METHODOLOGICAL INFORMATION

  1. Description of methods used for collection/generation of data: Cloud Resolving Model data (files: "L305_cond_2D_0000725220.nc", "sam_rce_domain_averages.nc", and "GATE_IDEAL_L305_cond_256_0000725220.nc") is generated using the System for Atmospheric Modeling version 6.10.3. See publication for details.

  2. Methods for processing the data:
    Satellite observations (file: "MODIS_EPSILON_2002-07_to_2019-09.nc") were obtained by dividing surface precipitation from TRMM 3B42RT by MODIS condensed water path.
    SAM data for "sam_rce_domain_averages.nc" is processed by taking the average over the x-y domain in each simulation, then calculating precipitation over condensed water path (liquid + ice).

  3. Instrument- or software-specific information needed to interpret the data: N/A.

  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: N/A.

  7. People involved with sample collection, processing, analysis and/or submission: Dr. Nicholas Lutsko provided the method to modify source code in SAM to output condensation rate from the model. Models were run by Ryan Li.
