[NARCCAP-discuss] narccap-discuss Digest, Vol 18, Issue 3

[Melissa Bukovsky]

Hi Jonas,

Are they identical over water?  They should be.  If they're not over 
land by that percentage or more, then one may include transpiration and 
one may not.  It's also possible that one is instantaneous (this may be 
latent heat) and one is a 3-hour average (evps should be this way).

Cheers,
Melissa
