<<  How to get heating variable in CCM3?, http://bb.cgd.ucar.edu//viewtopic.php?t=62 >>

Message: Iâ€™ve checked the output variable list in CCM3 user's guide, but I can't find the varible representing heating item at various vertical levels. So here I want to know how to calculate the heating variable in CCM3? Thanks a lot

<br />
<br />First off, please post to one group, and wait a few days before posting
<br />the same question to another group (or many groups), as you have done. It just makes things messier than it needs to be. I dont really want to be answering the same question many times, and I dont want to leave
<br />questions unanswered.
<br />
<br />Now for your question. There is no one term that contains all the heating
<br />rates summed up. Most, if not all of the individual terms will be around.
<br />Look for things like QRL and QRS (long and shortwave heating rates),
<br />DTCOND (heating rates from moist physics),  There will also be one for
<br />the vertical diffusion which I cannot remember off the top of my head.

Message: Hi, Phil,
<br /> Firstly, I'm sorry for posting the same message twice in different groups, since I had thought I had posted the message to the wrong place at the first time because there had been no answers for several days.
<br />
<br /> According to your answer to my question and the variable namelist in CCM3 users' guide, I want to make it clear by summing it up in the following, and hope you could give me some more suggestions.
<br />  The heating in different atmosphere layers includes QRS (solar heating rate), QRL (long wave heating rate), DTCOND (T tendency from adjustment physics) and DTV (T vertical diffusive tendency), wherein,
<br /> DTV is listed by me suggested in the last sentence of your answer. However, I also find some other variables, such as DTH (T horizontal diffusion) and CMFDT (T tendency from moist convection), likely 
<br /> associating with atmospheric heating.
<br />   In a word, the atmospheric heating = QRS + QRL + DTCOND + DTV + DTH (li!
kely) + CMFDT (likely).
<br />   Could you please give me any suggestions about the above expression? Thanks.

<br /> I think you have it almost right, except the CMFDT term will already
<br />be included in DTCOND, so it should be
<br />
<br />atmospheric heating = QRS + QRL + DTCOND + DTV + DTH 
<br />
<br />I am doing this from memory, and I cant take the time to research things
<br />thoroughly.  There are a few things that will confuse things.
<br />1) there may be a term associated with the conversion from kinetic energy dissipation to thermal energy that is not reflected in the above equation.
<br />2) the terms may not balance super precisely because of simple issues like time filtering, and the fact that the terms written to the history file may be staggered from each other by one time step.
<br />
<br />But it should be pretty close.

Message: Why dont you post the last 50 or so lines of the output from this
 script, rather than the script itself. Maybe it will tell us what went wrong.

 It looks like the linker is trying to access entry points it cant find. I suspect
 you built the ncar graphics with one library and the scam gui with a different one.
