Message: Dear cam-users
<br />
<br />
<br />Having changed the code somewhat to include aerosols in the model CAM2.01., FV,
<br />the meteorology of the model changed a little bit. It can not be seen until 
<br />at least model day 5 running on a SGI 3000. Even worse running the model one more time with the same setup yielded a slightly different answer First I asssumed I had done
<br />an array bug, but then I found out that only including new trace species 
<br />was enough to make this problem occur.
<br />
<br />The test I did was to change pcnst to 12 in params.h.
<br />readtrace to false in preset.F90 (hm what happens then to the water cycle?)
<br />nusr_adv to 11 in preset.F90
<br />
<br />
<br />Have anyone observed this behaviour before?
