Data accompanying the paper titled: An Evaluation of Algebraic Turbulence Length Scale Formulations. This repository contains configuration files, example of sub-domain statistics, post-processing script and figures for five idealized simulations run with LES model MicroHH (van Heerwaarden et al., 2017): ARM, BOMEX, RICO, DYCOMS and GABLS1. All case were run with version 2 of the MicroHH model: https://github.com/microhh/microhh2 . A total of five idealized cases with different ABL conditions are used for the evaluation of the turbulence length scale formulations: a continental cumulus case based on data from the Atmospheric Radiation Measurement (ARM) program at the Cloud and Radiation Testbed site in Oklahoma (Brown et al. 2002; Lenderink et al., 2004), a stratocumulus case with drizzle based on data recorded during the first research flight (RF01) of the second period of the Dynamics and Chemistry of Marine Stratocumulus (DYCOMS-II) campaign (Stevens et al., 2005), a stable boundary layer case based on data from the Global Energy and Water Cycle Experiment (GEWEX) Atmospheric Boundary Layer Study (GABLS1) (Holtslag, 2006; Beare et al., 2006; Cuxart et al., 2006), a trade-wind cumulus case from the Barbados Oceanographic and Meteorological Experiment (BOMEX) (Siebesma et al. , 2003), and a precipitating shallow cumulus case from the Rain in Shallow Cumulus over the Ocean (RICO) campaign (Rauber et al., 2007). The files are organized in the following way: The 'conf' folder contains the MicroHH configuration files (.ini) for each case. Examples of the sub-domain statistics produced by the MicroHH model for the largest sub-domain size (data for smaller sub-domain sizes are too large to be uploaded to this repository) are located in the 'LD' folder. Python script 'calc.py' computes diagnosed length scales and length scales computed according various formulations from the sub-domain statistics. The resulting data are stored in NetCDF files in the 'LDpost' folder. The figures for the publication are prepared by the 'plot.py' script and are located in the 'figures' folder., {"references":["van Heerwaarden, C. C., van Stratum, B. J. H., Heus, T., Gibbs, J.
