The main defects at the present time are 1) too much column-integrated water vapor (rtm); 2) an excessively cold region of thlm in the upper troposphere, which appears to have to do with a lack of latent heating or an excess of radiative cooling; 3) excessive cloud fraction and liquid water, which is probably related to the excessive rtm; 4) overly strong updrafts and downdrafts (wp2); 5) insufficient scalar variance (rtp2 and thlp2); and 6) turbulent fluxes that can have a variety of errors in the different simulations we've tried.  Let's use this ticket to record our thoughts and results/plots.\n\n'''Technical spec'''\n\nThe main errors could lie in a number of places, so we'll have to explore and diagnose errors.  For instance,\n\n1)  I think the profile of Ncm should have the same shape as the cloud fraction profile when l_predictnc = .false., but I don't think that it does.  Furthermore, the in-cloud Nc should be roughly constant with altitude in this case, and it should change predictably as we double or halve the droplet number concentration.  I wonder if there is a bug somewhere, or if I just don't understand how l_predictnc works for the Morrison microphysics with SILHS enabled.  If Ncm is wrong, then that could cause a dearth of precipitation at the surface.\n\n2) When we plot CLUBB's rain mixing ratio, it often appears to be larger at the surface as compared to SAM's value.  However, CLUBB has more column-integrated rtm than does SAM.  This seems contradictory.  Either the number of rain drops is very small, and hence the drop fallspeed is very slow, or else there is a spurious source of moisture in CLUBB, or else there is some bug somewhere.\n\n3) Rachel checked that the forcings are identical between CLUBB and SAM input files, but I don't think that the forcings match identically in GrADS output.  E.g., I don't think ```rtm_forcing - rtm_mc``` matches SAM's large-scale forcing output.  I wonder if somehow the forcing values listed in the input files are treated differently within the CLUBB and SAM codes.\n\nThere are other places for exploration as well.\n\nAttachments:\n\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/firsteventmorr.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/firsteventsilhs.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/samfirst.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonbreak.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsbreak.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/rtm_mc.png\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/namelistnc.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/namelistncsilhs.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/kktest.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/changesfcvarcoef.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/alltrue2-ckrain.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/alltrue2-ckrain-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/testmixing.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/mixlengthmult.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/mixlengthmult-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoauto.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoauto-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoaccr.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoaccr-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoaccr-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoaccr.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoauto-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoauto.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoevap-firsts.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morrisonnoevap.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoevap-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsnoevap.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-default.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-ck20-nur500.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/testallwithckandnu.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/boostckandnu-june6.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/morr-silhs-ckandnu.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-noevappre.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-noaccr.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-noautoaccr.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/budgets-noauto.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/r6303-plume-ice-xp2.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/r6303-plume-ice-xp2-inputricem.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/r6303-plume-ice-xp2-inputricem-comparealltrue-first.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/microphysicssourcebudget\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/precision-timestep.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/silhsrepos-double10s.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/singlensteptest3.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/doublensteptest3.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/alltrue-prescribeup2vp2.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/r6481-comparemicro.maff\nhttp://carson.math.uwm.edu/trac/clubb/attachment/ticket/544/r6481-convection-morrison-covar.maff\n\nMigrated from http://carson.math.uwm.edu/trac/clubb/ticket/544\n```json\n{\n    \"status\": \"closed\", \n    \"changetime\": \"2013-08-26T19:53:16\", \n    \"description\": \"\\n'''Introduction'''\\n\\nRachel has been investigating CLUBB's simulations of the arm_97 case (ticket:536, ticket:542).
