File Naming Convention

Each variable should be submitted as a separate output file following the naming convention: .nc where each field uniquely identifies the model configuration, experiment, and variable. The should include the standard model name (and version, if applicable). If multiple simulations from the same model are submit- ted with different physics configurations (e.g., WRF or SAM), these differences should instead be specified in . Please keep entries concise, but sufficiently descriptive. For default model configurations, simply use control for . should be either single or double, corresponding to the single-pulse and double-pulse experiments, respectively. should be either 2D or 3D, depending on whether the submitted variable is two-dimensional or three-dimensional, as defined in Tables 1 and 2.

For example, a submission from the SCREAMv1 model at 3 km resolution using the control or default configuration of that model for the single-pulse experiment, for surface precipitation, would be:

SCREAMv1_3km_control_single_2D_pr.nc

As another example, if SCREAMv1 were submitted for the double-pulse ex- periment using a configuration with the 1.5 TKE turbulence option and MG2 microphysics, the filename might look something like be:

SCREAMv1_3km_1p5tke.mg2micro_double_2D_pr.nc
