Development and Preliminary Validation of an EnKF-Like Image Assimilation System for the Common Land Model

Quickstart for CoLM Version 2014 12/24/2014 1. Before start - Download the source code (colm2014_src.tar.gz), land surface data (data.tar.gz), and atmospheric forcing data (CRUNCEP for simple) firstly. - Uncompress the colm2014_src.tar.gz and data.tar.gz, the major directories are shown below clm/ --- source code include/ --- include directory main/ --- CoLM main source code mksrfdata/ --- make surface data mkinidata/ --- make initial data [CaMa]/ --- coupled CaMa-Flood Model run/ --- job scripts postprocess/ --- post process data/ inputdata/ --- input data atm/ --- atmospheric forcing data srf/ --- land surface data [cama]/ --- CaMa-Flood model data CLMrawdata/ --- raw data for making land surface data - Put the forcing data in the corresponding sub directories under directory data/inputdata/atm. 2. System environment setting - Edit clm/include/Makeoptions to set compiler info and NetCDF library path. 3. Model setting - Forcing data time range. Edit clm/main/user_specified_forcing.F90 to set the available data time range (MARK #1 +3 lines for CRUNCEP). - Edit clm/run/jobclm.csh to set o case name (MARK #1) o model running time (MARK #2 +4 lines) o CoLM source code directory (MARK #3) o input data directory (MARK #4) o case directory (MARK #5) 4. Run model - Go to directory clm/run/ and ./jobclm.csh 5. Model output - Model running time information: go to case directory, check file ${CASE_NAME}/exe.timeloop.log - Model results: ${CASE_NAME}/output/${CASE_NAME}_2D_Fluxes_YYYY-MM is the binary CoLM output. you could use progrom clm/postprocess/bin2netcdf (make first) to convert it to a NetCDF file. $./bin2netcdf ${CASE_NAME}_2D_Fluxes_YYYY-MM [ncar] - ${CASE_NAME}/output/CaMa/ includes the output of CaMa-Flood model. 6. Trouble shooting - For compiling error, see ${CASE_NAME}/xxx.log files - For job error at very beginning of running, check the input data file path first - For any other problems or questions please feel free to contact us at [email protected]
