As part of the process of generating the CESM executable, the utility, check_input_data located in each case directory is called, and it attempts to locate all required input data for the case based upon file lists generated by components. With valid git and svn clients installed on the machine where CESM will be built and run, the user may download the latest development or production release by running one of the following commands: * You should use the most recent version of the model that is available unless you are trying to replicate previous results or create a branch run from a previous experiment. appropriate subdirectory of $DIN_LOC_ROOT. Getting the source code CESM is a free, open source model. The summary of time series processing is output in Output 7.1.1. DIN_LOC_ROOT_CLMFORC determine where you should expect They are designed to be useful to a variety of researchers in the CESM community. For generic machines, this variable is set via the --input-dir argument to create_newcase. CESM Project. However, on supported machines (and some non-supported Getting up and running with CESM NCAR is sponsored by the National Science Foundation Cécile Hannay Climate and Global Dynamics (CGD), NCAR The Parallel Input/Output libraries or “PIO” are used within the CESM for more efficient reading and writing. The coupled CICE model requires a minimum of two files to run. Example below showing a clean status output for all externals after running checkout_externals with the status flag, note there are no characters in the first two columns of output. However, on supported machines (and some non-supported machines), data already exists in the default local filesystem input data area as specified by $ DIN_LOC_ROOT (see below). If you want the input data files to stick around for future CESM runs, you may want to consider changing the path to somewhere in your project directory to avoid the scratch purge. For supported machines, this variable is preset. First try rerunning ./manage_externals/checkout_externals If there is still a problem, try running with logging turned on: Check the manage_externals.log file to see what errors are reported. CESMwith these components. About CESM2. CESM version 2.0.1 (the original public-release version of CESM2, and scientifically identical to public version 2.1.0) was run on a nominal 1-degree finite-volume horizontal grid for 30 years to assess the model's ability to represent atmospheric rivers (extreme precipitation events) and their related weather patterns. The individual input files described are described below. needs $DIN_LOC_ROOT to be populated with input data in order to run The source code, build and run scripts can be downloaded as described in the CESM 2.1.0 quick guide. server. Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR). The files in the subdirectories of $DIN_LOC_ROOT should be write-protected. as part of the release via data from the CESM subversion input data Use the links below to view other CESM release instructions. If the required data is not found on local disk in $DIN_LOC_ROOT, then the data will be downloaded automatically by the scripts or it can be downloaded by the user by invoking check_input_data with the --download command argument. For what to expect when interacting with a Subversion repository, see Data are provided on the CESM hybrid-sigma grid for comparison with CESM simulations. The full directory structure of the original directory is At this point, you must obtain the required data from the Renewal requests also require CESM working group co-chair and CSEG approval. mkmapdata.sh uses the above SCRIP grid input files to create SCRIP mapping data files ...

The directories in $DIN_LOC_ROOT should generally be group writable, so the directory can be shared among multiple users. required component input datasets in the However, on supported machines (and some non-supported machines), data already For model output data, see the Experiments and Output Data section of this website. For all machines, input data is provided as part of the release via data from a subversion input data server. the presence of the required input data files in the root directory If all required data sets are found on local disk, If the directory pointed to by CESMDATAROOT does not exist, create it with the mkdir command. The CESM project is supported primarily by the National Science Foundation (NSF). placed in the appropriate subdirectory of $DIN_LOC_ROOT. The script $CASEROOT/check_input_data determines Then to checkout a specific CESM release tag type, for example CESM2.0.1: To checkout all the individual model components, run the checkout_externals script: The checkout_externals script will read the configuration file called Externals.cfg and will download all the external component models and CIME. Each release includes the complete collection of component model source code, documentation, and input data. first generate a virtual copy of $DIN_LOC_ROOT To use this script, use the -h optiion Input datasets are usually on the same grid but in some cases, they can be interpolated from regular lon/lat grids in the data models. The latest CESM development release is CESM2.2.0. The more info the better. The namelist input file (pop2_in and user_nl_pop2) will need to be changed as well. The sign convention is the same as CESM's: shortwave fluxes are positive downward, and longwave fluxes are positive upward. This site depends on Javascript for full functionality. For all machines, input data is provided If you experience problems such as checkout_externals hanging, run: Permanently accepting the certificate when prompted, then retry the CESM download starting over at the top of these instructions. The heading (e.g. If a problem was encountered during checkout_externals, which may happen with an older version of the svn client software, it may appear to have downloaded successfully, but in fact only a partial checkout has occurred. For supported machines, this variable is preset. To run CESM or RASM with VIC, several sets of input data are necessary: Input Configuration File: This file lists the individual input files used by the CESM driver. 2018a, b). The amount of modification of CESM depends on which version of CESM is being used. This shared directory may be used by any ARCHER users, and not just NCAR (n02) users, and may only be read from. View the CESM2 release series information to learn … Input datasets are needed to run the model. 5. can independently verify that the required data is present locally by The components influence each other only through the coupler. When contacting the Subversion server for the first time, you may need to accept an authentication certification. if the required data files for the case exist on local disk in the NCAR has copied a subset (currently ~70 TB) of CESM LENS data to Amazon S3 as part of the AWS Public Datasets Program. interaction with the Subversion input data server.

The total data volume of the original dataset is ~500TB, which has traditionally been stored as ~150,000 individual CF/NetCDF files on disk or magnetic tape made available through the NCAR Climate Data Gateway for download or via web services. using the following commands: If input data sets are missing, you must obtain the datasets from area as specified by $DIN_LOC_ROOT (see below). All of the necessary data will be served up by a special data server sitting in the department, so you should be able to run this code to interact with the data on any computer that is connected to the internet. Details regarding the CESM checkout process are available in the CESM GitHub repo README , to see more details regarding the checkout_externals script from the command line, type: To confirm a successful download of all components, you can run checkout_externals with the status flag to show the status of the externals: If there were problems obtaining an external, you might see something like: This might happen if there was an unexpected interruption while downloading. The input data necessary to run all supported component sets is made available from a public Subversion input data repository. wr50a) describes the domain grid used and is used by build_vic_namelist via the LND_GRID environment variable set by the CESM build system. This CESM shared input data directory is located at /work/n02/shared/cesm/inputdata/. You will still be required to input your CESM SVN developer's credentials in order to access the form. Note that the inputdata repository has much more data in it than you need to run CESM1.0 ---- DO NOT attempt to svn checkout the whole input data repository. dataset(s) names that are different than the names in $DIN_LOC_ROOT, In addition, several input template files may need to be changed. CESM can be configured with many combinations of its components (CAM, CLM, POP, CICE, …) some of which may be ‘data’ components, which merely read in data from some external source and pass it to the other, active, components to use. A local input data directory should exist on the local disk, and it also needs to be set in the CESM scripts via the variable $DIN_LOC_ROOT. populated with user-specified input datasets.
