ATMOS-BUD is a comprehensive software suite designed for calculating heat, vorticity, and moisture balances within limited areas of the atmosphere. Developed at the Institute of Astronomy, Geophysics, and Atmospheric Sciences of the University of São Paulo, it's a key tool for students and researchers in atmospheric sciences.
- Processes atmospheric model and reanalysis data in NetCDF format.
- Outputs CSV files for spatial averages and a comprehensive NetCDF file for spatial results.
- Supports Fixed Domain, Semi-Lagrangian Domain, and Interactive Domain operational frameworks.
∂T/∂t = -Vh · ∇hT - Σω + Q
Where T is temperature, Vh is the horizontal wind vector, Σ is the static stability parameter, ω is the vertical velocity, and Q represents diabatic heating.
∂ζ/∂t = -Vh · ∇hζ - (ζω/Δp) - βv - ζ∇ · Vh - f∇ · Vh + Tilting Term
Where ζ is vorticity, β is the change in Coriolis parameter with latitude, and f is the Coriolis parameter.
∫∂q/∂t dp = -∫Vh · ∇q dp + ∫S dp
Where q is specific humidity, Vh is the horizontal wind vector, and S represents net sources/sinks.
ATMOS-BUD combines academic rigor with practical application, making it a gateway to understanding atmospheric dynamics for both educational exploration and advanced research.
The full documentation for ATMOS-BUD can be found on Read the Docs.
The google-colab directory contains guided Jupyter notebooks that make ATMOS-BUD easier to use in educational settings, especially for students and other users with limited experience working in Linux environments. The notebooks run in Google Colab and cover the main workflow step by step, from downloading ERA5 data to running ATMOS-BUD and exploring the results.
