FlowSieve: A Coarse-Graining Utility for Geophysical Flows on the Sphere ...
The core features of `FlowSieve` are: 1) computes coarse-grained scalar and vector fields for arbitrary filter scales, in both Cartesian and spherical coordinates, 2) built-in diagnostics for oceanographic settings, including kinetic energy (KE), KE cascades, vorticity, divergence, etc., 3) built-in...
