Licenses/restrictions placed on the data: Public Domain with access granted to public on 10/31/2020. Delay of public access is put in place to prevent access before official publication. The public access date will be updated accordingly. Although this dataset uses a Public Domain license due to its derival from an open source software (WRF-ARW), please see (6) to cite the appropriate publication. 2.

Filename: stanford_et_al_2020_metadata.docx Short description: Metadata file describing the files needed and instructions for reproducing the simulations in Stanford et al. (2020). B. Filename: namelist.input Short description: The namelist.input file needed for running the simulations in Stanford et al. (2020). The namelist.input file is the user file that controls the model setup. C. Filename: module_diffusion_em.F Short description: The modified mixing module used to perform stochastic mixing simulations. D. Filename: module_first_rk_step_part2.F Short description: Modification to this file must be used in conjunction with module_diffusion_em.F. E. Filename: input_sounding_May11 Short description: Text file including atmospheric state variable and horizontal wind profiles used to initialize idealized simulations of the 11 May squall line case. F. Filename: input_sounding_May20 Short description: As in (E), but for the 20 May squall line case. 2. Relationship between files: The metadata file is the overarching file with instructions for the reproduction of simulations in Stanford et al. (2020) and describes the relevant use of the following 5 files. The namelist.input file is used directly to control WRF model settings. The two *.F files are the necessary modified files needed to create the stochastic mixing scheme. The two "input_sounding" text files are used to initialize the simulations with horizontally homogenous thermodynamic and kinematic conditions. 3. Additional related data collected that was not included in the current data package: The actual output files of the simulations from Stanford et al. (2020) are not included due to the very large size of the collective files (> 10 TB). Thus, this dataset provides instructions and relevant files needed to reproduce the simulations. 4. Are there multiple versions of the dataset? no If yes, list versions: Name of file that was updated: i. Why was the file updated? ii. When was the file updated? Name of file that was updated: i. Why was the file updated? ii. When was the file updated? -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Details on the experimental design can be found in Stanford et al. (2020). See (2) for more details regarding processing of the data from the WRF-ARW v3.9.1 source code. 2. Methods for processing the data: Files modified to create the stochastic scheme (module_diffusion_em.F and module_first_rk_step_part2.F) originated from WRF-ARW v3.9.1 source code. Modifications to this code are described in stanford_et_al_2020_metadata.docx. The namelist.input file used to control model setup is also included. The simulations were initialized with a sounding (input_sounding_May11 or input_sounding_May20), which are simply text files containing the atmospheric state variables and horizontal winds needed to initialize the idealized model. These soundings are based on observed soundings from the Midlatitude Continental Convective Clouds Experiment (MC3E), the data for which are freely and publicly available at https://adc.arm.gov/discovery/#/. Further details about the model setup, including justification for the model setup, can be found in Stanford et al. (2020). 3. Instrument- or software-specific information needed to interpret the data: The simulations must be performed with WRF-ARW v3.9.1 (doi:10.5065/D6MK6B4K). 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: N/A 6. Describe any quality-assurance procedures performed on the data: Resulting data from the stochastic mixing scheme is physically interpreted in Stanford et al. (2020). Proper interpretation among the manuscript authors and the the peer review process ensure the data is of appropriate quality. 7. People involved with sample collection, processing, analysis and/or submission: Drs. McKenna Stanford, Hugh Morrison, and Adam Varble ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: [FILENAME] ----------------------------------------- 1.
