miniPBL v1.0.0

Initial release of miniPBL, a lightweight Python solver for planetary boundary layer simulation.

Features

Physics

  • 1D vertical column model for the convective boundary layer (CBL)
  • Prognostic potential temperature (θ) equation driven by vertical turbulent heat flux divergence
  • K-profile turbulence closure with convective velocity scaling
  • Automatic boundary layer height diagnosis with linear interpolation
  • Prescribed surface kinematic heat flux (lower boundary)
  • Zero-flux insulating lid (upper boundary)
  • Optional fixed lapse rate enforcement at the domain top

Numerics

  • Staggered vertical grid (scalars at cell centers, fluxes at cell faces)
  • Second-order centered finite differences for diffusion
  • Third-order Runge-Kutta (RK3) time integration (Wicker & Skamarock 2002)

Configuration

  • YAML-based configuration for grid, physics, turbulence, time stepping, and output settings
  • Input validation with descriptive error messages

Output

  • NetCDF output of θ, heat flux, eddy diffusivity, and boundary layer height at configurable intervals
  • Automatic diagnostic plots: θ profiles, BL height time series, and heat flux profiles

Dependencies

  • numpy
  • scipy
  • matplotlib
  • pyyaml
