Codes and Data for Droplet Collision Enhancement by Electric Fields

Shi-An Guo provides codes and data for the 2021 ACP paper, “The enhancement of droplet collision by electric charges and atmospheric electric fields.” The dataset includes precomputed collision efficiency and kernel matrices for droplet pairs under different electric field strengths. It was last updated on 2026-05-24.

Use Cases

• Simulating droplet collision-coalescence processes based on precomputed collision kernels.
• Studying the influence of electric charges on cloud droplet interactions based on the provided matrices.
• Validating numerical models of warm rain initiation based on collision efficiency data.
• Analyzing terminal velocities of droplets under varying electric field conditions.

Strengths

• Includes data for three distinct electric field conditions (0, 200, and 400 V cm⁻¹).
• Data is structured as block upper triangular matrices describing interactions between 15 charge states.
• Accompanied by Fortran source code for numerical simulation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The Fortran source code may have limited readability as noted in the description.
