py_eddy_tracker.dataset.grid.get_uv_quad

py_eddy_tracker.dataset.grid.get_uv_quad(i0, j0, u, v, m, nb_x=0)

Return u/v for (i0, j0), (i1, j0), (i0, j1), (i1, j1)

Parameters:

• i0 (int) – indexes of longitude

• j0 (int) – indexes of latitude

• u (array[float]) – current along x axis

• v (array[float]) – current along y axis

• m (array[bool]) – flag to know if position is valid

• nb_x (int) – If different of 0 we check if wrapping is needed

Returns:

if cell is valid 4 u, 4 v

Return type:

bool,float,float,float,float,float,float,float,float
