span></div><div><span style="line-height: 1.7;"><br></span></div><div><span style="line-height: 1.7;">Ce Zhu</span></div><div><span style="line-height: 1.7;"><br></span></div><div><span style="line-height: 1.7;"><br></span></div><div><div> IF (IPRSNT(14).EQ.1 .AND.
