    CESM1.2.z - Minor -- lake hydrology bug when sudden intense snowstorm occurs preceeded by warm weather.

    Affected Releases - CESM1.2.z(Bugzilla 1717) For CLM4.5, I found one error that is not just a typo but also shows up in a rarely exercised portion of the code (most likely a sudden very intense snowstorm-- ~8 cm/hr -- preceded by warmer weather) in SLakeHydrology, where the top lake layer...

    CESM1.2.z - Problem with an initial file used in CROP simulations.

    Affected Releases - CESM1.2.z(Bugzilla 1753) The file clmi.ICRUCLM45BGCCROPmp24.0241-01-01.1.9x2.5_g1v6_simyr2000_c130515.nc was interpolated using interpinic for CROP simulations. But, because of Bug 1725, interpinic gave a file that has CROP NOT spunup, but starting up from bare soil. So we...

    CESM1.2.z - clm4_0_60 interpinic fails to properly map from 1.9x2.5 to the 360x720 grid for CRUNCEP.

    Affected Releases - CESM1.2.z(Bugzilla 1634) It will map to other high resolutions like: ne120np4, 0.23x0.31, 0.47x0.61 however. The problem is that it does the mapping, but puts garbage data values (like e317) in some fields that the program does NOT touch. They happen to be very important...

    CESM1.2.z - For CLM4.0, the RCP 8.5 file pftdyn for f09 was NOT correctly updated.

    Affected Releases - CESM1.2.z(Bugzilla 1759) - New good wood harvest is missing from some of the clm40 rcp datasets. A fix was provided in CESM1.1.2 but was not included in CESM1.2.1. In will be fixed in the next CESM1.2.z release.

    CESM1.2.z - Issue with CLM45CNDV trees over Amazon.

    Affected Releases - CESM1.2.z(Bugzilla 1776) - When running CLM45CNDV model (compset: ICLM45CNDV) and after running 400 years, there are no trees in the Amazon. ICNDV works all fine.The behavior has been attributed to Gordon's physiology changes to the model that improve the GPP simulation. This...

    CESM1.2.z - For both CLM4.0 and CLM4.5, crop GDD is incorrect for the first ~20 years.

    Affected Releases - CESM1.2.zFixed in upcoming CESM1.2.2 release.(Bugzilla 1815) - Details and a fix are explained in the bugzilla report.

    CESM1.2.z - The population density is set to 1850 for 2000_control namelist use-cases.

    Affected Releases - CESM1.2.z (Bugzilla 1838) This is true in the cesm1_2_0 release as well as the latest CLM. population density is set to 1850 for 2000_control namelist use-cases. This is due to a bad setting in the following directories... lnd/clm/bld/namelist_files/use_cases...

    CESM1.2.z - irrigated soybean not treated same as rainfed soybean

    Affected Releases - CESM1.2.z(Bugzilla 1867) In modifying the clm to introduce tropical crop pfts, I have come across the following problem:The if-statements in biogeochem/CNAllocationMod.F90 and biogeochem/CNNDynamicsMod.F90 that check for soybean do not include the option for irrigated...

    CESM1.1.z - The interpinic tool does not work properly for input files with multiple glacier elevation classes.

    Affected releases - CESM1.1.z (Bugzilla 1447) Currently, interpinic doesn't use any metadata about the glc_mec columns -- e.g., their topographic height. Details regarding the problem and proposed fixes are included in the bugzilla report.

    CESM1.1.z - Problem setting a user defined initial condition file for a hybrid or branch case.

    Affected Releases - CESM1.1.zFixed in CESM1.2.z(Bugzilla 1625) We've recognized a problem in having the user override the setting of finidat when RUN_TYPE=hybrid/branch. In these cases if you set finidat in your user_nl_clm, it will contradict the value coming in from clm.buildnml.csh -- so...

    Hi,I'm trying to create surface-dataset for my coustom CLM grid. As an intermediate step, I have to generate a mapping file from UGRID_1km-merge-10min_HYDRO1K-merge-nomask_c130402.nc (~125 million grid cells) to destination.nc (~352K grid cells). My job on Titan using 160 cores exceeded...

    ldomain in CESM1.1

    Hi! I have a problem with the land compenent in CESM1.1. I would appreciate if I could get some insight on how to deal with this. I need to specify ldomain from an existing input nc file I have from an older case run with cesm1.0.3, which I did the following way: ./xmlchange -file env_run.xml...
