BetaEddyOne: A long-lived 1.5 layer quasigeostrophic eddy on a beta plane, with Lagrangian particles

BetaEddyOne is a yearlong simulation of a large, nonlinear oceanic eddy under 1.5 layer quasigeostrophic dynamics on a beta plane, initially located at 24˚N. The simulation is run at 512 x 256 resolution and is seeded with Lagrangian particles with one particle per grid point. This simulation is indended for use as a common test case for eddy-related diagnostics and analysis methods. It approximately replicates the eddy analyzed in detail in Early, Samelson, and Chelton (2011), https://doi.org/10.1175/2011JPO4601.1. The simulation was created using the WaveVortexModel (Early, Lelong, and Sundermeyer, 2021, https://doi.org/10.1017/jfm.2020.995), the code for which is available on GitHub at https://github.com/Energy-Pathways-Group/GLOceanKit. This particular simulation was created for use in the paper "A tensor-valued integral theorem for the gradient of a vector field, with a fluid dynamical application" by Lilly, Feske, Fox-Kemper, and Early (2024, in press).
