Hello, I am trying to run CLM4.5 (component set: ICRUCLM45BGCCROP) with irrigation turned on, with the surface data and initial data downloaded from the input data server on ucar.edu. When the irrigation turned off (irrigate = .false. in user_nl_clm), the cases ran normally. However, once I turned on irrigation by setting irrigate = .true. in user_nl_clm and CLM_BLDNML_OPTS = "-irrig .true." , the runs were not successful and generated different errors.
1. PFT weights are SIGNIFICANTLY different from the input finidat This occurs when I used surface data and initial data with older date-stamp (eg. 130419, 130515) , it clearly stated that I should use the interpinic function under CLM tools to interpolate the initial data. I haven't tried this function yet, so I want to ask whether someone can successfully run with irrigation after interpolating the initial data. Thanks. 2. PCT_PFT not in surface data This occurs when I used more recent surface and initial data (date-stamp 141226, 150108 for example), I found that for these .nc files, only PCT_CFT ("percent crop functional type on the crop landunit (% of landunit)") can be found instead of PCT_PFT ("percent plant functional type of gridcell"). I am not sure whether we can modify the data in these recent surface data such that the system can read it.
3. Mismatch of input dimension 79 with expected value 25 for variable lsmpft This error occurs when I tried to use data set with more PFT (eg. clmi.ICRUCLM45BGCCROP.78pfts.levis_reinterp.1.9x2.5_g1v6_simyr2000_c160127.nc and surfdata_10x15_78pfts_simyr2000_c160127.nc) and I am not sure whether we can change the expected value of lsmpft. These are the errors I encountered and I am not sure how to successfully run a crop model with irrigation on. It would be great if someone can share what dataset should be used during an irrigation run. Thanks. Jacky
